DR-DOS 5.0 and Windows 3.0

So I’ve always heard about the incompatibility, and I thought I’d give it a try in PCem.  I know I used to run DR-DOS 5.00 and Windows 3.0 (because of the CGA driver) and it worked fine.

So just to prove it works, here I am installing Windows 3.0 on DR-DOS 5

And even better, running Word 2.0! Although I did install a whopping 4MB of ram on this virtual 286.

MS Word 2.0

And to make it all the better, I changed to a 386, and re-installed Windows 3.0 and yes it runs in enhanced mode.  And I can run DR-DOS in a windows.

Of course there was the AARD code, in the Windows 3.1 betas, but as far as I know that didn’t make it to release.  I was able to upgrade to a virtual VGA adapter, and update to Windows 3.1 in standard mode on a 286, just fine

And DR-DOS worked through the standard mode task swapper

But Windows 3.1 in enhanced mode always locked up during setup.  Maybe a PCem bug?  I’m not sure.  But Windows 3.0 works great.

Windows 3.0 Debug Release 1.14

Well from popular request I finally got around to loading this up.  I went ahead with my favourite retro emulator, PCem for this, as it can nicely emulate an EGA display, unlike most emulators which do VGA, however when it comes to older versions of Microsoft products they really can detect the difference between EGA and VGA.

So to start off, I downloaded from the project page, this version of PCem, compiled it, and installed MS-DOS 4.01 , from April of 1989.  The Windows 3.0 Debug Release 1.14 itself is dated from February 22nd, 1989.  Which I figured is close enough to the time period.  I’m using the 486SX2/50 because I’m too impatient for the 386 speeds, but it does work fine on 386 or higher emulators.  It does NOT work with any 286 emulation. I’m also using the HIMEM.SYS from MS-DOS 4.01 vs the one with the Windows 3.0 (Alpha? Beta? Technical Preview?) since it is slightly newer.

There is no setup program per say, rather it just xcopies all the files to a directory, and from there you run ‘d.bat’ and away you go.  This version is hard coded to an EGA display, which again is the reason I went with PCem.  Once you start it up, you are greeted with:

Win

Windows v3.0 Debug Release 1.14

And it identifies itself as Windows Version 2.1

Look at all the memory!

And first thing to notice is that on my setup with 8MB of ram, I have over 6MB of RAM free.  Compare this to regular Windows 2.1 which gives me 399Kb of ram in my current setup.

Windows 2.1 running in real mode

And with Windows/386 Version 2.1 it provides 383Kb of real memory, along with 6.7MB of EMS memory, as the Windows/386 Hypervisor includes EMS emulation.

Windows/386 memory

Windows/386 memory

Of course the major limitation of Windows 2 is that it runs in real mode, or in the case of Windows/386 an 8086VM.  As I mentioned a while back in a post about Windows 3.0,  This was game changing.

As now with Windows running in protected mode, all the memory in my PC is available to Windows, and I am using MS-DOS, with nothing special.

Besides the limitation of being EGA only, the Debug version of 3.0 is that there is no support for MS-DOS applications, as WINOLDAP.MOD is missing.

NO MS-DOS for you!

NO MS-DOS for you!

This is clearly an interim build of Windows 3.0 as mentioned in Murray Sargent’s MSDN blog Saving Windows from the OS/2 Bulldozer.  As mentioned from the article they began their work in the summer of 1988, so considering this is early 1989 it shows just how much progress they had made in getting Windows 2 to run in protected mode.  Along with Larry Osterman’s MSDN blog post Farewell to one of the great ones, which details how the Windows 3.0 skunkworks project was writing the new improved 386 hypervisor, and how Windows 3.0 got the green light, and changed the direction of not only Microsoft but the entire software industry.

I’ve been able to run most of the Windows 2.1 applets, however I’ve not been able to run Excel 2, or Word 1.  I suspect at this point that  only small memory model stuff from Windows 1 or 2 is capable of running.  Although at the same time, when 3.0 did ship, you really needed updated versions of Word 2 and Excel 3 to operate correctly.

Windows 3.0 Debug Release 1.14

The applets from Windows 2.1 seem to work a LOT better than the one from Windows/386 2.1 if that helps any.

This is an interesting peek at an exceptionally early build of Microsoft Windows.

