4.5 BIOS Features Setup
This screen contains industry-standard options additional to the core PC AT BIOS. This
section describes all fields presented by Award Software in this screen. The example
screen below may vary somewhat from the one in your Setup program; your system
board designer may omit or modify some fields
Figure 4-3: BIOS Features Setup — Screen Display
CPU Internal Cache / External Cache
Cache memory is additional memory that is much faster than conventional DRAM
(system memory). CPU’s from 486-type on up contain internal cache memory, and
most, but not all, modern PC’s have additional (external) cache memory. When the CPU
requests data, the system transfers the requested data from the main DRAM into cache
memory, for even faster access by the CPU.
The External Cache field may not appear if your system does not have external cache
memory.
CPU L2 Cache ECC Checking
When you select Enabled, memory checking is enabled when the external cache
contains ECC SRAM’s.
Quick Power-on Self Test
Select Enabled to reduce the amount of time required to run the power-on self-test
(POST). A quick POST skips certain steps. We recommend that you normally disable
quick POST. Better to find a problem during POST than lose data during your work.
