Chapter 239 BIOS Setup Utility The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/ Output System). Your computer is already properly configured and optimi zed, and you do not need to run this utility. However, if you encounter configuration problems, you may need to run Setup. Please also refer to Chapter 4 Troubleshooting when problem arises. To activate the BIOS Utility, press m during POST (when “Press to enter Setup” message is prompted on the bottom of screen).

Follow these instructions: TTo choose a menu, use the cursor left/right keys ( zx). System Utilities Chapter 2 SG_TM420_Ch2.fm Page 39 Thursday, September 26, 2002 9:40 AM
40Chapter 2 TTo choose a parameter, use the cursor up/down keys ( wy). TTo change the value of a parameter, press p or q. TPress ^ while you are in any of the menu options to go to the Exit menu. TIn any menu, you can load default settings by pressing t. You can also press u to save any changes made and exit the BIOS Setup Utility. NOTE: You can change the value of a parameter if it is enclosed in square brackets. Navigation keys for a particular menu are shown on the bottom of the scr een. Help for parameters are found in the Item Specific Help part of the screen. Read this ca refully when making changes to parameter values. SG_TM420_Ch2.fm Page 40 Thursday, September 26, 2002 9:40 AM
Chapter 241 Info. This menu provides you the information of the system. ParameterDescription Floppy Drive The Floppy Drive status is auto detected by the system. The information page would display “1.44MB, 3 1/2 if floppy drive exists; it would disp lay “Not installed” if floppy drive does not exist. IDE1 Model Name Shows the Model name of HDD inst alled on Primary IDE master. The system will auto detect the hard disk model name. “None” means the hard disk drive is not existing or unknown type. IDE1 Serial Number This item displays the Model Na me of HDD installed on Primary IDE master. If no hard disk or other devices are installed on Primar y IDE master, this item will display a blank line. IDE2 Model Name Displays the Model Name of Device installed on Secondary IDE master. The hard disk or CD-ROM model is automatically detected by the system. If the hard disk drive or CD-ROM is not existing or unknown type, this field would display “None”. IDE2 Serial Number This field shows the Serial Num ber of HDD installed on Secondary IDE master. If no hard disk drive or other devices are installed on Pr imary IDE master, it will display a blank line. System BIOS Version Displays system BIOS version VGA BIOS Version Displays VGA BIOS version Serial Number Displays the serial number of the unit.
