I am having the same issue you had but even with booting with an ATI PCI card it still refused to flash until I used the modified 2.15.07 file from another post, can you share the 21512SD.rom post that worked for you please? https://drive.google.com/file/d/1DgPo2mrddr9RpEVYhtUdD-F-S1Mn2dZp/view?usp …

Interesting that you ran into DOS issues with the TNT2 as it is typically the more compatible of the two. [/url] i think 3dfx is preferable to nvidia at least for build engine stuff, the nvidia cards seem to exhibit the "snow" corruption during screen tint effects (damage/picking up health) a lot …

Rage Pro and derivatives are super cheap, but very shitty for 3D in general. ATi were very adamant to implement double-buffered Vsync in Direct3D at all times, without performance to back it up, even in period correct games. So enjoy constant dips form 60 to 30 fps or from 30 to 20/15 fps, due to …

There is no way a 286/386/486 will detect the capacity of a SATA drive. This is more a capacity than an interface problem. Your best chance is to make use of the XT-IDE BIOS, can be done on a NIC but better on an actual card since your m/b doesn't have an IDE controller anyway. I do not care that " …

"Ageia was (too) similar to TNT2?"; Ageia was not a video processor per say, it was physics processing unit (PPU) so I am not sure how it could be equated to a TNT2 or any other GPU.

Interesting that you ran into DOS issues with the TNT2 as it is typically the more compatible of the two. With the V3 3000 I would recommend flashing it to the latest VBIOS rev which is 2.15.12 assuming it is not already on it and if you are comfortable with flashing cards however be warned that …

Why not flash the card with a VBIOS that unlocks the pipes?

This K1n9_Duk3 person from the links below seems to have addressed the scrolling issue. You can use ATI cards with better results for DOS gaming with the update utility below for patching problematic games: https://pckf.com/viewtopic.php?p=96074&hilit=ati#p96074 http://k1n9duk3.shikadi.net/ …

The Rage series is not recommended for DOS gaming, you will get the scrolling glitch defect in games like Keen Dreams. For 3D gaming Rage Pro and Rage 128 are meh when the driver works, Rage 128 T&L performance can be slower then running T&L off the CPU and as for the Rage II series I would call …

Keen screwups aren't ATI isolated. It wasn't the primary concern of the PC windows 3d boom era to keep compatibility up with old VGA tricks Rage 128 T&L performance can be slower then running T&L off the CPU also rage128 doesn't have any HW T&L to speak of brain fart, was thinking of Rage 6.

Avoid ATI cards for retro builds, you will run into issues in DOS. Riva 128 and TNT series will give you the best compatibility and they are dirt cheap.

For anyone else playing along at home, please find attached the latest(?) known good 3000 AGP SDRAM BIOS. I've also removed that pesky "Provided By www.V3Info.co.uk" serial number from it and fixed the checksum. I know it makes no difference, but it annoys me when people add stuff like that. Have …

Success!!! So I ordered an ATI Rage 128 XL from ebay (Cheapest PCI card I could find). Its an original chip on a new PCB made in China. Unfortunately the card only works on 3.3v PCI slots and my ASUS P2B slots are 5V. I knew this was probably going to be an issue once I did some research and a guy …
