Saving settings
Changes made in the BIOS Setup Utility must be saved so they can take affect on
the next system boot. Exceptions are the time and date, which are updated and
saved immediately. To save changes, select Save & Exit Setup on the main menu,
or press F10 at any time. To exit Setup without saving changes, select Exit
Without Saving or press Esc on the main menu.
You can save your settings to a file using the CMOS Save Utility and then copy
them to other units using the CMOS Restore Utility. These utilities can be
downloaded from the IBM Retail Store Solutions Web site at www.ibm.com/
solutions/retail/store
Boot device order
The boot device order is a setting that you can configure. This function controls the
devices from which the system can be booted and the order in which they are
started. This function is located on the Advanced BIOS Features menu as First
Boot Device , Second Boot Device , and Third Boot Device . Navigate to each
item and press Enter to see a list of available boot devices.
The system default is:
v First Boot Device = USB-HDD
v
Second Boot Device = HDD-0
v Third Boot Device = LAN
With this setting, the system attempts to boot first from a diskette in a USB diskette
drive, then from hard disk drive 0, then from the LAN. If no items are bootable, the
system will repeatedly try the boot list in order until successful.
Restoring CMOS default settings
To clear your CMOS settings and restore the default settings, follow these steps:
Note: Be sure to record your customized settings to reset them later.
1. Power off the system unit and disconnect the AC power cord.
2. Follow the instructions in “Removing the covers” on page 29 to remove the
covers and in “Removing the top plate” on page 32 to remove the top plate.
