Chapter 4: BIOS

Slot1 PCI-Exp x8

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 a hard drive is 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. Incorrect values entered may cause system to malfunction. Also, a very high DRAM frequency or incorrect DRAM timing may cause system to become unstable. When this occurs, revert the item to the default setting.

SERR Signal Condition

This setting specifi es the ECC Error conditions that an SERR# is to be asserted. The options are None, Single Bit, Multiple Bit, and Both.

4GB PCI Hole Granularity

This feature allows you to specify the size of PCI hole granularity for a PCI slot. If MTRRs are not enough, this option may be used to reduce MTRR occupation. The options are: 256 MB, 512 MB, 1GB and 2GB.
