4. BIOS SETUP

Display Cache RAS Precharge Time [2T]

Configuration options: [2T] [3T]

Display Cache Cycle Time (Tras, Trc) [5T, 8T]

Configuration options: [5T, 8T] [7T, 10T]

Display Cache Paging Mode [Page Open Mode] Configuration options: [Page Open Mode] [Page Close Mode]

Video Memory Cache Mode [UC]

USWC (uncacheable, speculative write combining) is a new cache technology for the video memory of the processor. It can greatly improve the display speed by caching the display data. You must set this to UC (uncacheable) if your display card cannot support this feature; otherwise your system may not boot. Configuration options: [UC] [USWC]

Graphics Window Size [64MB]

This feature allows you to select the size of mapped memory for AGP graphic data. Configuration options: [64MB] [32MB]

AGP Capability [4X Mode]

This motherboard supports the AGP 4x interface, which transfers video data at 1066MB/s. Since AGP 4x is backward-compatible, you may leave this on the default setting of [4X Mode] even when you are using an AGP 2x video card. When set to [2X Mode], the AGP interface will only provide a peak data throughput of 533MB/s even if you are using an AGP 4x card. Configuration options: [2X Mode] [4X Mode]

Memory Hole At 15M-16M [Disabled]

This field allows you to reserve an address space for ISA devices that require it. Configuration options: [Disabled] [Enabled]

PCI 2.1 Support [Enabled]

This function allows you to enable or disable PCI 2.1 features including passive release and delayed transaction. Configuration options: [Disabled] [Enabled]

High Priority PCI Mode [Enabled]

This field allows you to give PCI slot 1 a higher priority. You may want to leave on the default setting if you are using an IEEE-1394 PCI card. Configuration options: [Disabled] [Enabled]

Onboard PCI IDE Enable [Both]

You can select to enable the primary IDE channel, secondary IDE channel, both, or disable both channels. Configuration options: [Both] [Disabled]

SDRAM Data Driving Mode [Normal]

Leave on default setting. Configuration options: [Normal] [Strong]
