Tyan Computer GX21 Normal / Fast, Typematic Rate Setting, Enabled/Disable, Typematic Delay Msec

This is because OS/2 and Windows enter and leave pro- tected 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. The choices are:

Normal / Fast

Typematic Rate Setting

This feature enables you to control the keystroke repeat rate when you depress a key continuously. When enabled, you can manually adjust the settings using the two typematic con- trols (Typematic Rate and Typematic Delay). If disabled, the BIOS will use the default setting. The choices are:

Enabled/Disable

Typematic Rate (Chars/Sec)

This setting defines the number of characters repeated per second when holding down a key on the keyboard. The pos- sible values are:

6 / 8 / 10 / 12 / 15 / 20 / 24 / 30

Typematic Delay (Msec)

This setting defines the delay (in milli-seconds) that occurs at keystroke before the key will start to repeat. The possible val- ues are:

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. The choices are:

Setup / System
