Problem with Phoenix Bios Editor

Recommended by Wim's BIOS...

Hi,
Im having problems with Phoenix Bios Editor, the bios is an IBM Firtstbios which I can open no problem but it wont rebuild it. I make a change then reverse it just to activate the build button then rebuild, what I thought would be the same as the input file turns out to be unbootable and totally different.
Im hoping someone has some idea whats going on ?
Cheers
Steve.

IBM customization so no pure PhoenixBios.

Hi Edwin,
Thanks for the reply, any suggestions ?

Contact IBM? I have no idea right now, I don't know what IBM did to the bioses exactly...

IBM are a waste of time, no point in contacting them as I have already found out. Back to the original aproach...see bios rebuild thead.
Cheers
Steve.
