So I thought I could simply take my OS/2 2.0 install on Qemu with an ISA NE2000 and simply upgrade it to OS/2 2.1 and it’d work, right?
So after an hour screwing around with various drivers, I found of all things, the PCI NE2000 will work. The driver is available os2site.com
Thankfully the NIF’s and OS2 bits work right so you can actually use LAPS to configure it, once you copy the NIF & OS2 files into the c:\ibmcom\macs directory.
And then with that in place configured for user mode networking (10.0.2.15/255.255.255.0/10.0.2.2 DNS 10.0.2.3)
