MS-6702 (K8t neo) Flashed but now nothing, bios recovery doesn't work!!

Question

 
I updated my bios to the latest one a few weeks back and have been having problems with setting my apeture size to 256 (Noticed a few other people have too here!)
So I reverted the bios back to the one before which I never had any problems with and now my board appears dead 
I get no post screen and the optical drives all constantly seek for some strange reason, I've since unattached everything apart from my agp card, ram, processor and floppy drive in a bid to get bios recovery to work. Sadly it doesn't even try to read the floppy and just sits there feeling sorry for itself.
The LED bracket stays at 4 red lights but nothing else happens. I've had this rig for over 5 months so I know it's not the components before anyone suggests it.
This is doing my head in, thanks MSI firstly for releasing a buggy bios and secondly for killing my board
PLEASE HELP

Answer 1

Have you tried clearing CMOS?
If that doesn't work your board is probably beyond recall.  You have two choices:
1. Try to RMA it to MSI or your vendor.
2. Replace the BIOS chip
I have used (2) on several occasions with other vendor's systems.  This works if the chip is socketed.  I use BIOSFLASH.COM (http://biosflash.com/) - you have to ID your chip, tell them what you have, pay some money and e-mail them a copy of the binary you want programmed.  They have a well-documented procedure on their website.
I would recommend getting at least two chips - one known good and one with the latest BIOS.  That way you can recover from another problem like this one.
Looking at the example K8T Neo2 ATX board on MSI's site the BIOS is socketed but that may not be true of yours.  I have a K8MM-ILSR with a soldered BIOS here, so not all their BIOS chips are socketed.
BTW, which method of flashing did you use?  From DOS, I hope...running a BIOS flash from Windows is a recipe for disaster (that's why I know about BIOSFLASH.COM)
