Since "disk geometry" has become such a terrible mess, recent BIOSes decide that they don't know what the geometry should be, and guess the geometry from the partition table, if there is one. So, if you added partitions during the install then it is not impossible that the BIOS changed its mind concerning the geometry. It would be interesting to see the precise partition table (output of "fdisk -l /dev/hda"). - 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/
