Typically even Geforce 6/7 cards do not list 1600x1200 but 1280x1024 as the biggest supported resolution. Also some cards (e.g. my Inno3D Geforce 6600 AGP) do not list even 1280x1024 as a supported resolution right after boot in DOS, but it lists 1280x1024 after you booted Windows and drivers …

Try to check configuration *.ini files in drivers folder there are some parameters to enable and disable MPU-401 also try more games and sound tests in their setups..

Fortmedia FM801 installation is problematic, first of all DOS installation package still needs to be extracted in Windows and after i can install it on my VIA machine, because of classic runtime R6003 and R6002 too fast machines errors. I tried setmul for slowdown its not working. I tried bypass by …

I wonder if its possible somehow on software side fix, that 1600x1200 is not available on some modern cards, or its rom thing? BTW roms, its probably last big think to address here, more modern cards, i dont remember with which lines it exactly started, have different boot / dos clocks for 2D and …

This Windows stuff is nice too, but i wanted to know if such info is available even in DOS in theory, or is inaccessible from it. I don't think such information is available in DOS from the Bios ROM area at 0xC0000. This kind of info would occupy valuable space without any advantage since it's …

+1 for VBsize, few days ago i discovered that Navratil System info has Video Bios size info too and its always the same as shows VBsize, but i tried to use it for my X58 machine and its shows at the start, too many PCI devices error and probably its not designed to work properly on system with …

I benchmarked some cards with vid_nopageflip 1, it seems that it is silver bullet solutions, so we can congratulate Falcosoft to his find.

We have first result which shows that card manufactor actually matters, my Microstrat Geforce 7600 GT reports Vbios size 59KB, Falcosofts Inno3D only 55 KB. My cards its PCI-E with 2x DVI + S-Video, maybe it matters too.

Problem with Checkit: As I said in some cases Checkit can report video bios + option ROM together as one continuous occupied area labelled as 'Unknown ROM'. In this case the real Video bios size is actually less than 64 KB but AHCI option ROM is enabled. Someone can misunderstand this and falsely …

Make sure you do not compare results you got with VBSize vs Bios File (Bios dumps) vs Checkit. Ok its more complicated than expected. VBSize and debug method report the size of the memory payload. A BIOS file contains headers, paddings, parts that are irrelevant for DOS etc. so it's usually bigger …

Thanks for explanation and results, especially G960 looks nice, i expected 72 KB or something like that every KB counts. BTW does make such optimizations sense for Pascal (at least Borland Turbo 6 or 7 i dunno know), i mean back in day 20+ years ago, i was taught than Pascal is very slow in …

Of course more results are always better since they can show a more detailed picture, but it means more work for you/for your contributors.
