4.2.10 Auto detect hard disk

The IDE HDD AUTO DETECTION utility can automatically detect
the IDE hard disk installed in your system. You can use it to self-
detect and/or correct the hard disk type configuration.

Figure 4-9: IDE HDD auto detection screen

4.2.11 Save & exit setup

If you select this option and press <Enter>, the values entered in the
setup utilities will be recorded in the chipset’s CMOS memory. The
microprocessor will check this every time you turn your system on
and compare this to what it finds as it checks the system. This record
is required for the system to operate.

4.2.12 Exit without saving

Selecting this option and pressing <Enter> lets you exit the Setup
program without recording any new values or changing old ones.