Bringing back the WinZork demo via jsDOSBox

So with all the excitement with jsDOSBox it was about time I tried to get something from my old java dosbox stuff running again.

As a quick note, as of right now, you cannot boot into a disk image… Nor can you really run bat files, or any kind of drivers beforehand.  It’s basically either use a script that adds files one by one, or use an image file which gets mounted, and you run your exe/com file from that.

So here we go, back again is the old Fortran Dungeon (zork) compiled with QuickC for Windows, running on the working model version of Windows 3.0.

For anyone interested my old post about this Fortran/Zork adventure is here.

 

So I was playing with Watcom C/386 8.5 today

This was the first version of Watcom that included the much beloved DOS4/GW dos extender.  Funny enough it doesn’t bind in a stub for running DOS4/GW by itself, you have to do it manually or I guess write the stub for yourself.  Another fun feature of Watcom C/386 8.5 is that it includes the win386 windows extender.

Basically it does to Windows 3.0 what DOS4/GW does to MS-DOS.  Now I’ve never messed around with win386 that much because by the time I did have a 386sx processor with more than 1MB of ram, Win32s & OS/2 2.1 were all the rage.  But in the world of VM’s I thought I’d give it a shot.

The default example is the game of life.  It compiles trivially, but the moment you got to run it you get this fine error:

Ooops!

Ooops!

It turns out that it is a timing loop error, and effects of all things Microsoft FoxPro!  The solution is provided by Microsoft, in the form of IPatchFP.exe. Naturally it is a console Win32 executable.  But with enough of the HX DOS Extender‘s runtime I can run the patch inside of MS-DOS.

With my executable all patched up, I can now run the game of life!

Conway's game of life

Conway’s game of life

Which is all very exciting.

Win386 was very cool for the time, taking the Win16 API and making their own Win32 set out of it. Another cool thing is that there wasn’t a separate runtime to repackage, as Win386 was just bound to the executable. I’m sure it didn’t fall on deaf ears at Redmond with the disillusion of Cruiser, that Win16 could have a brave new future in Win32.

And I should mention I’ve gone over a lot of the Win32s versions here.

IBM PS/1 preload software

Club PS/1!

I don’t think it’ll do anyone any good, but for some reason I’ve gotten two requests since I’ve mentioned that I’ve got a PS/1 and if I could dump all the weird software that it comes with…

Not that prodigy even exists anymore, or there is anything you can do with it, so I figured I’d just add it in with jdosbox, and you can just click along..

I guess it was unique at the time when most OEMs just slapped together some stuff and shipped without going that extra crazy mile of doing some custom programs, or even trying to foster their own online community even if it was just too forward looking, and too much of an Island for 1991.

So pastel, so Miami Vice!

There is some very 90’s feeling Learning Windows that also came with the system.. I’ve never heard of it before.  What is more interesting is that it is a Windows program, unlike the later introduction/tutors for Windows that were MS-DOS programs.  It’ll even run in real mode, which makes me wonder was it just such a major pain to put together that they swore to never do again, or was it specially made for IBM?

Introduction to the PS/1

At any rate most of the programs are MS-DOS based, there is a version of AOL that sits in between the time of Quantium Link & AOL called Promenade.  Again since the service is dead there isn’t much you can do with the dialer software.  It does use GEOS like the later AOL software, but its skinned to look like Windows (SAA?).

Oh well its a look at a distant OEM past, now IBM doesn’t make PC’s and I would almost guess that OEM’s would be forbidden or heavily shunned to make their own online social type thing, as of course everyone would be on face book ….

PS/1 2121 doing what it does best..

At any rate, I’ve upgraded mine with a semi compatible sound blaster, and a network card.. With rlfossil an Conex, its a nice BBS terminal, with good ansi support.  Sadly the bigger DJGPP stuff won’t run as I don’t have a math coprocessor, and I’m just not going to go through the motion of finding an 80387sx .. Assuming the PS/1 even has a socket for one (I haven’t seen it, but I didn’t look too hard).  But I’ve found it good with old era games, as there is some things that just don’t seem to cooperate just right with emulation.. And sometimes it is nice to have some real machines… Sometimes.

