bios help

Hello, I recently did a BIOS 'update' since I was having trouble (so I thought) with the previous BIOS.

The Bios I updated to was Halley BIOS version 3.1 (actual board
MSI MS-6340M) from:

click here

But my motherboard was replaced with the same board but was version 5.
See:

Since updating the BIOS I keep getting:
' CMOS Checksum Bad
F2 to Return Setup
F1 to load default values and continue'

I get into Bios and save changes but once I restart I get the above again and computer goes back to bios.

I have cleared the CMOS numerous times by changing the jumper settings and back, changed the CMOS battery to a new one as well leaving it out overnight.

But it still makes no difference.

Also I get ( when I change jumpers and back - to reset CMOS and get into BIOS and changes settings):

' Boot Failure
Insert BOOT diskette in A
Press any key when ready'

When I press any key, I get the above back: the floppy doesn't read;

Further I have no IRQ 6 in the bios menu therefore I conclude this is the reason floppy isn't reading. I'm trying to reflash the bios to the msi version (as above) which will work.


When I restart my pc it automatically goes back into BIOS (so long as I don't reset CMOS).
But when I do clear the cmos I get the checksum bad etc and the above problems again and again.

Can someone please give me a remedy. The bios chip is not faulty; i'm sure of that.

Thanks.

PS: thier is no BIOS recovery jumper for my motherboard since it is ver 5; althought there was one for Ver 3.

Also I can't hot flash since the bios is soldered onto the motherboard.

Silly question, have you checked the battery?

I've put in a new battery.
