4. BIOS SETUP

SDRAM Active to Precharge Time [6T]

To make changes to this field, set the SDRAM Configuration field to
[User Defined]. Configuration options: [6T] [5T]A7V

Bank Interleave [Auto]

Configuration options: [None] [2 Banks] [4 Banks] [Auto]

DRAM 4K/8K Page Enable [Auto]

Configuration options: [Auto] [4K page enable] [8K page enable]

DDR_1T/2T_ITEM [2T CMD]

Configuration options: [1T CMD] [2T CMD] [Auto Mode]

Burst Len [Auto]

The DRAM burst length supports 8QW and 4QW. The default [Auto] detects
the appropriate setting. Configuration options: [Auto] [4]

Read Around Write [Enabled]

Setting this field to [Enabled] allows the memory controller to store write
data in its buffer whenever the CPU issues a write command. The next time
the CPU needs the data, it retrieves the data from the memory buffer without
accessing the SDRAM. Configuration options: [Disabled] [Enabled]

Delayed Transaction [Disabled]

When set to [Enabled], this feature frees the PCI bus when the CPU is
accessing 8-bit ISA cards. This process normally consumes about 50-60
PCI Clocks without PCI delayed transaction. Set this field to [Disabled]
when using ISA cards that are not PCI 2.1 compliant. Configuration options:
[Enabled] [Disabled]

PCI to DRAM Prefetch [Always prefetc]

Configuration options: [Always Prefetch] [Prefetch disabled] [Prefetch only
enhance command]

AGP Capability [4X Mode]

This motherboard supports the AGP 4x interface that transfers video data at
1066MB/s. AGP 4x is backward-compatible, so you may leave the default
[4X Mode] on even if you are using an AGP 1x or 2x video card. When set
to [1X Mode], the AGP interface only provides a peak data throughput of
266MB/s even if you are using an AGP 2x/4x card. When set to [2X Mode],
the AGP interface only provides a peak data throughput of 533MB/s even if
you are using an AGP 4x card. Configuration options: [1X Mode] [2X Mode]
[4X Mode]

AGP Fast Write [Disabled]

Configuration options: [Disabled] [Enabled]
