Problem with Uniflash and Abit KT7A rev. 1.3

Uniflash cannot access the flash chip (Winbond W49F002U) on a KT7A rev 1.3
Tried with v. 1.33 and 1.32, also tried the -force option - no luck. Flashing works fine with awdflash v 8.22A

It does not like some Abit boards... I have KT7A here but I don't know if it works as I have no Socket A CPU

Any idea why?
Is there a chance to get it working?

They often use GPO (General Purpose Output) of the chipset as additional write-protection.
Starting with UniFlash v1.34 (not released yet), there will be support for detecting boards according to the Award BIOS ID. Boards which use these undocumented methods can be added to UniFlash provided that someone can hack the write protection (the first supported board is MSI MS-6337 v3.0).

Thank you, Rainbow.
I guess I try to figure out the write protection mechanism then...

It was easy on that MSI board. I wrote a small program that wrote the GPO status to a file. Then I rand awdflash and used it to backup current BIOS. Then I ran my program again and compared the files. Only one byte was different. And only one bit in that byte. Awdflash obviously "forgot" to restore that bit after backup
