BIOS Setup

Precharge Delay

The field specifies the idle cycles before precharging an idle bank.

Settings: [8], [7], [6], [5] (clocks).

Burst Length

This setting allows you to set the size of Burst-Length for DRAM.

Bursting feature is a technique that DRAM itself predicts the ad-

dress of the next memory location to be accessed after the first

address is accessed. To use the feature, you need to define the

burst length, which is the actual length of burst plus the starting

address and allows internal address counter to properly generate

the next memory location. The bigger the size, the faster the

DRAM performance. Settings: [4], [8].

AGP Aperture Size (MB)

This setting controls just how much system RAM can be allocated to

AGP for video purposes. The aperture is a portion of the PCI memory

address range dedicated to graphics memory address space. Host cycles

that hit the aperture range are forwarded to the AGP without any

translation. The option allows the selection of an aperture size of [4MB],

[8MB], [16MB], [32MB], [64MB], [128MB], and [256MB].

VGA Share Memory Size

The system shares memory to the onboard VGA card. This setting con-

trols the exact memory size shared to the VGA card. Setting options:

[1M], [4M], [8M], [16M], [32M].
