Patience does pay off! Letting the PC sit without the battery for 48 hours or so did the trick. Thank you guys for all you help. Now, there are a few more things I have to set up - enter the HDD data, somehow reverse the 7-segment display (it now shows 20 MHz when it should be 40), check that …

The guy who replaced the battery for me said he used Schottky diodes, I think they are soldered on the other side of the board. I will check for conductivity. Currently, 2 16-bit ISA slots are in use (graphics card and IDE/FDD controller card), they both seem to be getting power. Once I (hopefully) …

It asks for the password before booting. It doesn't seem to read from the two floppies before asking for the password. OK, current plan: 1) Try with another floppy drive (a tested one; only one floppy drive connected) to see if it gets read before the password prompt gets displayed. That would then …

Guess that can't hurt. OK, so the barrel battery was replaced with (initially a flat) CR2032. I would say that about 24 hours went by before I inserted a charged CR2032. I will go ahead and pull it out. What would you say - three days, over the weekend? Or a week? 😀 Br

Thank you quicknick, I'll check that out. Probably won't buy a programmer just for this occasion. The guy that helped me with the battery already mentioned that he doesn't have one for chips this old. If any of you guys could program the chip for me, and you live in the EU, please send me a PM! …

Well, after swapping the battery for a CR2032, the "Enter CURRENT password:" message still shows up. I even unplugged the IDE/FDD controller card - no change, so it's definitely a BIOS lock. There are a few pics of the board in the attachment. The BIOS chip is AMIBIOS 386DX ISA BIOS 1992 AA1078870. …

Hi Horun, thanks for the info. There are two "jumpers" in the vicinity of the battery - one 2-pin (covered) named W1, as well as a "4-pin" (pin-empty-pin-pin; none covered), named J1. I'm guessing that the external battery connector should be found somewhere near the integrated battery? Br

Hi, I bought a QD-U386DX with a 40 MHz AMD CPU. The seller didn't specify that it was password locked. After attempting to enter some master AMI BIOS passwords and playing around with the Keylock function, there's been no success. So I've now decided to discharge the barrel battery. Do you think …

I had the same issue, with the error popping up and MIDI music being stuck. What helped was using the 2048 drivers and also making sure that the card has correctly configured resources for DOS/legay sound emulation (reserve the appropriate addresses in BIOS).

ESSVOL has no effect on any volumes. The same goes for changing /v and /s values in autoexec.bat Trying to run SETVOL says that the card is not initialized or something along those lines.
