AGP Aperture Size (MB)
Select the size of the AGP (Accelerated Graphics Port) aperture. The aperture is a portion of
the PCI memory address range dedicated for graphics memory address space. Host cycles that
hit the aperture range are forwarded to the AGP without any translation. Options: 4, 8, 16, 32,
64 (default), 128, 256.
On-Chip Frame Buffer Size
Choose the size of the on-chip frame buffer. Options: 1MB, 8MB (default).
PnP/PCI Configurations
Reset Configuration Data
Select “Enabled” to reset the Extended System Configuration Data (ESCD) if you have
installed a new add-on card and the system reconfiguration has caused such a serious conflict
that the OS cannot boot. Options: Disabled (default), Enabled.
Resources Controlled By
BIOS can automatically configure all the boot and Plug and Play compatible devices. If you
choose Auto, you will not be able to manually assign IRQ DMA and memory base address
fields, since BIOS automatically assigns them. Options: Auto <ESCD> (default), Manual.
IRQ Resources
When resources are controlled manually, you can assign each system interrupt a type,
depending on the type of device using the interrupt. This is only configurable when “Resources
Controlled By” is set to “Manual”.

PCI / VGA Palette Snoop
Some graphic controllers that are not VGA compatible take the output from a VGA controller
and map it to their display as a way to provide boot information and VGA compatibility.
Options: Disabled (default), Enabled
PCI Latency Timer (CLK)
This item allows you to set up the PCI Latency Time (0-255). If you select the “32” it will
optimize PCI speeds. Options: 0-255, 32 (default).
PCI SLOT1- 5
This item allows you to select an IRQ address for your PCI slot 1-5. Options: Auto (default), 3,
