I also have this board. It's extremely fussy about the SDRAM it supports - are you using that or SIMMs? Also, it could be the BIOS has degraded. Someone I know recently had similar symptoms on a different board, reflashed the BIOS and it worked. There are versions available from here . bit rot can …

Thats the one...

Also nearly 55 Celsius on tmu with no load. Is it normal? ...

Hi, got Voodoo 1 to play with... bought it as non working. Few capacitors damaged or missing. Checked pin legs, resistors fine. After fixing that windows 98se recognise it, installs drivers etc. All seems OK but can't see anything when trying to run d3d test in dxdiag just a black screen and after …

A few years ago my Voodo 2 was flooded along with the house and I didn't have access to it until recently. When i got it again, I cleared the oxides, cleaned the contacts, resoldered the oxidized memory of the right TMU, but accidentally poked the soldering iron tip on the legs of the TMU, moreover …

Hi, anyone knows if there is any way of testing or checking those kind of chips by multimeter ot oscilloscope maybe while they are soldered or fittet in socket ? I've got a card with those chips but instead of desoldering all the chips and fitting new ones would be great to be able to check which …

Not that this will fix your issue, but for older motherboards similar to this style is recommended - https://www.ebay.com/itm/201914181739 (ISA+PCI), that's why you probably didn't get any results of yours on the working board. Hmmmm maybe that's the thing. I might need to invest in that older …

I wish I could add more RAM but that's maximum this motherboard can take without desoldering dram and sockets and then solder new sockets for 511000 dram unfortunately. If you want to increase the system's memory can't you maybe look at installing an ISA memory expansion card like the one I have in …

Hi all, I've got ECS P5VX-B Rev 1.2 Socket 7 motherboard and can't get it to work or do anything. Maybe someone has got any ideas or had simular or dame issue would be great if you can share any useful info. It doesn't post, no beeps. Nothing. Under thermal imaging cam looks like all temps are OK …

One strange thing I noticed. Although the components on the motherboard indicate it was built towards the end of 1988, the graphics card seems to be from early 1991. So either Acer was still selling these in 1991, or somebody just upgraded the VGA...but it has an Acer VGA display. If upgrading from …

The main memory is more in need, maybe. If the 286 mainboard uses Shadow memory, a humble Megabyte won't be sufficient for Extended Memory anymore. It's then either Shadow Memory or Extended Memory. That's one of the reasons why I have an aversion against 1 MB setups. That being said, it's your PC, …
