Starting Setup
The BIOS is immediately activated when you turn on the
computer. The BIOS reads system configuration in CMOS
RAM and begins the process of checking the system and
configuring it through the Power-On-Self-Test (POST).
When the preliminary tests are complete, the BIOS searches
for an operating system on one of the system’s data storage
devices (hard drive, CD-ROM, etc). If an operating system is
found, the BIOS will launch that operating system and hand
over control to it. You can enter the BIOS setup by pressing
the [Delete] key when the machine boots up and begins to
show the memory count.
