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 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,
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 how large hard drives are to be accessed. The options are
DOS or Other (for Unix, Novelle NetWare and other operating systems).
Advanced Chipset Control
Access the submenu to make changes to the following settings.
Warning: Take caution when changing the Advanced settings. An Incor-
rect value, a very high DRAM frequency or an incorrect DRAM timing may
cause system to become unstable. When this occurs, reset the setting to
the default setting.
Accelerate MRC
If Enabled, the BIOS will ignore the Memory Reference Code (MRC) when there
is no change to DIMM population in order to speed up system boot. The options
are Enabled and Disabled.
Clock Spectrum Feature
If Enabled, the BIOS will monitor the level of Electromagnetic Interference caused
by the components and will attempt to decrease the interference whenever needed.
The options are Enabled and Disabled.
Crystal Beach Features

cessor that is installed on an add-on card or a network card to handle some or all
packet processing of this add-on card. For this motherboard, the TOE device is built
inside the ESB 2 South Bridge chip.) The options are Enabled and Disabled.
