BIOS Setup 3-5
The Hyper-Threading Technology helps your PC work more efficiently by maximizing processor
resources and enabling a single processor to run two separate threads of software simultaneously,
bringing forth greater performance and system responsiveness when running multiple applications at
once.
First Boot Device / Second Boot Device / Third Boot Device / Boot Other Device:
Select the drive to boot first, second and third in the [First Boot Device], [Second Boot Device], and
[Third Boot Device] items respectively. The BIOS will boot the operating system according to the
sequence of the drive selected. Set [Boot Other Device] to [Enabled] if you wish to boot from another
device other than these three items.
Swap Floppy Drive:
When set to [Enabled], and the system is booting from the floppy drive, the system will boot from drive B
instead of the regular drive A. There must be two floppy drives connected in the system to use this
function.
Boot Up Floppy Seek:
When set to [Enabled], the BIOS will check whether the floppy disk drive is installed or not.
Boot Up NumLock Status:
This item determines the default state of the numeric keypad at system booting up.
[On]: The numeric keypad functions as number keys.
[Off]: The numeric keypad functions as arrow keys.
Security Option:
This item determines when the system will prompt for password - every time the system boots or only
when enters the BIOS setup.
[Setup]: The password is required only when accessing the BIOS Setup.
[System]: The password is required each time the computer boots up.
NOTE: Don't forget your password. If you forget the password, you will have to open the computer case
and clear all information in the CMOS before you can start up the system. But by doing this, you will
have to reset all previously set options.
MPS Version Ctrl For OS:
This item specifies which version of MPS (Multi-Processor Specification) this motherboard will use.
Leave this item to its default setting.

This item allows you to access the memory that is over 64MB in OS/2. Leave this item to its default
[Non-OS2] setting for operating system other than OS/2.
Disable Unused PCI Clock:
This option disables the clock of PCI slot that is not in use.
