For completion of information about this board, there’s a bug in the BIOS, which disables the floppy controller by default, while it’s set to enabled in the BIOS. How to resolve that issue: 1. Disable floppy controller in the BIOS, save settings and reboot. 2. Enable floppy controller again, save …

@Deksor, as you’ve mentioned that the IDE interface actually uses the ISA bus deep down, would it be possible to allocate a BIOS ROM in memory, just like an EEPROM would be connected to the ISA bus? Like with an XT-IDE card. Exploiting such a connection could definitely bring some more cards to the …

I've had one of these boards for a few years, but am only just starting to build a system around it now. But it won't POST. I've verified that all the jumpers and resistor networks are configured correctly. I'm using a DX/50, which has been tested in another 486 board, along with the parity RAM and …

I've eventually decided to go for, you would've never guessed it, an eraser. :) I got myself a rather large chunk at our local Dutch Hema departement store. Due to the rubbery properties of the eraser, I just cut a couple of cubes out of the eraser, after which I've cut out some slight indentations …

There does not seem to have been a universal solution for slotket brackets. Some models came with full covers, some models came with motherboard brackets plus a latch over the top and some models came with the little clips as in your example photos with the Eagle 30-900sp-000-42A. The slotket in …

Hi Guys and Gals, I'm kind of hoping you can be of any help, as the slotket adapter in my IBM PC 300GL is quite loose in it's slot, which causes a system crash when bumping the table... :face_palm: https://www.vogons.org/download/file.php?mode=view&id=113550 Sure, I can put a random piece of plastic …

Hi there, I was wondering if anyone knows anything about this header. It seems only logical to be able to send the PC speaker signal to this header, but it does not work at all. I’ve done some research about it, and came to the conclusion that the Gold variant of the AWE64 isn’t supposed to have a …

@Madowax, could you perhaps provide the files for this specific motherboard, necessary for modifying the address from 330 to 300 on the SCSI card?

We'll just have to test it then. :) I mean, it's definitely worth it if it in fact works. If it's just a placebo effect we're talking about, it's quite useless. I haven't read into TRIM enough to know exactly how it works though, so I'll start with that to get some actual results. I have done some …
