You may want to change your assumptions about what can and can't be. ;) And I can definitely say that if you don't allow access to these "extended" VGA ports, BIOSes either enter infinite loops or else terminate without initialising the card. Trust me; I've been successfully running various PCI VGA card BIOSes under an x86 emulator on an ARM machine for the past few months. _____ |_____| ------------------------------------------------- ---+---+- | | Russell King rmk@arm.linux.org.uk --- --- | | | | http://www.arm.linux.org.uk/personal/aboutme.html / / | | +-+-+ --- -+- / | THE developer of ARM Linux |+| /|\ / | | | --- | +-+-+ ------------------------------------------------- /\\\ | - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