Video of Fortran Dungeon…

I forget how I got linked back to this, but I figured in the new year vogue, I’d make a video to show how … convaluted it is to build dungeon via f2c.


As you can see, first I have to compile f2c as a Windows QuickWin exe as the MS-DOS version just runs out of memory without some kind of DOS Extender, and Windows 3.0 makes a suitable extender..

Next, I had to make a ‘list’ program that then exectued f2c against the Fortran converting them to C.  Then finally I just compile the libf2c components, then statically add in the Dungeon source that was just converted.  There is some ‘out of range’ case statement, not sure why, but it works… as you can see.

It builds/runs in 286 enhanced mode and beyond..  Obviously the more memory the better.

This was on Qemu 0.15.0 with MS-DOS 4.01 & Windows 3.0

Setting up a permanent swapfile under Windows 3.0

So while I was playing around with the idea of a Windows 3.0 powered (lol) BBS I ran into one weird thing with it swapping like crazy, and eventually depleting all my disk space!

Well when I actually used Windows 3.0 back in the day, I had a 286 so I never got to play with virtual memory.  By the time I got a 386, I was using Windows 3.11 & OS/2 which in Windows you configure it with the 386 icon in the control panel.  On OS/2 it’s a line in the config.sys.

But for Windows 3.0 it’s a standalone program, swapfile.exe.  And the best part is that you cannot run it in 386 Enhanced mode, nor in standard (286) mode.  You have to first start Windows in realmode.

So now I could force it to swap on a secondary drive, or more importantly contain it’s filegrowth so it doesn’t take up the entire disk.

Idling under MS-DOS 4.01 & Windows 3.0

Well I was playing some more with my MS-DOS setup, and the annoying thing is that it doesn’t idle worth anything.

And of course running old DOS doesn’t help that most everything needs MS-DOS 5.0 or higher.

But then I found WQGHLT, which is a VXD to support idling under Windows 3.1.  And happily it works on Windows 3.0 …

The only pain is that running MS-DOS applications kills the CPU (again).  Which means that the DOS programs themselves need to idle.  And yes I did check the ‘detect idle’ but it seems that it doesn’t do what I’d hope.

Maybe it’s just the software, I should try some more and see what I get.

BBS’ing with Windows/386 & Windows 3.0 under Qemu or how I learned to love rlfossil

A while back I had seen this fantastic site, “Hates the internet” with a great write up on setting up a BBS on Qemu.  In retrospect it did inspire me a bit later to get my BBS going with Qemu, but I chose to use OS/2 once I found out about SIO’s vmodem feature.

HTI (Hates the internet) chose this program called rlfossil, which is for MS-DOS..

RLFOSSIL is an implementation of multi-line serial port driver corresponding to the Fido/Opus/Seadog level 5 specification and a simple HAYES-compatible modem emulator. It allows applications usually worked through BBS’s to run on the Internet, or in IP-based local net.er, and rlogin and telnet emulation using IP services numbers 513 & 23. RLFOSSIL allows combined work with other FOSSIL drivers (X00,BNU etc.).

So I thought between that, and all the Windows/386 excitement I’d try for something even more insane.  How about running a multiline BBS on Windows?

So in the same effort, I was going to use Qemu 0.14.1, with MS-DOS 4.01 (the first version I could find that came with share.exe), and Windows/386 2.11.  The installation of MS-DOS 4.01 worked fine on an 80MB disk image, thankfully it was one of the things that DOS 4 could do better then 3 is large disk images… Yes I know 3.31 could as well, but it didn’t come with share so it was out.  One strange thing after install was this message…

It is kind of forboding that DOS is warning me that because of my “large” disk I better run share.  Since I plan on having a multi node BBS all in one computer, I need to run share anyways.

 

The next exciting part was installing Windows/386 2.11.  The installation went pretty smooth, and with Qemu the mouse worked fine.  So far, so good.  I couldn’t use himem.sys that comes with Windows/386, nor could I use the himem.sys that comes with MS-DOS as the Windows/386 version complains that that A20 line is already active (?) and the MS-DOS one has Windows complaining that the HMA is already in use.  Sadly then my conventional memory footprint will be unsatisfactory, but I don’t see any way around it.

