• CPU Internal Cache / 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 accessed by the CPU. The "External Cache" field may not appear if your system does

not have external cache memory.

• 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. We recommend that you normally disable

Quick POST. It's 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 BIOS attempts to load the operating

system from the devices in the sequence selected in these fields. In addition to the traditional

drives A ("Floppy") and C ("HDD-0"), options include "HDD-1", "HDD-2", "HDD-3", and "CD-

ROM"; a "SCSI" bootable device, a "LS/ZIP" 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.

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 it's useless in

OS/2.

When you select "Enabled", the BIOS tests (seeks) floppy drives to determine whether

they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720KB,

1.2MB, and 1.44MB capacity all have 80 tracks. Because very few modern PCs have 40-

track floppy drives, we recommend that you set this field to "Disabled" to save time.
