4. BIOS SETUP
Boot Sequence
The original IBM PCs loaded the DOS operating system from drive A (floppy disk).
Because of this, IBM PC-compatible systems are designed to search for an operating
system first on this drive, and then on drive C (hard disk). However, the BIOS now
offers 10 different boot sequence options of three drives each. In addition to the
traditional drives A and C, options include IDE hard drives D, E, and F, as well as an
SCSI hard 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
When “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 720 KB, 1.2
MB, and 1.44 MB 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
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.
Typematic Rate Setting
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 Typematic Delay.
Typematic Rate (Chars/Sec)
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) of 6, 8, 10,12, 15, 20,
24 or 30 characters per second.
Typematic Delay (Msec)
When the “Typematic Rate” setting is “Enabled”, you can select a Typematic Delay,
(the delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
Security Option
If you have set a password, select whether the password is required each time the
System boots, or only when you enter Setup.
PCI/VGA Palette Snoop
Some display cards that are not standard VGA, such as graphics accelerators or MPEG
cards, may not show the correct colors. This setting can correct the problem once it is
set it to “Enabled”. For default setting, leave at “Disabled”.
