It's BIOS chips are soldered SOIC-8 ones, so - in addition to a programmer like - you'll need a SOIC-8 test clip to backup the contents of these chips. USB extension cable is also recommended for more convenience. You can do a backup of both chips (BIOS and Intel ME) and then proceed.

Tell us your motherboard model etc, so that we can learn more about the possible recovery options just in case. Maybe you can get a dirt cheap (2 dollar) flashrom-supported programmer like CH341A (green PCB), remove a chip using a PLCC clip, insert to a programmer, backup the contents and then do the experiments you'd like to try - and, if anything goes wrong, you just restore a knowing good image using another computer.

Hi,
I did an attempt just to see if flashing a ROM works on my motherboard before flashing i-PXE rom. I try to backup with command: flashrom -p internal -V -r biosback Then flashing the same backup: flashrom -p internal -V -w biosback No error occurs and after a reboot the system is OK.
I am frightened to destroy entire BIOS while flashing an i-PXE rom on my onboard NIC. The previous mentioned backup is 1,048,576 bytes and seems realy large and may be it contains bios data other than PXE code. I have doubt where the program retrieve and write his data because there is no atheros feature for it.
I want to know if there is any danger to alter the entire BIOS if I flash an i-PXE ROM on my onboard NIC ?
