[comp.sys.ibm.pc.hardware] xcmos checksum failure

eehamid@cybaswan.UUCP (ia.hamid) (10/11/90)

Hi, I posted an article earlier about my problem but havent read any
reply. I am trying again just incase the first mail got lost.

The system:
	1. 386DX at 20 MHz with AMI Bios.
	2. 2 Meg RAM.
	3. Paradise+ VGA
	4. GUI: Windows 3 / Enhanced mode.
The problem:
	1. After turning on, the RAM checking routine ticks at HALF its
	   normal speed.
	2. At the end of RAM check, 3 beeps and error message displayed:
	   xcmos checksum failure
	   To resume press <F1>
	3. Boot up continues and system operates normally, I think. Can't
	   feel any performance degradation.
The Question:
	1. Is the system configuration - AMI Bios, screwed up?
	2. What does this mean in terms of hardware and performance?
	3. What must I do to rectify the situation?
	4. Any suggestions or pointers !

The END.

   Define "its normal speed".  Does this mean you've changed something in
your configuration and this problem has appeared?  If so, try putting the
configuration back to the way it was and see if the problem goes away
again.  This will give you a better idea of what's going wrong.

$	2. At the end of RAM check, 3 beeps and error message displayed:

   Try re-running the setup program.  Make sure everything's set
correctly.  Write the information back to the non-volatile memory and
see if that helps the problem at all.  It's possible that the information
in the CMOS RAM got changed slightly, though I don't know how that could
produce the half-speed RAM test you mentioned.  It's worth a try, though.
