I don't know if this is of any help to you. My board is the VL/I-486SVGOX4 which I believe is near identical to the VL/I-486V2GX4. It has 4x 30pin and 2x72pin instead of 4x 72pin memory slots. I believe the large capacitor by C35 is 330uf 16V but not to sure. What is it you're trying to achieve? Is …

Cache memory nightmare! Cache memory arrived and fitted. Now shows 256KB and tried to boot but it shows the HDD is corrupted. Realized on leg was bent and missed the socket but sorted that out. But unfortunately still had the same issues. Disabled the cache. HDD access is fine. http://i185. …

I'm guessing that keyboard uses buckling spring switches? Yes it has buckling spring switches. I'm using this keyboard right now on my main rig. It is the Model M2 which has the same buckling switches as the original Model M. The keyboard does not quite have the weight and build quality of the …

Yep I think the IBM hardware upgrades are complete. It now has 2x 8MB 60ns fastpage ram and changed the HDD to a seagate 1.2GB and cloned the old drive over so I do what I wish without loosing any of the original Aptiva software. I do have a AMD DX4 100 MHz CPU however it's 3.3V and I think the …

Cheers guys! :-) Not sure if I wish to put OS/2 never thought about that. I don't own a copy of OS/2. More hardware changes. I have added a Ethernet adapter. I have changed the memory. And added cache memory which is 128KB That is the maximum that the Aptiva can take. http://i185.photobucket.com/ …

Great cleanup job! Did you take care of the PSU as well? :happy: (And nice attempt to spell VOGONS with the keyboard keys :lol: ). Cheers! :-) Oh yes the PSU has been cleaned. Although not opened. Did my best not to make the fan spin too much with the air gun. All the components on the board and …

All cleaned, maybe the odd bit to do but it's much better now. The base unit was a breeze to clean. Took it to work and used our air compressor to get rid of the loose dust and finished it using cyberclean putty. The monitor was easy too, that just had lose fluff inside so did'nt even take the back …

Nice machine! I really like these compact cases. It's a IBM Aptiva 486DX2 66 MHz, I don't know if it's Intel or not yet. Probably IBM :lol: Also, no cache installed? I think your right, still yet to check though what brand of CPU it is. Yep I'm afraid no there is no cache memory installed :-( …

Just picked up this fine example that I won on eBay for just under £30 in my local area. I went and collected it just an hour of the auction ending. It's a IBM Aptiva 486DX2 66 MHz, I don't know if it's Intel or not yet. Showing as 16MB RAM, 540MB Hard drive, Quad speed CD-ROM, Sound Blater 16 VIBRA …

@ brad1982_5 Good find with the picture... was that from the internet or did you scan it from an original - if the latter, can you see what markings are on the chips on the pictured 'pipeline burst SRAM module' ... (well, call me a sucker, but that pic makes me think that the PB module perhaps …

I don't know why i'm afraid I've never had that problem. My board shows the L1 option OK. It's a V3.4B/F with a AMD 5x86. Are the BIOS revisions the same on both boards you have? Subject change I wonder if the Pipeline Burst SRAM Module's ever got released? http://i185.photobucket.com/albums/x305/ …

Move the JMPCFG Jumper from 1-2 EPPROM Setting to the 2-3 Software setting. Hopefully this will solve your problem. I have a similar Waverider PRO 32 which is the non plus version and I briefly remember "Sound Card not detected" when the cards JMPCFG jumper is set to EPPROM setting.

According to my experience the screw holes match perfectly. You just have to screw in the gold risers in the right places that's suited to your motherboard. Early ATX cases even had a guide with AT-ATX words stamped inside next to the screw holes that where an AT or ATX board is expected to be.

Yes I think I know what you mean. The cache sticks usually state "FOR M919 USE ONLY" Why my one doesn't I don't know. It does show as having 256KB cache memory after post but I have never ran any diagnostics to check it any further. I got the board at a car boot sale many years ago so I don't know …
