Computer Setup Continued Heading Option Description Advanced* (continued) Bus Options Allows you to enable or disable: • PCI bus mastering, which allows a PCI device to take control of the PCI bus • PCI VGA palette snooping, which sets the VGA palette snooping bit in PCI configuration space; this is only needed with more than one graphics controller installed • PCI SERR# Generation. Device Options Allows you to set: • Printer mode (bi-directional, EPP & ECP, output only) • Num Lock state at power-on (off/on) • PME (power management event) wakeup events (enable/disable) • Processor cache (enable/disable) • Processor Number (enable/disable) for Pentium III processors. • ACPI S3 support (enable/disable). S3 is an ACPI (advanced configuration and power interface) sleep state that some add-in hardware options may not support. • AGP Aperture size (options vary depending on platform) allows you to modify the size of your AGP aperture size window. PCI VGA Configuration Appears only if there are multiple PCI video adapters in the system. Allows users to specify which VGA controller will be the "boot" or primary VGA controller. Support for Computer Setup options may vary depending on your specific hardware configuration. * These options should be used by advanced users only. B-14 Computer Setup

palette snooping bit in PCI configuration space;
this is only needed with more than one graphics
controller installed
•
PCI SERR# Generation.
Device Options
Allows you to set:
•
Printer mode (bi-directional, EPP & ECP, output
only)
•
Num Lock state at power-on (off/on)
•
PME (power management event) wakeup