The next part is configuring rlfossil.  rlfossil needs a driver to talk to the network card, and you can find them on crynwr, namely the ‘other‘ packet archive, which contains NE2000 drivers.  Keeping with HTI, I’m going to use the NE2000 and configure Qemu with the PCI NE2000 driver.

Packet drivers are loaded from the command line something like this:

ne2000 0x60 11 0xc100

This loads the driver on software interrupt 0x60, and by default the PCI NE2000 is configured for IRQ 11, port 0xc100.  Qemu 1.6.0 changed the PCI NE2000 to use port 0xc000 for what it is worth..

So keeping with the HTI tradition, I’m going to put my packet driver (ne2000.com) and unpack the rlfossil archive in c:\packet.  The next thing to do is configure rlfossile which uses the wattcp configuration file.  Since I’m going to use the usermode NAT and a redirect, I configure my VM like this:

Wattcp.cfg

Address:10.0.2.15
Netmask:255.255.255.0
Gateway:10.0.2.2
DNS: 10.0.2.3

 

With that all in place now it’s time to configure the config.sys/autoexec.bat.  Some things are going to be different from a normal install because we plan to run a BBS, and multiple instances of it!

So my config.sys looks like:

FILES=96
STACKS=0,0
DEVICE=C:\DOS\ANSI.SYS
SHELL=C:\COMMAND.COM /P /E:768

And my autoexec.bat is like this:

PATH C:\WIN386;C:\DOS
PROMPT $P$G
SHARE
SET TEMP=C:\TEMP
CD \PACKET
NE2000 0x60 11 0xC100
RLFOSSIL 0 4 WIN386

And of course launching Qemu I do it like this:

qemu.exe -L pc-bios -m 16 -net nic,model=ne2k_pci -net user-redir tcp:23::23 -hda telegard.qcow2

This configures the VM for 16MB of ram (which would have cost a FORTUNE back then), the PCI NE2000, and it’ll redirect telnet from my host machine into the VM.

And just like HTI, I went with telegard, because it supports fossil based ports.

Well that sure was a *LOT* of work, and surprisingly testing it with a single node, actually works.  And you can bring up a few other MS-DOS prompts and it’ll work fine. But if you launch the second node…

Disaster struck.  So needless to say, while Windows/386 was pretty slick for the day it just couldn’t measure up.  So I figured for the hell of it, I’d try Windows 3.0  I mean I would have imagined that Windows 3.0 most certainly could NOT handle this kind of challenge.

So with some disks shuffled, I fired it up and..

Two node telegard under Windows 3.0

It actually worked!  So with a LOT of chaos going on I managed to get Trade Wars 2002 running, although I couldn’t figure out how to automatically figure out the node.. Hell the whole door configuration thing is.. bizarre. Synchronet really kicks ass in regards to easy of configuration.

Running TW2002, two copies

And using PIF’s to configure each node for some easy of launching, and some reduced memory, I could easily run all four nodes that rlfossil can support.

Four Nodes!

I have to admit, Windows 3.0 really is impressive considering all the UAE’s and how generally crappy we thought it was at the time.  I’m sure even emulated having a multiple Ghz cpu helps quite a bit.

460KB free!

And look at all that memory.. I guess it’s pretty impressive it even works.  Since Windows anything throttles the CPU at 100% I’m not going to put this online…. Although at the same time combined with an CPU idle program (is there a Windows 3.0 idle vxd?) it sits ok, but who wants a single user system in 2011?

 

Windows 3.0 …

Bill Gates with Windows 3.0 / credit:Carol Halebian

There is no denying it, when it comes to revolutionary products you simply cannot ignore the powerhouse that was, Windows 3.0 .  Simply put this is what made the Microsoft empire, broke the alliance with IBM, and changed the future of OS/2 3.0.

Not only that, but Windows 3.0 changed the way businesses operate world wide, and finally delivered on the ‘dream’ of what could be done with the 286/386 microprocessor where OS/2 had failed.

To really appreciate Windows 3.0 you have to see the world as it was before it was under development.  Back in 1989 the pc market was in turmoil.  While OS/2 had the promise of breaking all the old barriers of the real-mode only OS MS-DOS, it simply cost too much, and hardware compatibility was just too poor.  The other striking thing was that the only 386 specific feature that OS/2 1.2 (current version in 1989) could exploit was that the 386 could quickly move in & out of 286 protected mode.  The LAN server product also had a 386 specific HPFS driver, but that was it.  OS/2 1.2 was still limited to a SINGLE MS-DOS box.

