    Hi,

    I would suggest to increase the 8bit waitstates in the BIOS by +1 (or
    more). - you might have to increase the 16bit waitstates as well (or
    instead of the 8bit ones).

    It cured such a problem for me: - A Intel Pentium PC that had run Netware
    3.12 perfectly happily for years didn't boot up with a CRC error after
    installing RedHat 7.0 on it. - Increasing the 8bit waitstates from 1 to 2
    cured the problem completely and the PC is rocksolid now. - The PC also
    ran Windows quite happily (I installed it after the trouble with Linux
    just to see if it would work - I was worried about the hardware having
    gone dodgy.)

    Hope this helps.

    Regards,

            Anton
