Anyone want to speculate why flashram can set the BIOS write enable bit under Linux but not DOS? Is Linux taking over SMI somehow, or is there some BIOS call which permits BIOS writing? Something else?
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...
