BIOS SETUP

DRAM RAS# Precharge

This option sets the number of cycles required for the RAS to accumulate its charge before the SDRAM refreshes. The default setting for the Active to Precharge Delay is 4.

Precharge Delay (tRAS)

The default setting for the Precharge Delay is 12.

System Memory Frequency

The default setting is 533MHz.

SLP_S4# Assertion Width

The default setting is 1 to 2 Sec.

System BIOS Cacheable

The setting of Enabled allows caching of the system BIOS ROM at F000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.

Video BIOS Cacheable

The Setting Enabled allows caching of the video BIOS ROM at C0000h-F7FFFh, resulting in better video performance. However, if any program writes to this memory area, a system error may result.

Memory Hole At 15M-16M

In order to improve performance, certain space in memory can be reserved for ISA cards. This memory must be mapped into the memory space below 16 MB. The choices are Enabled and Disabled.

On-Chip VGA Setting

The fields under the On-Chip VGA Setting and their default settings are: PEG/On Chip VGA Control: Auto

On-Chip Frame Buffer Size: 8MB

DVMT Mode: DVTM

DVMT/Fixed Memory Size: 128MB

SDVO Device Setting: (LVDS, DVI, Dual DVI, CRT)

Remarks: Set to LVDS for ID390, Set to CRT to ID390C, Set to DVI for ID391/ID392/ID391D/ID392D

SDVO LVDS Protocol: 1Ch SPWG, 24bit

SDVO Panel Number: 1024x768

Boot Display: Auto

Panel Scaling: Auto

Panel Number: 1024x768 18 bit SC
