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 Supported hardware, 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:
- TODO: X86_PAT and nopat
- TODO: CONFIG_STRICT_DEVMEM
- If you run flashrom on OpenBSD, you might need to obtain raw access permission by setting securelevel=-1 in /etc/rc.securelevel and rebooting, or rebooting into single user mode.
- 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).
How do I use flashrom?
Please see the flashrom(8) manpage.
Is there a flashrom Live CD?
