Is my A7N8X Deluxe BIOS corrupt ?
Posted on 2004-08-19
Anyone got any thoughts on this problem ...
System spec Asus A7N8X Deluxe rev 2.0C
Athlon XP 1900+
512Mb memory ( 2*256mb DDR )
Nvidia geforce II TI200 graphics
Maxtor 60Gb harddrive
Windows XP professional SP1
System was working fine, freshly formated and reinstalled after problems with XP SP2, decided it was a good time to get up-to-date with drivers and bios etc .... big mistake ! BIOS flashed from 1007 to 1008 using ASUS windows update utility. Flashing completed successfully and system continued to work until rebooted. Then disaster, no beeps, no video, nothing ... system hanging in POST.
Removed battery and reset CMOS jumpers then rebooted. POST complained of invalid checksum error in CMOS and offered F1 to continue with defaults, or DEL to enter BIOS settings. Selected F1 and system successfully booted and worked perfectly ( but as a XP 1200+ cpu ) but on rebooting it went back to hanging in POST, it needs the CMOS clearing everytime before it will boot with default values. If I select DEL and change the BIOS settings to match the system ( set date/time and select FSB speed ) or even just immediately save and exit the system just hangs in POST and needs CMOS clearing.
Tried using alt-F2 during boot to reflash the bios using the builtin flash utility, and also tried creating a boot diskette and using
AWDFLASH c18d1007.bin /py /sn /cc /cd /cp /wb /e
to reflash to previous bios, in both cases the flashing completed succesfully but the problem still exists.
So at the moment I'm stuck with having to clear cmos using jumpers everytime I power-on or reboot and running with default CMOS parms.
Any ideas on anything else I could try ......... dont fancy the "hot-swap" bios reflashing technique suggested on several sites I'd just stuff up 2 machines or electrocute myself !
