EP-MVP3C BIOS ROM Checksum Error. Diskette stops after 2 sec

aarekk · Tue Mar 30, 2004 10:13 am

I have EP-MVP3C EPOC MOBO. My BIOS upgrade failed. (AWDFLASH finished successfully, but after reboot I saw "BIOS ROM Checksum Error" Message and system required system diskette. I prepared bootable system diskette with awdflash.exe, my previous version of BIOS in .bin file, autoexec.bat with proper command to run awdflash. System starts to read from the diskette and after 2 seconds stops. I am sure that there are no bad sectors on the diskette. Thank you for any helpful advices.

Does it boot to DOS if you use a normal DOS boot diskette?

No, it doesn't unfortunately.

You can try to use an old ISA I/O card.

I'll try if I find some. I've already tried to use Caldera DR-Dos boot diskette. I got "Can't load bdos krenel file: A:\IBMDOS.COM System halted." It seems as only the beginning part of dos can be loaded from diskettes...

Did you clear CMOS?

What about trying the AWARDBoot disk that is posted here (somewhere)?

Do you mean the AWDblock utility? It has a bit other purpose.

I'd try another floppy and/or FDD drive.

Yeah...that's it.

I thought it might be able to let him do a bit more diagnostics...assuming his hardware was good prior to the flash...which I have no reason to doubt.
