bios woes

Hi all,

I'm locked out of the bios on an old 486 box. It works and I can
boot with Tom's disk, but I need to be able to read the cmos
password on an old Realtek 1287/1187 combo clock/battery/cmos. I've
found a small utiltity that I can compile, cmospwd-4.3, but alas -
no gcc. I've tried lists of 'universal' passwords without success.
Can anyone recommend another utility I can run with Toms's from a
second floppy, something else to try, or a pointer maybe?

	tia,
	b.
