CAS latency time.
DRAM RAS# to CAS# Delay
This item allows you to select a delay time between the CAS and RAS strobe signals. It only applies when DRAM is written to,
read from, or refreshed. This field is adjustable only when “DRAM Timing Selectable” is set to “manual”. This field is locked
when “DRAM Timing Selectable” is set to “By SPD” and is automatically determined by the system. Options: 4

DRAM RAS# Precharge
This item allows you to select the DRAM RAS# precharge time. The ROW address strobe must precharge again before DRAM
is refreshed. An inadequate configuration may result in incomplete data. This field is adjustable only when “DRAM Timing
Selectable” is set to “
manual
”. This field is locked when “DRAM Timing Selectable” is set to “
By SPD
” and is automatically
determined by the system. Options: 4

MGM Core Frequency
This field sets the frequency of the DRAM memory installed.
The choices : Auto Max 266MHz, 400/266/133/200 MHz , 400/200/100/200 MHz, 400/200/100/133 MHz , 400/266/133/267
MHz,
System BIOS Cacheable
Enabling this function allows caching of the system BIOS ROM at F0000h-FFFFFh, which results in better system performance.
However, if any program writes to this memory area, a system error may result. It is advisable to leave it in default setting.
Caching the system BIOS results in better performance than shadowing the system BIOS.
Video BIOS Cacheable
This feature is only valid when the BIOS is shadowed. It enables or disables the caching of the video BIOS ROM at
C0000h~C7FFFh via the L2 cache. This greatly speeds performance because the OS bypasses the BIOS using the graphics
driver to access the video card’s hardware directly.
On-Chip VGA
This item is enabled as the onboard VGA is used. The Choices: Enable / Disable
On-Chip Frame Buffer Size
This item is to select the amount of system memory that will be utilized as internal graphics device memory
The choices: 1MB, 4MB, 8MB, 16MB, 32MB.
Boot Display
This item is to select the display device that the screen will be shown
The choices: CRT , LFP(LVDS), CRT+LFP(LVDS).
Panel Number
This item is to select the Panel display resolution that will be displayed depending on the LCD panel(LFP)
The choices: 640x480 18 / 800x600 18 / 1024x768 18 / 1280x1024 24x2 / 1400x1050 24 / 1600x1200 24 / 1280x768 24 /
