Q: flashrom doesn't seem to work on my board, what can I do?
- First of all, check if your chipset, ROM chip, and mainboard are supported (see tables above, or use flashrom -L).
- If your board has a jumper for BIOS flash protection (check the manual), disable it.
- Should your BIOS menu have a BIOS flash protection option, disable it.
- If you run flashrom on a Linux system with kernels >= 2.6.27 there are two issues you have to check:
- See next question: X86_PAT and nopat
- See next question: CONFIG_STRICT_DEVMEM
- See this page for instructions on how to test flashrom support properly (this may be risky, make sure you have a working backup flash chip).
Q: I get 'Can't mmap memory using /dev/mem: Invalid argument
- The easiest fix is to update to latest flashrom from svn. It has less strict requirements and works on more systems without having to change the kernel.
Q: How do I use flashrom?
Please see the flashrom(8) manpage.
Q: Is there a flashrom Live CD?
See Flashrom/Live CD.
