Description
Please refer to the table on page 51
to set the DRAM clock.
This option lets you reserve system
memory area for special ISA cards.
The chipset accesses code/data of
these areas from the ISA bus
directly. Normally, these areas are
reserved for memory mapped I/O
cards.
Lets you configure the hard disk
drive connected to the slave port of
IDE channel 2.
Enabling this item allows you to
cache the system BIOS to further
enhance system performance.
This item lets you cache Video RAM
A000 and B000.
If you are not sure which AGP mode
to choose, simply select the highest
AGP mode (4x) available. The
system automatically downgrades
to the proper mode.
This item lets you determine the
effective size of the AGP Graphic
Aperture.
The micro codes are used to fix
bugs of the Pentium III CPU; we
strongly recommend that you
enable this item for system
reliability reasons. However, these
micro codes may slightly reduce
CPU performance. We provide this
option for your convenience if you
would like to test it.
