As a quick aside, on my exploring early OS/2 betas I thought I’d try to emulate the machine that I’d clearly lay the blame as to why OS/2 was fundamentally a failure, the IBM PS/2 model 60.
So IBM machines don’t use built in ROM config programs, but rather you need the reference disk. And this being a Microchannel PS/2 machine you also need the config files to support things like more than 2MB of RAM, the ESDI controller, or even an AdLib/SoundBlaster card.
Adding in the RAM card, and a sound blaster adds the following cards:
However it’s worth noting that the default ESDI config/driver on the MCA confg disk won’t work on 86box. You will need an updated version.
So inside the diag disk the config will appear like this:
I’ve uploaded the reference disk on archive.org here: 86box PS/2 Model 60 Reference Disk : IBM : Free Download, Borrow, and Streaming : Internet Archive.
Unfortunately, at this moment 86Box’s PS/2 model 60 can’t run OS/2. The model 80 however has much better luck. But for anyone who want’s to play Wolf3D on an emulated 10Mhz 286, well this is your big chance.
