Maybe this motherboard not supports PCI bus mastering at all? Well, the obvious test is - to try this Voodoo1 in another PC.

Voodoo1 doesn't need (bus master) DMA or interrupts, it just uses memory mapped I/O.

Maybe it's a WT vs WB cache issue?

this should be easy, set clock ratio at 2x and the amd5x86 would run at 4x instead.

I realize this is about a month old so sorry for posting so late on the subject but in case you haven't gotten around to trying your other chip there is a 3DFX site that is worth checking out that may have some new drivers, game patches and other misc for the voodoo cards. That can be found here. …

jmannik, there is a jumper on the motherboard which sets the 2x/4x and 3x CLKMUL signal. You need to find this jumper and set it at 2x. It may or not be marked. I think the jumper sets float or GND to CLKMUL to determine 2x/3x. I will be home soon I will have a good look, gotta clean up first the …

Well no matter what I did last night it wouldnt set itself to 2x... It would stay at 100mhz or jump up to 120mhz but would not go to 133mhz, The strange thing is that when it jumps to 120mhz it was still set to 33mhz bus speed... I might send an email through to Gigabyte asking for a bios update if …

Make sure you are not setting the jumpers backwards. Some motherboards are unintuitive on which pin is 1,2 or 3

Make sure you are not setting the jumpers backwards. Some motherboards are unintuitive on which pin is 1,2 or 3 Lol I spent several hours on this, my memory of doing this many a time back in the day serves me well. Thankfully this board actually lists on it which pin is pin one (but I also tried …

It is possible that the BIOS is misrepresenting the CPU speed configuration. Use CHKCPU in DOS to determine the proper FSB and multiplier.

Are you are running the system with 512K single-banked (4 chips) or 512K double-banked (8 chips)? 512K double-banked is more tolerant of faster cache timings compared to single-banked 512K when your FSB is 40 MHz or higher. There were two types of errors I noticed with the SRAM. My SRAM tester noted …

Well guys, it seems that when it says 120mhz it really does actually mean 133 😜 thanks for the help guys. That CHKCPU program is really useful

A BIOS update may fix the problems you are having with the BIOS incorrectly identifying the CPU speed.

All I can say is that this Asus PCI/I-486SP3G motherboard is a real thorn in my ass - the most painful experience I've had in quite a long time. While the specs (PCI/ISA, Onboard SCSCI, PS/2 header) sound nice on paper, this Intel Saturn II chipset really blows goats. Agreed. Years ago I got one of …

A Holtek HT6542B keyboard controller has built-in PS/2 mouse support. You will need to check the wiring to see if the 7406 is wired properly though. You will want to reference http://www.vogons.org/viewtopic.php?f=46&t=36122 You can use modbin to determine if PS/2 mouse is added in the BIOS, and if …
