Soyo 6BA+, a used PII mobo. The board checked out okay but when I connected a floppy drive in hopes of flashing the bios it wouldn't boot from the floppy. Tried a hard drive with same result. Cleared cmos, reset the bios, etc. Now all it will do is to post to the point of listing the IDE drives, then it sits there.
Is this probably a bios issue rather than a hardware problem? And if so, could a hot flash be a possible solution?
Stalls at partial post
Might be BIOS problem. Have you checked if the CMOS backup battery is OK?

Load Setup Defaults in Bios and use the slowest possible memory timings - some Bios use CAS Latency 2 as default an not all memory sticks are working with this .
Make sure Floppy is set to 1.44MB and all IDE-ports are set to auto detect and cables are installed correctly .

Already done all of the above, except........I originally booted this board with a PII 233, but now have a PII 350 in it. I've been using any of three sticks of 32mb PC100, but maybe one of them is actually PC66. I'm going to put in a stick of PC133 and try again.
so many parts, so little time.....
It's possible that the BIOS is old and can't recognize the new CPU properly.

I replaced the mobo battery -- it was way down, and put in a stick of 128mb PC-133 instead of the stick of old (PC-100 ?) 32mb. Results are the same -- hangs after listing the IDE drives.
Don't have a BX chipset mobo for a hotflash. Would a 440LX chipset be too different for a hotflash?

Usually no problem .
If the Soyo Bios is 256KByte the LX Mainboard has to support this flashrom size - LX can handle it but not all motherboard manufacturers added support for bigger flashroms .

Either peel the label back and read the chip, or use the BIOS flash utility e.g Uniflash in save mode to save your existing BIOS.

Please read the FAQ from Wimsbios main page - 28 or 29 means different programming voltage not size .
Flashroms ending with 010 or 011 usually are 128KByte ones and 020 or similar 256KByte .

Alas, I'm dead in the water. My two working PII mobos have incompatible bios chips -- one is 5V, the other is the square config. I have two boards that may be salvageable, the Soyo mentioned above and an Asus P2L97A that uses a 256kB chip. The Asus powers up but doesn't post.

In general, contacts on four sides = "PLCC", pins on two sides = "DIL" or "DIP".
Are they both in sockets ? If so you are not necessarily completely stuffed.
You can buy an adaptor which will allow you to put a PLCC into a DIL socket for programming; the cheapest I have seen so far is 13 UKP but subject to carriage and Minimum Order Value. It's probably easier to find a friend who will let you "hot-swap" flash in their old motherboard.

An update:
I was about to try the hot-swap, but in the interim had discovered that the 32mb stick of ram I'd been using was being recognized as PC66, incompatible with the 100Mhz bus of the 350. (This doesn't explain how I had the problem also with a PII 233.)
Anyhow one last try iwth a stick of 128mb PC 133 was successful, and the bios has been flashed.
