There is one feature in the ALi busmastering driver that would
be considered unusual in comparision with IBM's driver.  It has
a /CLK statement which is for the PCI bus speed of the motherboard.
Normally, it is 33Mhz.  But you will have to look up your motherboard's
documentation in order to get the most accurate information.  An
example:  AOpen AP59S motherboard lists the following...

 Bus speed of CPU     PCI speed
     60Mhz              30Mhz
     66Mhz              33Mhz
     75Mhz              32Mhz
     75Mhz              37Mhz
     83Mhz              32Mhz
     90Mhz              30Mhz
    100Mhz              33Mhz

  So if I were running my processor at 3x66Mhz (200Mhz) than the
proper setting would be "BASEDEV=ALI.ADD /CLK:33".
