   Note:

To support LBA or LARGE mode of HDDs, there must be some
software involved. All the software is located in the Award HDD
Service Routine (INT 13h). It may fail to access a HDD with LBA
(LARGE) mode selected if you are running under an Operating
System which replaces the whole INT 13h.

UNIX operating systems do not support either LBA or LARGE and must utilize
the Standard mode. UNIX can support drives larger than 528MB.

4-11 Save & Exit Setup

The “SAVE & EXIT SETUP” option will bring you back to the boot up procedure
with all the changes you just recorded in the CMOS RAM.

4-12 Exit Without Saving

The “EXIT WITHOUT SAVING” option will bring you back to normal boot up
procedure without saving any data into CMOS RAM.

All old data in the CMOS will not be destroyed.
