2-18 Chapter 2: BIOS information
Onboard VGA Shared Memory [8 MB]
This item allows selection of the size of memory shared to the onboard VGA.
Configuration options: [1 MB] [8 MB]
NTSC/PAL Preference [NTSC]
This item allows selection of the TV output standard. Configuration options:
[NTSC] [PAL]
Graphics Aperture Size [128MB]
This feature allows you to select the size of mapped memory for AGP graphic data.
Configuration options: [128MB] [256MB]
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 keep the default [4X
Mode] even if you are using an AGP 1X 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 4X card. Configuration options: [1X Mode] [4X Mode]
Video Memory Cache Mode [UC]
USWC (uncacheable, speculative write combining) is a new cache technology for
the video memory of the processor. It can greatly improve the display speed by
caching the display data. You must set this to UC (uncacheable) if your display
card does not support this feature, otherwise the system may not boot.
Configuration options: [UC] [USWC]
Memory Hole At 15M-16M [Disabled]
This field allows you to reserve an address space for ISA expansion cards. Setting
the address space to a particular setting makes that memory space unavailable to
other system components. Expansion cards can only access memory up to 16MB.
Configuration options: [Disabled] [Enabled]
Delay Transaction [Enabled]
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: [Disabled] [Enabled]
The items Onboard VGA Shared Memory and NTXC/PAL Preference appear
only when the onboard VGA is used.
Onboard VGA [Auto]
When set to Auto, this item allows BIOS to automatically detect the onboard VGA,
and the AGP device if installed. Under this setting, the AGP device has higher
priority over the onboard VGA. If an AGP device is present, the onboard VGA is
disabled. If no AGP device is detected, the onboard VGA is automatically enabled.
When set to Enabled, the onboard VGA is used even if an AGP device is present.
Configuration options: [Auto] [Enabled]
