4. BIOS Setup
4.4.11 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.
4.4.12 Gate A20 Option
This entry allows you to select how the gate A20 is handled. The gate A20 is a device used
to address memory above 1 Megabytes. Initially, the gate A20 was handled via a pin on the
keyboard. Today, while keyboards still support this function, it is more common and much
faster that the system chipset supports.
4.4.13 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 a\rate and typematic delay.
4.4.14 Typematic Rate (Chars/Sec)
When the typematic rate setting is enabled, you can select a typematic rate (the rate at which
character repeats when you hold down a key) of 6,8,10,12,15,20,24, or 30 characters per
second.
4.4.15 Typematic Delay (Msec)
When the typematic rate setting is enabled, you can select a typematic delay (the delay
before keystrokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
4.4.16 Security Option
If you have set a password, select whether the password is required every time the System
boots, or only when you enter Setup.
4.4.17 OS Select for DRAM>64MB
Select OS2 only if you are running OS/2 operating system with greater than 64MB of RAM
on your system.
4.4.18 Shadow
Software that resides in a read-only memory (ROM) chip on a device is called firmware. The
Award BIOS permits shadowing of firmware such as the system BIOS, video BIOS, and
similar operating instructions that come with some expansion peripherals, such as, for
example, a SCSI adaptor.
