    Hi,

    I've got an EPoX board with a HighPoint ATA/100 RAID controller. There
    is available an exact same board with a HighPoint RAID controller but
    ATA/133 instead. I'm wondering what the difference is (I mean in terms of
    hardware/software, not functionality). How exactly do the two differ? Do
    the controllers have different hardware? software? bios? something else?
    What I'm driving at here is, can I patch the 100 mb's bios with the bios for
    the 133 mb's bios to upgrade? Can I update the controller bios (using
    CBROM)? If it's just a software thing and the controller hardware is the
    same, it would stand to reason that it can be done correct?


    Thanks.

    Different line drivers. Likely faster and more precise. The 133MHz
    chips may also be selected 100MHz ones, making all/most 100MHZ chips
    unsuitable for 133MHz!
    The hardware is not the same. Even if the BIOS works, you
    will get degraded reliability. In an extreme case you hardware might
    live shorter, since at 133 MHz the line drivers have to drive 1.7 times
    the load they have to drive at 100MHz. Might overheat thechip and bring
    its lifetime down to a few months. However I think the risk of this
    happening is relatively small.
