BIOS SETUP
27
•
CPU L2 Cache ECC Checking
Select “Enabled” to make sure the data is accurate.
•
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. It’s better to find a problem during POST than to lose data during your work.
•
Boot Sequence
The original IBM PCs load the DOS operating system from drive A (floppy disk). So, 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 now offers 11 different boot sequence
options. In addition to the traditional drives “A” and “C”, options include IDE hard drives “D”,
“E”, and “F”; plus a “SCSI” hard drive, a “LS” / “ZIP” drive and a CD-ROM drive.
•
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.
•
Boot Up Floppy Seek
While enabled , the BIOS tests (seeks) floppy drives to determine whether they have 40 or
80 tracks. Because very few modern PCs have 40-track floppy drives (360KB), we
recommand that you set this field to “Disabled” to save time.
•
Boot Up NumLock Status
Toggle between “On” and “Off “to control the state of the NumLock key when the system
boots. When toggled On, the numeric keypad generates numbers instead of controlling
cursor operations.
•
Gate A20 Option
Choose “Fast” (default) or “Normal”. “Fast” allows RAM access above 1MB to use the fast
gate A20 line.
•
Memory Parity / ECC Check
When parity DRAM modules are installed, select “Enabled” to correct 1 bit memory errors
in the memory. Otherwise, select “Disabled”.
