I have several 286 motherboards that act like this:
with a perfect Tadyran external battery attached, the CMOS settings can be saved and kept, including date and time. Well, as long as there is no HDD controller card or multi I/O card of any sort in the motherboard...
When Winbond, LG, Acer based IDE multi I/O controllers are present or I put in an AHA-1542 SCSI card, CMOS checksum errors come up at boot and settings are re-set to BIOS defaults.
The batteries I tried are surely healthy. What on earth is this then? Do my motherboards have some sort of power leak - ie, some ISA cards suck out all the juice at startup from the RTC... ?
286/XT gurus, please help!
