When all cabled up power on normally does nothing. No beep no LED no nothing. I can sometimes coax it into life by removing a link near the CMOS battery. Sometimes this just powers up LED on. Putting the link back goes onto the next phase single Beep and I get a BIOS screen. Have yet to establish any consistency in all this. At one stage with the link totally removed it would power up and down goto BIOS screen as required.
When it is pursaded to work the BIOS says AMIBIOS 10/08/99
A618301 V1.3 101199
and at the bottom of screen
It also often says CMOS NPVD Checksum error.
On the times it was behaving normally there was no CMOS errors.
Any Ideas. Thanks
