Re: How to add small HD or CF to 386 with fixed types only ?
Posted on 2023-02-08, 20:37
One point to add is the 386 laptop floppy is not working so I am trying to add the drive overlay using a Pentium 4 system. Could it be the drive overlay software is checking the P4 bios and thinking an overlay is not required with an 1GB or 2GB drive and not installing one? I think I remember your …

Try the EZ drive overlay software. It works much better than Ontrack in my opinion. Seems to be more compatible. Uses standard partion types. http://vogonsdrivers.com/index.php?catid=19
Re: Acculogic RAMpAT! - Anybody with a working card here?

I did install the RAMpAT into my 286 and found that my RAMpAT config screenshot matches that of pshipkov's, implying that the system is not relocating unused reserved RAM. Unfortunately, when using the RAMpAT in my 286, I would get PARITY ERROR ??? SYSTEM HALTED_ when trying to run DOOM. Doom …
How often should an old PC get power?
Posted on 2023-02-04, 18:19
I've got a couple old PCs lying around. OK, maybe more than a couple. I'm sure most of you do to. Most are not connected to AC power and are rarely powered up. How often should I power up the old boxes and for how long to keep them in the best condition? For example, I try to power up the old XT for …

Re: An IDE disk initialized on an older machine is inaccessible on my late model pc
Posted on 2023-02-03, 01:17
I bet the old PC was using CHS addressing while the new PC is trying to use LBA. Unfortunately it can be very difficult to force a modern PC to use CHS when your storage device supports LBA, because the new PC really don't expect anything but LBA. If your BIOS is newer than 2001, you should be able …

Re: Identifying an VLB graphics/controller combo card

There's some CL boards identified as Gainward on VGA Legacy that appear to have the same serial number sticker and oval QC OK sticker, but those also seem a bit generic. You have a 9301-01 card.

And the octek cards use a different floppy IO controller too, now that I look at it. Sometimes the FCCID can be on a sticker that falls off. Or maybe this was never intended for the US. Can you dump the VGA bios? There might be a reference to the OEM in there somewhere.
Re: Identifying an VLB graphics/controller combo card

Looks similar to the Octek VL-COMBO, although the part number formats don't look similar, so it's probably not Octek. https://www.vogons.org/viewtopic.php?p=1025211 Cards from this era should have an FCCID that identify the manufacturer if you look them up on the FCC web site.

Did you have the switches set for the correct cache size? looks like you have chips for a 256k cache.

If you are able to jumper the board for a reduced cache size, then you have some spare chips you can swap for testing. A small L2 cache is much better than no L2. It would help if you posted a picture or the name of your motherboard
