TMP 255-MG Bios Unlock

Hi All,

I'm going to slic this bios and also want to use AMIDEDOS.EXE on my machine for some reason but can not do this. Whenever i try to save bios or use AMIDEDOS i got error messages.

I think this bios is write protected and i can't disable this option via bios setup menu; there is no button or selection to do this.

Can you help me?

Here is the bios link
