Chapter 4 BIOS Setup
68 Reference Manual ReadyBoard 800
♦ PS/2 Mouse – [Disabled] or [Enabled]
* If this field is set to [Enabled], then the on-board PS/2 Mouse controller is used and
assigned an IRQ by the BIOS, typically IRQ 12.
* If this field is set to [Disabled], then the on-board PS/2 Mouse controller is not used and
IRQ 12 is available for other devices.
♦ USB – [Disabled], [2 Ports] or [4 Ports]
* If this field is set to [4 Ports], both on-board USB controllers are used, each one
supporting two USB ports.
* If this field is set to [2 Ports], the first on-board USB controller is used, supporting two
USB ports, and the second on-board USB controller is disabled.
♦ Audio – [Disabled] or [Enabled]
* If this field is set to [Enabled], the on-board Audio controller is used.
Video and Flat Panel Options
• On-Board Video
♦ Framebuffer Size – [Disabled], [1MB], [4MB], [8MB], [16MB], or [32MB]
This field specifies the amount of system memory used for the on-board Video Framebuffer.
The amount of memory used for the Framebuffer of the on-board Video controller is
subtracted from the available system memory.
NOTE If the Framebuffer Size field is set to [Disabled], then no video
will be displayed on screen.
♦ AGP Aperture Size – [64MB], [128MB], or [256MB]
This field specifies the size of memory used for the AGP Aperture. The AGP Aperture Size
indicates the amount of system memory that can be used for the 3D engine. The system
memory is still available for the system use, unless an application actually uses the AGP
Aperture memory.
♦ Off-Board Primary – [Disabled] or [Enabled]
This field specifies which video controller is initialized as the primary video controller. This
includes the on-board (ReadyBoard 800) video controller and/or a second video controller
(video card through PCI-104 bus), initialized as the primary and secondary, or primary video
controller only.
* If this field is set to the default setting, [Disabled], the on-board video controller will
always be initialized by the BIOS as the primary video controller. If a second video
controller is present, the OS can initialize this video controller as the secondary video
controller, allowing you to use two separate video controllers and displays.
* If this field is set to, [Enabled], the on-board video controller will not be initialized by the
BIOS, allowing the OS to initialize an off board video controller as the primary controller.
The on-board (ReadyBoard 800) video controller will not be recognized by the OS, and
therefore, will never be initialized as the secondary controller.
♦ Display – [CRT], [LCD], or [CRT + LCD]
This field specifies the display type used.
* If [LCD] or [CRT + LCD] is selected, the panel type selection indicates the configuration
the LCD panel attached. See the next field and Table 4-3.
* If the [CRT+LCD] is selected, the same video information is shown on both displays
simultaneously.
