Looking at the ICH4 data sheet, an SMI interrupt is generated when you enable BIOS writing.

Does flashrom-DOS disable SMI? If not, then the BIOS is probably resetting the bit.

It should disable SMI, yes; I don't see why the cross compiled build wouldn't.
It is the same code that is being compiled: see http://www.flashrom.org/trac/flashrom/browser/trunk/README#L97

(Under Linux the BIOS write enable bit is already set).

Perhaps linux handles SMI "I/O" (I couldn't think of a better name) better dan DOS does ?

Thanks,
Dan
