BootUp Sequence
The option determines where the system looks first for an operating system.
BootUp Num-Lock
This item is used to activate the Num-Lock function upon system boot. If the setting is on, after a boot, the Num-
Lock light is lit, and user can use the number key.
Floppy Drive Swap
The option reverses the drive letter assignments of your floppy disk drives in the Swap A, B setting, otherwise
leave on the default setting of Disabled (No Swap). This works separately from the BIOS Features floppy disk
swap feature. It is functionally the same as physically interchanging the connectors of the floppy disk drives. When
the setting is <Enabled>, the BIOS will be swapped floppy drive assignments so that Drive A becomes Drive B,
and Drive B becomes Drive A under DOS.
Floppy Drive Seek
If the item is setting Enabled, the BIOS will seek the floppy drive one time upon bootup.
Mouse Support
The setting of Enabled allows the system to detect a PS/2 mouse on bootup. If detected, IRQ12 will be used for
the PS/2 mouse. IRQ 12 will be reserved for expansion cards if a PS/2 mouse is not detected. Disabled will
reserve IRQ12 for expansion cards and therefore the PS/2 mouse will not function.
Typematic Rate
This item specifies the speed at which a keyboard keystroke is repeated.
