When it’s not easy to slide the CF card into the socket, you need to flip the CF card over and try again. 7. Use a screw tool to push the CF card inward to make sure a tight connection between CF card and socket. Warning: Be careful not to touch and push any component on the PCB board.
CHAPTER 4 Award BIOS Setup
Chapter 4 Award BIOS Setup 4.1 Introduction Award’s BIOS ROM has a built-in setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed memory (CMOS RAM) so that it retains the setup information when the power is turned off. 4.1.1 CMOS RAM Auto-backup and Restore The CMOS RAM is powered by an onboard button cell battery. When you finish BIOS setup, the data in CMOS RAM will be automatically backed up to Flash ROM.
Figure 4.1: Award BIOS Setup initial screen 4.3 Standard CMOS Setup Choose the “Standard CMOS Features” option from the “Initial Setup Screen” menu, and the screen below will be displayed.
