[LinuxBIOS] Questions to flashing BIOS chips

I'm new to BIOS-flashing and have some questions and hopefully you can 
help me out. I got a Galep5 programmer with a DIL32 to PLCC32 Adapter 
and samples of some flash-memory chips SST 49LF004B (33-4C-NHE). These 
samples are from Gneral Software Inc. and Insyde Software. I backup the 
original BIOS to files and delete the chip after that I wrote my 
linuxbios.rom to the chip(s) and put it to the motherboard (AMD LX 
DB800), but nothing happen.
After that I wrote the original BIOS back to the chip (compare shown ok) 
and put these into the MB but nothing happen (again).
The MB is ok (I tested with other samples).
Now my question: Its possible these samples have some "protection" 
against use with other BIOS (linuxbios :-) ) or how can I find the error?

Thanx for answers. Thomas
