I have a 'sleeper' Shuttle XPC SN95G5 with Athlon 64 X2 4400+ and nVidia 7950GT, running Windows XP. It's a great little system for c2004/2005 stuff 😀
Re: Which slot do you like better for the Voodoo5 (PCI / AGP)?
Posted on 2021-06-16, 17:32
My PIII 933 has a PCI Voodoo5 (it’s the Mac one, flashed, so has vga and dvi) and an AGP GeForce256 DDR - it’s interesting to compare both cards against each other in the same machine.

Just thought I’d update the thread to say I got this working correctly on my soyo board after GigAHerZ correctly diagnosed user error by me :) His modded bios linked earlier in this thread won’t post on my system for some reason, so I used modbin to modify the G3 bios by altering the chipset …

hmm, ok, i used the TL866ii to flash this to a W27C512 and I get a black screen on boot, even after the cmos is reset. Are there any settings i might need to change in the programmer? Such as Region (default or flash), Start Addr, Load mode? The mobo is a Soyo SY-25P with original bios Rev .G2. I …

Sorry to resurrect an old thread, but @GigAHerZ I have the same motherboard as you and would like to use your modded bios to repalce the bios on my board. Can i ask what programmer you used, and what 28pin DIP chip is required? Or can the bios chip be flashed through DOS? ok, as the .bin is 64k i'm …

Maybe you can test UniVBE 5.3 and the FDOOMVBR.EXE executable, it's the most compatible configuration for older video cards. I've tested an ATI Mach64 VT2 PCI and it works fine for me, using both UniVBE and the native VBIOS. I'll try 64vbe, maybe it's incompatible. I wish I had an ISA ATI Mach64 to …

I can’t seem to get VBE working on my ISA Mach64, even using 64vbe. 64vbe is supposed to enable vesa 2.0 on ati cards similar to univbe, and even though it mentions 320x200 8bit in the readme, the utility doesn’t seem to give me an 8bit when I use the supplied VesaTest programme. As such, fdoomvbr …

So @viTi95, do you think sound performance can be improved? It seems to reduce fps by 10-15% at the moment

I think i need to apologise to @viTi95 for my post this morning - i think my instability issues are now caused by hardware, not the latest fdoom release. the issue seems to be some faulty dip ram i added to the amiga recently. i noticed that other stuff running on the bridgeboard now wasnt stable - …

Anyone else getting some random lockups with version 0.8.1? With both fdoom and fdoom13h This is with my TI486SXLC bridgeboard. Sometimes the machine will hard lockup whilst playing, sometimes it hard locks on quitting (for example once it’s completed a timedemo). If I go back to 0.8 or previous …

I’ll be very interested to try it, on both my DX2-66 with VLB vga card, and this Amiga with its TI486SXLC and Mach64 ISA vga card. 😀

@viTi95 do you anticipate the move to 13h will benefit 486-class processors, or will the speed increase over mode Y only be noticeable on much faster processors?

Can't believe i've only just seen this thread. This is a game-changer for the PC BridgeBoard in my Amiga 3000. Amazing work, FastDoom is superb. The GoldenGate 486SLC/2 bridgeboard use a Cyrix 486SLC/2 at 50mhz - mine is upgraded with a TI486SXLC at 50mhz. With it's 8k L1 cache it's substantially …
Re: Upgrading the VLB on my 486DX2-66: worth it?
Posted on 2021-04-29, 08:58
Thanks for the replies, that matches what I was thinking 😀 I want to keep this machine as a DX2-66 so unless there was the possibility for a decent % uplift in performance by getting a better card, it doesn’t seem worth it

I bought an XFX 7950GT AGP the other month - it worked initially but ram artefacts appeared after about an hour of use and then it rapidly refused to work at all. I'm guessing some of the ram hosed itself. Luckily the seller gave a full refund. Just this week I got a Leadtek Winfast PX-7950GT AGP …
