If BIOS is often correct: Is it possible to read these values and compare them to the values linux calculates? If both match: OK, continue.

Just an idea, I don't know anything about chipsets and IDE timings ;-) Jan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
