buyerninety, thank you for your response. The next time I have this board out on the test bed, I will ensure that Vcc is reaching the B-13 pin of the CPU. I don't understand how the Cyrix 5x86 can be set to WB while the Am5x86 is not. I mean I removed the EEPROM from a working M919 board, put it in …

Are you able to tell which CPU gives a better gaming experience between the AMD/Cyrix as benchmarks don't always paint the full picture. For the brightness I think there is IdGamma. Before performing a test for best gaming experience, I downloaded Idgamma and tried my best to get it installed, …

But what can you use OS/2 Warp 3 for? Can you run Quake in OS2? For the motherboard headers, I either epoxy on a header or use an existing PS/2 header that was never wired up by the manufacturer.

Does anyone have the results for a socket 5 P75, P90, or P100 with GLQuake using any accelerated 3D card? It would be interesting to see how these systems compare. The POD100 (MB-8433UUD) results for GLQuake at 640x480x16 using the fastest available driver were: GeForce2: 36.1 fps RIVA TNT: 29.5 fps …

So you are using a USB mouse with a passive USB-to-PS/2 converter, then connecting this USB mouse to the KVM's PS/2 port? Were the results with a native PS/2 mouse any better? Your results are similar to what my testing revealed about all these protocal converters. Was the tracking quality of the …

Here are the memory throughput results. Bear in mind that on an equal FSB-to-FSB basis, the SiS 496 chipset is usually around 1-2 MB/s faster in RAM read. I think the UMC8881 is about 1-2 MB/s faster in L2 read though. This is why the memory read throughput on the Cyrix / Voodoo3 is approximately …

I would not consider the AMD 5x86 at 3x50 to be faster than the 4x40. From my experience, anything above 40 MHz will require the L2 cache slowed down via wait states (sometimes on the slowest settings) for the system to be stable. A 50 MHz PCI bus is also not considered stable. Most motherboards …

Alteration of brightness is more important in GLQuake because it has more playable frame rates compared to Quake II. Does anyone know how to change the brightness in GLQuake?

Indeed - the 66 MHz was a bit of a disapointment, however it is there for convenience. It allows you to run your PCI bus at 33 MHz and your IBM 5x86c chips at 133 MHz. I'll post the Speedsys and Cachechk results of these systems. I've put them all up on the KVM, so I can test the gameplay. Here's a …

In terms of gaming experience, I will need to run a 15 min. test of each system first. However, from my recollection of running the timedemos, the Voodoo2 is more blury compared to the Voodoo3 and the image is not as uniform. The Quake image of the Voodoo3 is overall the best, however if the image …

Yes, both BIOS revisions are the same. I even used a different EEPROM BIOS chip and reflashed. There is some other issue that I could not track down. Pipeline burst SRAM for the M919? I beleive that was a marketing ploy only as the UM8881 chipset is unlikely to support Pipeline burst. Too bad we …

AllUrBaseRBelong2Us, the UM8881/8886BF chipset does not require RAM installed in pairs. Singles are fine. The 2940U2W will work on the m919 in NT4 and W9x. It will not work at all in W2K on the M919, but will work fine on the MB-8433UUD (another board based on the same chipset). EDO RAM will work on …

This sounds like a massive undertaking, but if you have the time and motivation, this should be a lot of fun. Have you considered turning this into a kickstarter-like project?

I have had success in getting an IBM 5x86c-100 running at 133 MHz using a Gigabyte GA486AM/S v2.21 with BIOS date 7 Nov. 1995. Thus far, this is the only other motherboard asside from the MB-8433UUD which I have been able to run at 2x66 MHz. For whatever reason, I was only able to get WinNT 4.0 …

Perhaps someone else with a K6-III+ 500 MHz could share their Quake III benchmark results at 1152x864x32? Searching for a reasonably priced PCI Voodoo4/5 or PCI GF4 MX440 (with delivery to Canada) would be more encourating if I knew the expected frame rates.
