UPDATE 2: I'm an idiot! I was trying the board with a Pentium III CPU, only took some hours for me to look at the back and realize it.. It works great with a PII of course.. So a 27c010 it is!

I don't know really.. I have a post card that displays "-- -- " so no codes or anything. Nothing gets hot either. RAM and CPU are known good. The board is in good condition overall so no damaged traces or anything. Since the EPROM was missing I started with that..

Update: Tried W27c010 and W27C020 and it didn't work. I also tried the AH6_KQ version of the BIOS (no 128GB support) and it also didn't work.. Just I'll wait for someone with the same board to see this...!

Hi all, I got a AH6 v1.02 that is missing its BIOS EPROM. I thought it would be easy to find an image of its original BIOS and the EPROM type needed but I only found this one : https://www.bios-mods.com/forum/Thread-Abit-AH6-KQ-128GB All other links are dead or unavailable. This image seems legit …

Thanks I think that's it.. The modules I was trying were EDO but I tried some other modules that were also EDO just different make and it worked. Since these pass the extended test should be left there or I'd better replace them with FPM type.?

I have the same exact motherboard but it has empty sockets installed instead of fake (or real) cache. The problem that I have with this board ( apart that I need to populate the cache) is that it only recognizes RAM installed at the 30pin sockets, if I remove those SIMMS and install a RAM module in …

Re: Is there an IBM Aptiva "restore CD" with DOS/win3x ?
Posted on 2022-03-26, 01:36
That's what I was thinking about doing.. I do have a working Win 3.1 installation and it's easy to put files on my HDD since it's an SD card. Do you remember if this application is on the CD contents? I mean if I copy the "restore" folder on my hard disk will I be able to run an application from …

Would it be possible to do this without a functioning CD-ROM? Sadly the CD-ROM on my 2144 machine does not seem to be functioning ..
Re: ISA GPU for 286 Build
Posted on 2022-01-24, 15:13
I got this from eBay https://www.ebay.com/itm/174772780600. It's based on the Cirrus Logic CL-GD5401-42QC-B and has 256Kb of VRAM. I think it's period correct for my mainboard but seems a bit trashy. Hopefully it will do the trick; I paid a bit more than $30 for this POS:P
ISA GPU for 286 Build
Posted on 2022-01-24, 11:11
Hi all, I found an old 286 motherboard that doesn't have any markings that specify model or make, featuring a 10MHz Siemens processor and 1MB RAM (DIP chips but it also has unpopulated SIPP sockets). The seller claimed that the board is fully functional so I got it but I don't have any ISA graphics …

I wouldn't bother with IDE interfaces on soundcards anyways. It's not an IDE interface, it's a proprietary Panasonic/Matsushita interface. Perhaps the damage is because someone tried to plug in an IDE drive? Yes yes I know that it's not an IDE interface..even if it looks like one. Maybe you're …

I was always careful near open PC cases ;I'd never stick a screwdriver or loose cables near components or cards while the pc is running so this kind of damage is really new to me..! You can bet it was a human mistake;luckily the item worked this time but no more buying from local ads without asking …
Re: Sounblaster Pro2 hardware damage
Posted on 2017-01-10, 15:11
If that's the main power line maybe I could try strengthening that trace with larger copper wire and more solder throughout to protect it from corroding further.. I don't have any epoxy solder coat at hand so plenty of flux and a dab of solder could effectively protect it. If you look closely on the …

Yes I can hear sound so I'll just leave it alone. I wouldn't bother with IDE interfaces on soundcards anyways. Thanks again for your insight;I'd made a fool of myself if I phoned back the seller for what it turned out to be a user error. (although he could've told me about that trace).
Re: Sounblaster Pro2 hardware damage
Posted on 2017-01-10, 14:23
Hmm,I think something voltage/current related could've damaged that trace because of the copper discoloration and the slightly carbonised solder mask underneath. Maybe you're right and by scratching this area weakened enough for a regular voltage to be able to destroy the remaining trace. It's a …

Thanks so much kixs!I totally forgot about that. I just tried it and it found a "Soundblaster Pro"! The PC asks for the Win95 disk and I've no idea where I've put mine. I will report back when I install the drivers!
Sounblaster Pro2 hardware damage
Posted on 2017-01-10, 12:52
I purchased a SB Pro2 a while ago and today that I got to test it I found out that the card has been damaged. A trace near the IDE connector next to the resistor packs has been burned out (too much current maybe) and a jumper wire has been put in the back of the IDE connector as a failed repair …
