Enable Master

This setting allows you to enable the selected device as the PCI bus master. The options are Enabled and Disabled.

Latency Timer

This setting allows you to set the clock rate for Bus Master. A high-priority, high- throughout device may benefit from a greater clock rate. The options are Default, 0020h, 0040h, 0060h, 0080h, 00A0h, 00C0h, and 00E0h. For Unix, Novell 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.

Large Disk Access Mode

This setting determines the size of a hard drive to be accessed by the user. The options are DOS or Other (for Unix, Novelle NetWare and other operating systems).
