I am trying to flash an SST49LF008A on a board with a
southbridge using flashrom. It reads fine, but when I try to write, it
failed with an ERASE FAILED message. Any ideas on why?
Geode systems write protect the BIOS via RCONFs (cache settings similar
to MTRRs). Change MSR 0x1808 top byte to 0x22. Then run flashrom.
MSR register 0x1808 =>
wrmsr 0x1808 22:ff:fc:02:13:f7:df:00
register 0x1808 => 22:ff:fc:02:13:f7:df:00