OS/2 1.2’s DOS session

And there wasn’t a heck of a lot you could do memory wise.  Not to mention there was no ability for the DOS session to use EMS/XMS memory.  It’s no wonder it became to be known as the ‘penalty box’.

Meanwhile, Windows/386 circa 1987 could run multiple MS-DOS VDM’s on the 386 processor.  You were only limited by how much extended memory was in your system.  Windows/386 exploited the v86 mode of the 386 processor which allowed for hardware virtualization.  However Windows itself was a ‘real mode’ program, meaning that it had to fit in 640kb of ram, just as the VDM’s it spawned had to.

Windows/386 2.11

So unless your goal was to run a bunch of MS-DOS sessions all your extra memory was for nothing.  That also included Windows programs since they all ran in real mode.  For people with enough disk space you *could* actually install one copy of Windows/386 in say VGA, then another with a lower video resolution (CGA or EGA), then actually run Windows in Windows… in a Window.  But it really wasn’t that useful, it ran better full screen.  And all this had the effect of doing was partitioning your windows programs from each other, if you dedicated a VM per application.  Needless to say with OS/2 2.0’s seamless windows this was far more easier to setup, and frankly far more practical.

In 1989 building large applications meant that you either forced people to use Unix (SCO Xenix!) or OS/2.  For those that could afford it, Xenix would have been the way to go, as they not only ran in 386 protected mode, offered a far larger address space, but it was also multiuser!  But Xenix was expensive, needed specialized knowledge.  And as mentioned the cost of OS/2 development was HIGH, and it required your end users to have OS/2 (naturally).  And the users would have to fight that a lot of PC/AT compatible PC’s on the market were not compatible enough to run OS/2.  Despite this a lot of banks latched onto OS/2, and some still use it today (look at why parallax came into existence!).  Then out of nowhere, PharLap had developed a piece of software that changed everything, the DOS Extender.

Originally for 386 computers, the first DOS extenders required people to use special 386 compilers, runtimes, and of course linkers & extenders.  The tools were expensive, the right to redistribute wasn’t free, but end users could run your multi-megabyte (lol) applications on regular MS-DOS.  Which is what 99% of PC’s were running, and it didn’t require users to change their OS, abandon their applications, it would simply just work.

Links 386 pro

One of the earliest and most popular DOS Extended game/application was Access Software’s Links 386 pro.  That’s right this game ran in protected mode! .. And it would *NOT* run under, or near Windows/386.

It was out of this wildly great but incompatible world that the first DOS Extender vendors, tried to standardize their products with the original and short lived VCPI specification, from Phar Lap.  However in 1989 Microsoft was busy working on Windows 3.0 as the next great thing.  Using a protected mode debugger, they were converting Windows/386 from a real mode ‘hypervisor’ into a protected mode application.  And if Windows couldn’t run these new extended applications, then people would naturally have to exit Windows to run them.  And that was the major problem with Windows is that people may have an application for windows but they spent most of their time in DOS. So Microsoft’s Ralph Lipe came up with the DPMI specification, managed to get all of the major vendors to support and take over it, in exchange for leaving Windows as a 0.9 level client/server.  After all why would you need their products if Windows were to incorporate the entire 1.0 spec?  At the time it was a big deal, but the success of Windows would eventually kill the extender market save for video games until Windows 95.  There is a great article about the rise of DPMI here.

So with a firm dos extended foundation Windows 3.0 could do something the 2.x products could never do, which was to actually utilize all the memory in peoples computers.  And because it hinged on a dos extender (ever wonder what dosx.exe was?) it meant that there was no special disk, mouse, network driver/software needed as it could jump out of protected mode, and call real mode software like the BIOS, or even mouse drivers if need be.  However older protected mode programs would only error like this:

No Lotus 1-2-3 r3 for you!

Another popular application for MS-DOS just happened to be Lotus 1-2-3, and it was *NOT* DPMI compliant.  Oh sure they had DOS & OS/2 support, but would you believe that the OS/2 version wouldn’t run in a Window?  Oh sure the install program may have, but some how someone didn’t think there would be any value in being able to SEE more then one application at a time.  Not to mention the dark horse, Excel was starting to sell in 1987 like crazy, in 1988 Excel actually started to out sell 1-2-3, and by 1989 it was already over.

