    Question grub sees only 4 gig

    I got a 450 GB hard drive from which fedora boots from.
    However when i look at grub,
    grub> geometry(hd0,0)
    and do the cylinder/head/sector math, it only comes to 4GB instead of 450gig.
    Any idea why it sees only 4G?

    Cheers
    David

    This is the CHS geometry reported by the BIOS.
    The BIOS CHS scheme is inadequate to correctly
    describe a modern hard drive. Computers work around this
    limitation, but CHS lives on as a legacy.
