BIOS SETUP

CPU Internal/External Cache
Cache memory is additional memory that is much faster than conventional DRAM (system
memory). CPUs from 486-type and up contain internal cache memory. Most, but not all,
modern PCs 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
Select “Enabled” to make sure the data are accurate.
•
Quick Power On Self Test
Select “Enabled” to reduce the amount of time required to run the Power On Self Test
(POST). The Quick POST skips certain steps; therefore, we recommend that you
normally disable Quick POST. It is better to find a problem during POST than to lose
data during your work.
•
First/Second/Third Boot Device; Boot Other Device
The original IBM PCs loaded the DOS operating system from drive A (floppy disk).
Therefore, IBM PC-compatible systems are designed to search for an operating system
first on drive A, and then on drive C (hard disk). However, the selections in these fields
will determine the sequence that BIOS will follow in attempting to load the operating
system from the system’s devices. In addition to the traditional drives A (“Floppy”) and
C (“HDD-0”), options include: “LS120”, a “SCSI” bootable device, “CD-ROM”, “HDD-1”,
“HDD-2”, “HDD-3”, a “ZIP100” drive, and a “LAN” drive. If your bootable device is not
included in the list, you can set the “Boot Other Device” field to “Enabled”, and let the
system detect the drive automatically.
•
Swap Floppy Drive
This field is effective only in systems with two floppy drives. Selecting “Enabled” assigns
physical drive B to logical drive A, and physical drive A to logical drive B. But this item
is useless in OS/2.
