4. BIOS SETUP

SDRAM MA Wait State [Normal]

This controls the leadoff clocks for CPU read cycles. Leave on default set- ting. Configuration options: [Fast] [Normal] [Slow]

Snoop Ahead [Enabled]

[Enabled] allows PCI streaming. Configuration options: [Enabled] [Disabled]

Host Bus Fast Data Ready [Disabled]

Configuration options: [Disabled] [Enabled]

16-bit I/O Recovery Time [1 BUSCLK]

Configuration options: [4 BUSCLK] [1 BUSCLK] [2 BUSCLK] [3 BUSCLK]

8-bit I/O Recovery Time [1 BUSCLK]

Configuration options: [8 BUSCLK] [1 BUSCLK] [2 BUSCLK] [3 BUSCLK] [4 BUSCLK] [5 BUSCLK] [6 BUSCLK] [7 BUSCLK]

Graphics Aperture Size [64MB]

This feature allows you to select the size of mapped memory for AGP graphic data. Configuration options: [4MB] [8MB] [16MB] [32MB] [64MB] [128MB] [256MB]

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]

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]

Memory Hole At 15M-16M [Disabled]

This field allows you to reserve an address space for ISA expansion cards that require it. 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] [Primary] [Sec- ondary] [Disabled]

Data Integrity Mode [Non-ECC]

[Non-ECC] has byte-wise write capability but no provision for protecting data integrity in the DRAM array. When [EC-Only] is selected, data errors are detected but not corrected. [ECC] with hardware scrubbing allows the detection of single-bit and multiple-bit errors and recovery of single-bit er- rors. This field is available only if your DIMMs have ECC. Configuration options: [Non-ECC] [EC-Only] [ECC]
