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,
Dan
