Thanks for the response. I was not aware that development of PCEM was focused only on this direction. Possibly it would be something for a fork of PCEM as well unless it could be done in a non-invasive way at some point.

As you may know, Linux exposes the KVM API which allows applications to use virtualization features, This is currently used by QEMU and DOSEMU2. There is also a proposal to use this in DOSBox: https://github.com/joncampbell123/dosbox-x/blob/master/PLANS/VMX%20core%20(using%20Linux%20KVM%20virtualiza...

At some point I wrote a script to just copy files into an (almost) empty bootable image. I use it mainly to put existing dosemu installations into PCEM, but whenever I need to put a single file inside an existing PCEM installation, I just create a second image and use it as "drive d". This...

/dev/cdrom already points to my physical drive. I needed to use an image file through cdemu though which ended up on /dev/sr1. Maybe I'll manage to whip up a patch if I need more, but for now I can continue.

Ah, I indeed found it in the source code! I just did a find&replace there, that did the trick for my test :) Btw. I can confirm that PCEM's Trident emulation is further than DOSEMU's. The 15-bit and 16-bit modes work as well (they don't in DOSEMU). Only the 800x600x16 mode appears to have odd co...

I'm trying to use a different CDROM file than /dev/cdrom. It appears that PCEM supports this, but I can't get it to work. Things I tried: 1. selecting it through the GUI 2. changing cdrom_path in pcem.cfg manually It keeps using /dev/cdrom however. What's the recommended way to use different CDROM f...

Yes, I'm using GNU/Linux. On Windows you probably have a case insensitive file system. I renamed several files now (often .bin has to be .BIN) after grepping through the source and a lot more devices are showing up now.

Possibly stupid question, but is the BIOS filename capitalised correctly? Just had a quick check of the code, and it's looking for "roms/TRIDENT.BIN". Possibly stupid, but here you actually hit the nail on the head! It was named 'trident.bin'! Renaming to 'TRIDENT.BIN' made it show up!! T...

Yep, it's there. It contains this string "TRIDENT TVGA BIOS C4.3 (24)" so I presume it's indeed for the TVGA card. The directory is called 'roms' though not 'ROMS', but it seems the other BIOSs are located properly from there.

I'd like to use the Trident TVGA8900D emulation which is mentioned in the documentation. This because I'm looking into driver issues with Windows 3.1 in DOSEMU. (1) DOSEMU emulates a similar video chip, the TVGA8900C, which may work with similar drivers as the TVGA8900D. I'd like to see whether the ...
