Great. Thank you for confirming this! Any idea if the TNT Windows 98 drivers work on a 486?
Anyone have a RIVA TNT PCI card and a UMC motherboard?
Posted on 2012-07-02, 08:16
For anyone who has a working RIVA TNT PCI card (not a TNT2), could you test to see if a UMC 8881/8886-based motherboard will power on with this card inserted? Many thanks!

it freezes on many Cx6x86 systems on the MSR testing, ...[?] so I really doubt the the output from time to time. I can tell you how to fix that for good! First, if your BIOS has the option to disable Cyrix CPUID, disable it. If not, use the ibmm1.exe or ibmm2.exe software to disable the CPUID in …

I'm pretty sure the VIA and OPTI are junk on the PCI platform. I suspect Intel is on the slow side, but I have high hopes for the ALi. I'd be willing to run a detailed chipset comparison, but I'm lacking VIA, OPTI, ALi, and Intel boards. I don't really want to pay anything for VIA and OPTI boards, …

@FGB Speedsys also notes that my UMC boards are PCI 2.10. I've never seen Speedsys say a board was PCI 2.0, so I'm not sure how reliable it is. At any rate, the UMC boards won't turn on with a Voodoo3 in place, so I'm not sure if the issue is entirely PCI revision related. That is good to know that …

I would suggest making very good friends with someone in Europe and someone in the US. Use their place as an eBay dumping ground. Then in the next 0-20 years, if you so happen to visit Europe or N. America, pick up your goods. Alternately, have your very good friends ship your items to you by boat. …

We know that a Voodoo3 will work in SiS socket 3 boards. It will not work in UMC socket 3 boards. Has anyone tried a Voodoo3 in an ALi, OPTI, or Intel socket 3?

For anyone else who even toyed with the idea of buying that board, the guy wants 56 euros just for shipping (to N. America)!

Are you sure it is the PCI specification which limits the use of the Voodoo3 on the UMC board? According to the Tomato manual, it also uses the PCI 2.0 specification. I think there is more to it than that, but I don't know exactly what the limiting factor is. I've heard reports of some SiS boards …

[Note, if your BIOS does not have an option to disable CPUID, you must disable CPUID in software to run SpeedSys with an MII]. How to do this feipoa? There are programs which you can use to alter the register settings of Cyrix 6x86, 6x86MX, and MII CPUs. A few names come to mind, such as 6x86cfg, …

Anyone see this motherboard on eBay? http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=190674522311 Visually, it looks like a decent board, but I cannot find the manual online. The price is too high for me, but if anyone here has bought it, could you let me know how it performs? I don't have a whole …

Take a look at this odd 486 board on eBay, http://www.ebay.com/itm/Itox-Motherboard-g486vpc-/300734194334 The PCI slot is shared with an 8-bit ISA slot. And there's only 1 PCI slot. This is likely one of those industrial 486 boards. It also uses a VIA chipset; weren't those buggy with PCI slots? I …

Interesting... I'll check my solder work and try putting 256KB of cache back in. You should desolder your RTC and put in a RTC socket with a new RTC.

Your Speedsys L1/L1/Memory are right where mine are for an AMD X5-133. These are the results for a good quality/fast socket 3 board. Cachechk results are also right in line with a fast socket 3 board. With my Zida board and a Voodoo3 3000, I get VESA 22241 KB/s. Same value using a Matrox Millennium …

Well that explains a lot! The 4DPS board requires a short for the turbo button, whereas the PCI400-4 board has removed that jumper header. The 4DPS board is now performing as expected. The original poster of this thread should also short their J1 2-3. Our cachechk scores are now in agreement. By the …

Thank you for uploading 4.00A BIOS. Unfortunately, it did not fix my L2 and memory speed issues. Perhaps you can upload a Speedsys image of your 4DPS w/AMD X5-133 and of which chipset settings you are using? You do not need a Cyrix 5x86-133, you can use an IBM 5x86-100HF and run it at 2x66 for 133 …

Beating those scores shouldn't be very difficult. I am only trying to discover why the 4DPS is lagging in L2 and RAM throughput. For the results you are about to present, please ensure they are from the 4DPS board using an AMD X5-133 at 4x33. If all we need is BIOS 4.00A, I'm excited! For the all …
