Lane, Geode systems write protect the BIOS via RCONFs (cache settings similar to MTRRs). Change MSR 0x1808 top byte to 0x22. Then run flashrom. > rdmsr 0x1808 MSR register 0x1808 => 25:ff:fc:02:13:f7:df:00 > wrmsr 0x1808 22:ff:fc:02:13:f7:df:00 MSR register 0x1808 => 22:ff:fc:02:13:f7:df:00 Marc -- Marc Jones Senior Firmware Engineer (970) 226-9684 Office mailto:[EMAIL PROTECTED] http://www.amd.com/embeddedprocessors -- linuxbios mailing list [email protected] http://www.linuxbios.org/mailman/listinfo/linuxbios
