BIOS support has indeed been dropped from modern video cards. I was hoping something like https://github.com/CSMWrap/CSMWrap https://github.com/CSMWrap/CSMWrap might work, but the README says that MS-DOS games don't work under that.
- userbinator 7mo agoThat has a very generic VBIOS which would probably work on an original IBM VGA, but the problem is that each GPU needs a specific VBIOS to switch it between VGA and hi-res modes by writing vendor-specific registers. VBIOS is effectively a driver, so given the necessary documentation or existing OSS driver source it should be possible to write a suitable one even for GPUs that are UEFI-only.
