Some more info: tried two flavors of linux CDs with flashrom,

SystemRescueCD: works
GRML: can't enable writing (same as DOS)

Thinking it must have something to do with ACPI, I tried disabling ACPI with SystemRescueCD (tried acpi=off, acpi-off, and noacpi), but it still worked. However, I don't know how to verify that ACPI support was really disabled.

By the way, the master SMI enable can't be disabled; the BIOS locks it. Unless there is a way to generate a PCI reset without rebooting the system...

Thanks,
