Sorry for the necro. The manual I found for the V35N says: Ether-SCSI card slot. I know Acer made a VGA/SCSI combo card which looks to have the same extended piece compared to a PCI card.
Re: Where can I find "AMIBCP" (for DOS) ?

The oldest Windows version I have is 2.42. The oldest DOS version I have is 5.11E. It would be nice to get a hold of every version between 1.0 and 5.0, but I'm feeling pretty pessimistic about this. The odds are about as good as finding a MR BIOS image for the VLSI topcat. I would like a copy of …

Start with checking if any of the power lines are shorted. Swollen capacitors are always bad news, be it shorted or open circuit.

My question apparently was not clear. Does the 6VIA85 have VRM8.4 spec voltage regulators that can handle Coppermine CPUs, from the factory? As for the jumper, thank you for explaining.

Found some inaccuracies in the specs of the Aopen 6VIA/ZX85 (6via85): https://www.ultimateretro.net/motherboards/7956 - the motherboard supports FSB 66/100/133(OC)--> page only lists FSB66/100 - it supports Celeron (Mendocino), Celeron (Coppemine) and Pentium III (Coppermine) --> page only lists …

Re: Help identifying P54TA Socket 7 motherboard
Posted on 2021-06-09, 13:48
The P54TA is a board of its own with a FuguTech/PCChips bios for the M506/M507 board stuck on it. But those have 3 PCI slots, not 4. The 4 PCI on the PM-7500 was indeed a typo, most likely that is from a late-night binge-add session, my apologies. So we have a board that has white ISA slots such as …

Congrats on getting it to boot. As for identification, OEM version, I don't have information on manufacturer ID 006257 right now. Will see if I can find more info. In the mean time, if you can manage to make a backup of the bios (you can use this tool): http://cd.textfiles.com/microhaus/mhblackbox3/ …

Is there any markings/brand on the board? That way we could try and find settings and specifications for it.

PCCHIPS M919 that I have laying around doing nothing. Not sure what's wrong with it. I bought it at RE-PC in 2018 and it's been bricked the whole time I've had it. Starting to wonder if the Flash BIOS is borked because I tried flashing it in my FIC 486 PVT and it said the chip was not a flashable …
