Odd sort of problem

Question

I have a K8N Neo2 Mobo which stopped working, when the power was turned on at the mains all the fans etc started to run but there was no POST.
After much beating about I got my BIOS chip reflashed Great every thing back to normal, my OS boots up and everything runs as it should BUT,
I cannot enter Setup. Sent the chip back and it tested okay so not the chip or a corrupt BIOS.
When I switch on I get the Platinum boot screen and the options to press TAB for boot menu or DEL for Setup if I key Del all I get is a blank screen and a flashing cursor, if I dont press either TAB or DEL my OS boots normally.
I am at a loss, I have trawled the internet and loads of forums and tech sites but no answer til someone suggested I come here and ask, So I'm asking guys can anyone help me?

Answer 1

This sounds familiar but can't find another reference.
Maybe syar or bosskiller  could help here as I seem to think it is to do with bootblock not being flashed/updated following a bios flash.  Should get resolved with adding switch ("/ wb") to the flash.  Or maybe I'm way off the mark.
You didn't have this problem before the bios flash?
Update:- found this from another thread

It's not possible to only flash the bootblock .
The /wb switch flash the bios and bootblock together with main bios block (it won't skip the blocks you saw earlier).
I'm not saying bootblock is bios layout , i say bootblock change sometimes from one bios version to another
if there is a major bios workover like layout new features etc (or bug fix in the bootblock part of course).
Let me give you an example .
You want all the old parts in old bios updated and all data reset then you use the following switches with an award flash :
AWFL822A W6340VMS.630 /py/sn/wb/cc/cd/cp/f/r
/py - Program flash memory
/sn - say no to create backup bios file
/wb - Program bootblock
/cc - Clear cmos after successful flash
/cd - Clear DMI pool after flash
/cp - Clear PnP/ESCD data after flash
/f - Force programming with the new bios files programming algorythm
/r - reset PC automaticly after flash
This will create a complete new bios flash like the board was delivered from factory with a initial loaded bios 6.3
if using only AWFL822A W6340VMS.630 , you will have no clearing/new dmi pool , preserve old bootblock version , preserve old PnP/ESCD data ,and you will have to
clrear cmos with jumper after flashing.
Could try reflashing with switches above; obviously substitute your flash utility and bios file.
