how to test psu and reset to cmos to default
hi,
x-posted this is not a very popular topic as i keep losing people :-) but i'd appreciate any help. ibm aptiva 2159-s90 (1997; split system; win95B) SUDDENLY for no reason, had post-start-up errors (date and time change (they hadn't changed) and config change -- referred to the floppy drive)) the floppy was fine (basically) i changed the battery last pm and it wouldn't pass the post (at all) cleared the cmos (paper btwn clip and battery overnight) it booted this am; many post-start-up errors (some phantom) currently: the cd-rom (in the media console) is running however the pc won't recognize the win95 cd (the cd-rom is set as the 4th start-up device) the post-start-up error now is: "adapter card resource error" which i think refers to the media console controller card (since it's in an isa slot) i have NO CLUE what to do about that. so i want to get the pc to reset to factory settings and don't know how to get this (it is not listed (although it used to be)) i need to test the psu and want to make sure that this is correct: i'd put the positive (red) probe (backprobe) to for example the red wire on the power cable to the hd and THEN ground it (for example using the p8-6 and p9-1(the center black wires on the power to the board adapter?)) any help is greatly hoped for and appreciated |
