I think the flash write enabled, I use this :                         
                                                                      
setpci -s 0:11.0 40.b=54                                              
                                                                      
I've read that this should enable writting, but i'm not sure.         
                                                                      
Here is my flash_rom output:                                          
                                                                      
Calibrating timer since microsleep sucks ... takes a second           
Setting up microsecond timing loop                                    
184M loops per second                                                 
Ok, calibrated, now do the deed

Mine is a 39SF020A (it's written on the chip)
