Desqview/X

Desqview/X

I never used Desqview back in the day, as I didn’t have a good enough computer. A 286 with 1mb of ram just wasn’t enough to push the thing. And by the time I did get a 386, OS/2 2.1 was all the rage. But in that time between OS/2 2.x and the release of the 80386 CPU there was all kinds of programs to take advantage of the 386’s v86 mode.

Desqview X really is different in that it not only incorporates the desqview multitasking, but it also supports the X11 protocol found in the UNIX world. Sounds cool right? A friend wanted to run it, so he actually dug out a web page, chsoft.com with all the bits.

The first stumbling block is that Desqview requires that you use the memory manager QUEMM, which the majority of emulators we tried couldn’t work with it. Qemu 0.14.0 however proved itself up to the task, as long as you didn’t let it do the aggressive optimization, just let it install, and reboot.

Installing DesqviewX was pretty straightforward, the only catch was the video. VGA doesn’t work but the SVGA modes work fine. I just used the 800x600x256 mode.

With that out of the road, the next thing needed was a good mouse driver. For some reason the majority of the mouse drivers I tried just wouldn’t work with desqview, until I tried ctmouse.

Naturally for the whole X11 experence you need networking. The tcpip package on the desqview webpage uses some old netware thing with a ne2000 driver that is hard coded to 0x300 irq 4. Which won’t work in any machine I know since everyone has at least one com port. So I had to take the lsl & ne2000 parts from my Netware 3.12 client. But doing so revealed that the lsl wouldn’t run because of a lsl buffer pool error. And of course to work with slirp you need to be running ethernet_II instead of 802.3 …

So you’ll need a net.cfg like this:

link support
buffers 4 1504
mempool 8096
max stacks 4
link driver ne2000
port 300
irq 3
frame ethernet_ii

Naturally you’ll need to change the source to Qemu if you have your own build to use IRQ 3 instead of 9 (it’s in hw/pc.c), or use one of my binaries. It’ll configure via bootp and at the end you should be able to ping 10.0.2.2

Putting it all together, running it like this:

./qemu -L pc-bios -hda packet2.qcow -net nic,model=ne2k_isa -net user -redir tcp:6001::6000

On OS X has qemu listen on 6001 for X11 sessions, then redirect them into the VM on it’s X11 port. So I could then easily run xeyes like this:

xeyes -display 127.0.0.1:1

And the output appears inside of Desqview X. Likewise, removing the session security, and allowing remote connections in OS X’s X11 widget, then allowed me to send xeyes from Desqview to my mac like this:

xeyes.exe -display 10.0.2.2:0

And exeyes pops up on OS X as running from the Desqview VM.

I don’t know if it’s terribly useful, but I thought someone may get a kick that Desqview X can run on Qemu 0.14.0 In this day & age though you can get easier versions of X11….

About neozeed

What is there to tell? I've loved UNIX like things since I was first exposed to QNX in highschool (we had the Unisys ICONS!), and spent the better time of my teenage years trying to get my own UNIX... I should have bought Coherent in retrospect.. Anyways latched onto Linux in 1992, and then got some old BSD admin books and have been hooked on the VAX BSD & other big/ancient things since...!

One thought on “Desqview/X

  1. Thanks neozeed for redirecting me to this post.

    I used to be a user of DesQview in the 386 and 486 days and DesQview/X featured in the DesQview User magazine a few times. It was totally overkill for anything I needed in the day job though so never got purchased.

    I eventually came across 2.0 and 2.1 in a.b.w and I think those copies got archived on the chsoft website. I did have it running at one point on a Pentium mb with a Western Digital Paradise VGA card.

    I did scan the magazine articles which are still available on chsoft.
