Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!


This board is currently not supported, but I am working on it.

Original BIOS information gathering

Dump of the output of the the lbsysinfo tool: File:Asrock fm2a88m-hd+ lbsysinfo.txt.bz2

The dump of the SPI flashrom contents is mostly identical to the "Instant Flash" BIOS update file, if you cut off the first 4kB of the file. The differences seem to be mostly configuration data and settings stored in the flash. There are only a few bytes, which seem to be some kind of serial number or so.
