`Chapter 2
`Configuring the Stylistic ST4000 Tablet PC BIOS
`
`This chapter provides instructions on how to use the Setup Utility to configure the Stylistic ST4000 Tablet PC BIOS.
`Permanent and Current BIOS Settings
`2
`
`Some BIOS configuration utilities allow you to select permanent and/or current settings when configuring BIOS
`options. When you change a permanent setting, BIOS parameters stored in CMOS memory are changed and the new
`setting is applied after the system is restarted. When you change a current setting, BIOS parameters stored in
`dynamic memory are changed and the new setting is applied for the current session. Also, note that a change to the
`current setting only remains in effect until the system is restarted or shut down.
`
`BIOS data resides in the system’s CMOS memory. When the system is powered on, BIOS data is copied or
`“shadowed” into the system’s dynamic memory and the system runs using BIOS parameters stored in dynamic
`memory.
`BIOS Setup Utility
`
`2
`
`The BIOS Setup Utility is a configuration utility that you can use to change your system’s permanent BIOS settings.
`The BIOS Setup Utility application is stored in the BIOS flash ROM. (BIOS Setup values or settings are stored in
`CMOS memory.) Instructions for starting and running BIOS Setup are given in the following discussions.
`Starting BIOS Setup
`
`2
`
`To start BIOS Setup, restart your system and when the following message is displayed,
`
`<F2>, <2-Taps>: BIOS Setup
`
`Press the [Alt] application button (the button closest to the corner of the display) or press [F2] on an external
`keyboard.
`
`The system starts the BIOS Setup Utility and the BIOS Setup Main menu is displayed.
`
`Options and settings for menus in BIOS Setup are described in tables appearing later in this chapter.
