| == Q: flashrom doesn't seem to work on my board, what can I do? ==
| | {{#externalredirect: https://www.flashrom.org/user_docs/misc_notes.html }} |
| | |
| * 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 [[Board Testing HOWTO#Flashrom|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.
| |
| | |
| * [http://www.coreboot.org/pipermail/coreboot/2008-December/043708.html Please check that your kernel doesn't have CONFIG_STRICT_DEVMEM set, as it will stop flashrom from working.]
| |
| | |
| * [http://www.coreboot.org/pipermail/coreboot/2008-December/043497.html Another poster reported that CONFIG_X86_PAT will also stop flashrom from working. Please try booting with the nopat kernel parameter to temporarily disable it.]

| == Q: How do I use flashrom? ==
| |
| | |
| Please see the [http://flashrom.org/trac/flashrom/browser/trunk/flashrom.8 flashrom(8)] manpage.

| == Q: Is there a flashrom Live CD? ==
