Tomcat i7221 S5150
This is because OS/2 and Windows enter and leave protected mode via the BIOS, so Gate
A20 needs to switch often from enabled to disabled and back again. Setting this feature to
Fast improves memory access performance above 1MB because the chipset is much faster at
switching Gate A20 than the keyboard controller. It is recommended that you set it to Fast for
faster memory accesses.
Normal / Fast
Typematic Rate Setting
This feature enables you to control the keystroke repeat rate when you d epress a key
continuously. When enabled, you can manually adjust the settings using the two typematic
controls (Typematic Rate and Typematic Delay). If disabled, the BIOS will use the default
setting.
Enabled / Disable d
Typematic Rate (Chars/Sec)
Defines how many characters are repeated per second when holding down a key on the
keyboard:
6 / 8 / 10 / 12 / 15 / 20 / 24 / 30
Typematic Delay (Msec)
Defines the delay (in milli-seconds) that occurs at keystroke before that key will start to repeat.
250 / 500 / 750 / 1000
Security Option
Setting this option to System will set the BIOS to ask for the password each time the system
boots up.
If you choose Setup, then the password is only required for access into the BIOS setup
menus.
