Description
Virus Warning Dis. Dis. Dis. ; En. When Enabled, occurs a warning message if a program (specifically,
a virus) attempts to write to the boot sector or the partition table of
the hard disk drive. This feature protects only the boot sector, not the
entire hard drive.
Note: Many disk diagnostic programs that access the boot
sector table can trigger the virus warning message. If you plan
to run such a program, we recommend that you first disable the
virus warning.
CPU Internal Cache En. En. Dis. ; En. Enables or Disables the CPU Internal Cache.
External Cache Dis. En. Dis. ; En. Enables or Disables the CPU external Cache.
Quick Power On Self
Test Dis. Dis. Dis. ; En. 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 is better to find
a problem during POST than lose data during your work.

The original IBM PCs load the DOS operating system from drive A
(floppy disks), so IBM PC-compatible systems are designed to
search for an operating system first on drive A, then on drive C (hard
disk). However, modern computers usually load the operating
system from the hard drive, and may even load it from a CD-ROM
drive.
Swap Floppy Drive Dis. Dis. Dis. ; En.
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 Dis. Dis. Dis. ; En. When Enabled, the BIOS tests (seeks) floppy drives to determine
whether they have 40 or 80 tracks. Only 360KB 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.
Boot Up NumLock
Status Off Off On ; Off Toggle between On or 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.
Boot Up System Speed High High Low ; High Select High to boot at the default CPU speed; select Low to boot at
the speed of the AT bus. Some add-in peripherals or old software
(such as old games) may require a slow CPU speed. The default
setting is High.
Typematic Rate Setting Dis. Dis. Dis. ; En. When Disabled, the following two items (Typematic Rate and
Typematic Delay) are irrelevant. Keystrokes repeat at a rate
determined by the keyboard controller in your system. When
Enabled, you can select a typematic rate and a typematic delay.
Typematic Rate
(Chars/Sec) 6 6 6 to 30 char.
per second
When the typematic rate setting is Enabled, you can select a
typematic rate (the rate at which characters repeat when you hold
down a key in a second).
Typematic Delay
(Msec) 250 250 250 ; 500 ; 750
; 1000 ms
When the typematic rate setting is Enabled, you can select a
typematic delay (the delay before key strokes begin to repeat).
Security Option Setup Setup Setup ; System If you have set a password, select whether the password is required
every time the system boots, or only when you enter Setup.
