CHAPTER 3

SDRAM Speculative Read

The settings are enable or disable. If you only use One Bank for

SDRAM and there's no EDO or FP mixed together, the setting is Enable. If

two banks are used by SDRAM, it will automatically be set to disable. The

default setting is enable.

System BIOS Cacheable

By choosing Disabled (default) the system BIOS will be shadowed

into DRAM only. Enabled will have the system BIOS shadowed and

cacheable.

Video RAM Cacheable

Same as system BIOS Cacheable

8-bit I/O recovery time: 1/2/3/4/5/6/7/NA

16-bit I/O recovery time: 1/2/3/NA

Choose the recovery time for 8-bit and 16-bit I/O cycles

respectively.

Note:

NA is not available and so the recovery time of 3.5 SYSCLK will be

inserted.

Memory Hole At 15M-16M

Choosing Enabled will enable a memory hole in the DRAM space.

The CPU cycle matching the enabled hole will be passed on to the PCI. PCI

cycles matching an enabled hole are ignored. Disabled (default) will disable

this function.

Note:

A selected (Enabled) hole is not remapped.

PCI 2.1 Compliance

The Settings are Enable or Disable. During Enable, those PCI add-

on cards with PCI 2.1 compliance will perform better. But some PCI card

does not meet PCI 2.1 compliance, so the default setting is Disabled.
