Slot1 PCI-Exp. x8, Slot2 PCI-Exp. x8 and Slot3 PCI-Exp. x4
Access the submenu for each of the settings above to make changes to the
following:
Option ROM Scan
When enabled, this setting will initialize the device expansion ROM. The options
are Enabled and Disabled.
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 benefi t 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

Warning: Use caution when changing the Advanced settings. Incorrect
values entered may cause system malfunction. Also, a very high DRAM
frequency or incorrect DRAM timing may cause system instability. When
this occurs, revert to the default setting.
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.
ECC Conditions (Available when supported by the memory)
