Hi all, I just hooked up my 166mhz computer again for the first time in a while. The CMOS battery seems to have died (or rather it says "low battery" but it acts as though it's completely dead).

I was hoping to still be able to boot because it seems to autodetect my drives correctly. Unfortunately it's acting weird. It insists on booting from A:, which is fine since I've got a boot floppy (several of them, which I tested and found to still be working with another computer). But it just doesn't seem to want to do anything. It says "reading boot record from floppy..ok" and then does nothing. Eventually when pressing any key it does it again.

I haven't been able to figure out how to get it to boot or why the boot floppies don't work. Unfortunately this BIOS doesn't seem to have the option to select a different boot drive one time, as far as I know, only by changing the order in the BIOS, which doesn't work.

Anyone know if there's anything I can do? Unfortunately it's one of those CMOS batteries that requires desoldering and I'm terrible at that...but if I can boot into the system somehow, even just to a floppy, I'll probably be able to use the 5.25" drive to archive some files.

The motherboard is an AOpen AP53.
