Chapter 2 System Utilities Most systems are already configured by the manufacturer or the dealer. There is no need to run Setup when starting the computer unless you get a Run Setup message. The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM.
Entering Setup Power on the computer and the system will start POST (Power On Self Test) process. When the message of “Press DEL to enter SETUP” appears on the screen, press NOTE: If the message disappears before you respond and you still wish to enter Setup, restart the system by turning it OFF and On.

Power-On Self-Test (POST) Each time you turn on the system, the Power-on Self Test (POST) is initiated. Several items are tested during POST, but is for the most part transparent to the user. The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the system components, and controls the operation of the power-on password option.
When POST executes a task, it uses a series of preset numbers called check point to be latched at port 80h, indicating the stages it is currently running. This latch can be read and shown on a debug board. The following table describes the Acer common tasks carried out by POST. A unique check point number represents each task.
Checkpoint Description Auto detect flash type to load appropriate flash R/W codes into the run time area in F000 for ESCD & DMI support. Reserved Use walking 1’s algorithm to check out interface in CMOS cir- cuitry. Also set real-time clock power status, and then check for override.
