85DIV / 85DIV-L Chapter 4 BIOS Setup THE BIOS BIOS stands for Basic Input and Output System. It was once called ROM BIOS when it was stored in a Read-Only Memory(ROM) chip Now manufacturers would like to store BIOS in EEPROM which means Electrically Erasable Programmable Memory.
Chapter 4 BIOS Setup 4-1 About BIOS Setup BIOS setup is an interactive BIOS program that you need to run when: 1. Changing the hardware of your system. (For example: installing a new Hard Disk etc.) 2. Modifying the behavior of your computer. (For example: changing the system time or date, or turning special features on or off etc.) 3.
85DIV / 85DIV-L 4-5 To Upgrade BIOS • System BIOS is incorporated into a Flash memory component. Flash BIOS allows user to upgrade BIOS without the need to replace an EPROM component. • The Upgrade Utility can be loaded on a floppy diskette to execute saving, verifying, and updating the system BIOS.
