Latency Timer
This setting allows you to set the clock rate for the bus master. A high-priority,
high-throughout device may benet from a greater clock rate. The options are
Default, 0020h, 0040h, 0060h, 0080h, 00A0h, 00C0h, and 00E0h. For Unix,
Novelle and other Operating Systems, please select the option: other. If a drive
fails after the installation of a new software, you might want to change this setting
and try again. A different OS requires a different bus master clock rate.