Lotus 1-2-3 r3 for OS/2

Microsoft Excel 2.2 for OS/2

There is no doubt about it, GUI applications were taking over.  The old ‘DOS’ interface was dead.  And Lotus had basically killed their product line by providing an identical interface and experience to their customers by providing an OS/2 application that looked and felt just like the MS-DOS application.  While you may hear that Lotus got distracted with OS/2 and missed releasing a Windows version of 1-2-3 to counter the rise of Excel, the truth is that they straight up missed windowing UI’s. Their hubris is that the users simply didn’t like the 1-2-3 interface, they wanted a windowed application.

What they did want was graphical Windows, and of course more memory!  And there is nothing more annoying than having say 16MB of VERY expensive memory in a computer like a 286, but being restricted to 640kb or less is just … insane.

So let’s see Excel in action.  Excel 2.1c shipped with a ‘runtime’ version of Windows 2.1.  Mostly because nobody was buying Windows in 1987 Microsoft had to do something to get people running the thing.  So the best way was to allow you to run an application with it.  By late 1989 and early 1990 application vendors were making updates to their products so that they could run under Windows 3.0.  And here is the first version of Excel to do so.

Excel 2.1c and the Windows 2.1 runtime

So here we have Excel running under Windows 2.1 ala the runtime environment.  All you have here is excel.  Also worth noting is that the setup program is 100% DOS text based.

Moving forward we can now upgrade to Windows 3.0.

Excel 2.1c running on Windows 3.0’s real mode

So as you can see Windows 3.0 takes up 30kb more memory then Windows 2.1!  For someone with an XT this could mean bad news!  Now it’s time to see what all the babling was about, running the same application in protected mode to access more memory!

Excel 2.1c running in Windows 3.0’s standard mode (286 and above)

Now we are running in 286 ‘standard’ mode.  Notice that Excel thinks it’s conventional memory, but we now have 14MB of the computers installed 16MB accessible to the application!  Now this is pretty amazing stuff! Now it’s no secret that the 286’s memory management left a lot to be desired, and Microsoft really didn’t want to write for it, as the 386 was where they wanted to be.  So unlike OS/2 the 286 cannot swap.  You are only limited to what extended memory you have in your computer.  But this is different for the 386..

Excel 2.1c running under 386 enhanced mode

And here we are, 386 enhanced mode! So finally  our Windows applications are clearly running in protected mode, with demand paging!  With 36MB of available memory in a computer with 16MB of ram.  The colors are distorted on Virtual PC under 386 enhanced mode… But as you can see the environment runs!  And even graphical programs that for example used CGA could happily run on an EGA system in a window.  Even better you could copy the screen, and paste it into any Windows application you want.  Yes you could buy games and use them for clipart!

Another feature of Windows 3.0 that people didn’t realize is that it could pre-preemptively multitask DOS based VDM’s

As you can see, there it is, the timeslice, and scheduling options..  Great ways to confuse users for decades… 🙂

Who could resist?

As always, there is a great InfoWorld article here.

So why was Windows 3.0 successful? A lot of it is timing, as there was no other environment that could offer people access to their whole machine without upgrading their operating system.  And of course there was the whole thing with bundling Windows, Word & Excel with new computers.  I mean who would resist something like a graphical application like Excel when compared to the klunky and significantly more expensive 1-2-3?  Sure the bundling practices were found to be illegal, but looking back, Lotus & Word perfect basically GAVE Microsoft the market.  And of course, talk about aggressive upgrades!  I’m not sure they even do such things anymore.  Although I’ve heard of big companies, and governments pushing for discounts for running things like Linux.

And there is the other things that Windows 3.0 supported that OS/2 simply did not.  For starters backgrounds (wallpapers), and of course the desk accessories.  Sure they sucked but in a panic at lest you *could* do something… where OS/2 basically left you in the lurch.  Not to mention how much more expensive OS/2 was when compared to Windows.

So with all that out of the way, what fun is a write up without a demo?

 

And thankfully I’ve found all the bits in prior posts, and I can put them together right here.
