    # CONFIG_X86_SPEEDSTEP_ICH is not set
    # CONFIG_X86_SPEEDSTEP_SMI is not set
    now it works fine.

    the dell bios detects the disc as */16/63. However the
    partition table is created with */255/63 in mind.
    most bios allow to set the geometry manually or change
    the large/lba/normal mode. the dell bios does not.

    Linux boots fine without the hda= setting, as it only
    uses start and length values. But other tools might have
    problems (grub? *fdisk?).

    Also I used to use drive image / dos version with network stack
    for duplicating discs. and drive image only worked with win
    and linux partitions, if the emulation geometry was */255/63.
    Not sure why. But because of that all blank discs are created
    with */255/63 tables. all other machines I know can be configured
    via that large/lba/normale mode setting, or simply read the partition
    table and automatically adjust to the geometry found.

    Ah, live would be so much easier without chs geometries.

    Is there any tool that will change chs begin/end values
    from */255/63 geometry to */16/63 geometry?

    /dev/discs/disc0/part1 : start= 63, size= 112392, Id=83, b
    /dev/discs/disc0/part2 : start= 2216970, size= 36853110, Id=83
    /dev/discs/disc0/part3 : start= 112455, size= 2104515, Id=82

    x/16/63 world:
    0/1/1 - 111/8/63, 111/9/1 - 2199/5/63, 2199/6/1 - 38759/15/63

    y/255/63 world:
    0/1/1 - 6/254/63, 7/0/0 - 137/254/63, 138/0/1 - 2431/254/63

    maybe there is still some software out there, that will not like
    partitions beginning on something different then */0/1 or
    */1/1. I rather not change the partition table to */16/63
    fake geometry.

    I could backup everything, null the partition table, create a
    new one with */16/63 chs geometry and restore all data.
    but for now using hda= to set the fake geometry works fine.
