BIOS
Digital Device Priority
Use this option to prioritize the type(s) of display device on your system.
The settings are CRT/FP/TV, FP/CRT/TV, CRT/TV/FP, TV/CRT/FP, FP/TV/CRT
and TV/FP/CRT. (FP stands for flat panel.)
AGP Graphics Aperture Size
This option allows you to adjust the graphics aperture size to either 64 MB
or 32 MB.
Init Display Cache Memory
This option allows the Initial Display cache memory to be adjusted. The
setting are Enabled and Disabled.
Paging Mode Control
This option allows the paging mode controls to be adjusted to either
Close or Open.
RAS-to-CAS Latency Override
The RAS-to-CAS Override is adjusted with this option. The settings
are Disabled and Enabled. Disabled: This option allows RAS-to-CAS.
Enabled: This option overrides RAS-to-CAS. SDRAM stores informa
tion in blocks of rows and columns. RAS stands for Row Address
Strobe. CAS stands for Column Address Strobe.
CAS Latency
This option regulates the speed of the Column Address Strobe (CAS)
as either Fast or Slow, which is higher or lower latency. CAS latency
optimizes the speed at which data is accessed in a column by defining
CAS latency time in 100 MHz or 133 MHz clocks (dependent on the
memory bus speed). It controls the time delay (in clocks) before
SDRAM starts a read command after receiving it. Reading RAS data
can be read twice as fast as reading CAS. Lowering the latency can
increase the speed of the SDRAM, but at the expense of stability.
