BIOS Configuration

Video RAM Cacheable

Increases video performance by caching video memory.

AGP Aperture Size

Select the size of the Accelerated Graphics Port (AGP) 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. See www.agpforum.org for AGP information.

AGP Driving Control

Due to the compatibility of some AGP cards with the chipset this setting is used to fine tune these issues. Default is set to Manual.

AGP Driving Value

This is the value set for the AGP Driving control. The manufacturers recom- mended setting is set to CC and it is suggested not to change this value.

AGP-4xMode

Enables the 4X AGP mode for higher AGP throughput. A 4X AGP graphics card is required to enable this function.

Due to Tyan’s commitment to advanced technologies and first to market, not all high performance 4X AGP graphics cards are compatible w/ our S1854 at the time of print, please go to our web site for the latest update.

OnChip USB

The chipset contains an integrated USB controller. Select Enabled if you have USB peripherals.

USB Keyboard Support

This function enables the use of a USB Keyboard. Default is Disabled.

Auto Detect DIMM/PC2 CLK

This function enables the BIOS to auto-detect the speed of the DIMM.

CPU Clock/Spread Spectrum

This function allows you to change the CPU clock frequency and to Enable/ Disable the Spread Spectrum function which lowers EMI levels.
