Re: Rendition Verite Thread

Posted on 2024-05-28, 16:36

No. I've tried. The board is not recognized I see, so it's only meant for older V1000 cards. I have to dump my QDI Legend Verite V2200 AGP card's BIOS (maybe NSSI will be of use here) to see what version it is, just to compare to yours. According to the boot screen, my card has BIOS version ending …

Is the DOS o'c tool MCLK.EXE compatible with V2x00 cards? No. I've tried. The board is not recognized What do you use to overclock on Windows? I haven't tried myself as I've acquired these boards only recently and I've yet to run in a PC with Windows installed, however I read that with certain …

Speaking of clock frequencies, Verite boards use the classic programmable PLL synth seen in many Cirrus/S3/Tseng board of early 90's: these are some working parameters that can be used to overlock the board under Windows. Mileage may vary, especially for the memory chips. Memory speed = 14.318*m/(n* …

The Phoenix bit is in every Rendition BIOS. Try running this redirecting output to a file ( I don't know whether it'll exit Graphics mode. If it doesn't wait a minute or two and reboot): https://nirvtek.com/downloads/SETMODE.20240304.005.zip MD5: c46d34c486d014a7d664133c714177da If you see …

Just a suggestion: if there is an original BIOS dump file from V2100 card (for example Diamond Stealth II) and a BIOS file for upgrading the very same V2100 card to V2200, maybe it would be possible to find out which bytes are responsible for setting the video chipset and memory frequencies. This …

Is there a way to overclock under DOS the Verite chips? I've learnt how easy it was under Windows; one would imagine that somebody thought about making a small utility for DOS, too... I also happen to have a QDI Legend V2200 AGP 8MB that is clocked at 50/100... Is there a way to flash a modified …

Aha, so every 3D engine use it's own UC to comunicate properly with GPU. Seems to be different approach from 3dfx voodoo where one glide2x.ovl driver was used by all dos games (patched by 3d patches). There's also opensource glide dxe module for games compiled by djgpp. Is there available some …

What kind of microcode is talked about? Does RV GPU chip has it's own microcode? Is is distributed separately from the driver? So driver code can load different uc files? I didn't explore verite dos drivers structure yet... where to download most rcent/best working drivers? Under DOS, each game …

Very cool, but I was referencing GLQuake. I was guessing performance on a 2xxx would fall near vQuake but since they are incredibly different in their approaches, probably never considered 486 platforms, and the beta status of the ICD it's a total unknown for me. Oh, sorry I didn't understand. …

i think VQuake 1.08 requires renaming .uc to .uc2 for v2000 .uc is used by v1000 only in 1.08 You're my hero! :) I renamed the .uc file and everything worked! Running VQuake 1.07/1.08 results in a modest fps increase. From 17.8 to 18.0 at 133MHz From 20.4 to 20.7 at 160 MHz I've tried the option r_ …

A 2nd gen Verite on a 486 is basically an unknown to me and I'd love to see where it lands. My guess would be right around where vQuake is hitting. Here you go: The system specs: Motherboard: Zida 4DPS v3.1 Chipset: SiS 85C496/85C497 BIOS Date: 10/17/96 CPU: AMD Am5x86 (ADZ) External Cache: 4 x …

Well this kinda sounds like a few issues you're aware of (bus mastering being mostly broken on PCI equipped 486 motherboards, but it being essential to good performance with a verite) and vQuake being very CPU hungry. I think you're just really bottlenecked and while there's certainly some room for …

I'm banging my head on the wall trying to get a Diamond S220 (v2100) PCI working well with a 486 DOS build and VQuake The motherboard is a Zida Tomato 4DPS, version 3.1 (unsure, but the jumpers layout matches the 3.x version and not the earlier 1.x - 2.x) - BIOS is version 1.71 - CPU is a Am5X86 …

I purchased this peculiar motherboard: https://theretroweb.com/motherboards/s/aquarius-systems-mb-5dvp One of the few VLB+PCI motherboards. It's for socket 4 CPUs (5V P5) I can't find online any manual scan or a list of the jumper settings. Does anyone has some info? I understand it's pretty rare …
