Power-On Boot - QDI P5I430TX Titanium IB+ Manual

AWARD BIOS Description
During HDD accessing, the IDE controller will transform the logical address
described by sector, head and cylinder number into its own physical
address inside the HDD. The maximum HDD size supported by LBA mode is
8.4 Gegabits.
LARGE mode
Some IDE HDDs contain more than 1024 cylinder without LBA support (in
some cases, users do not want LBA). The Award BIOS provides another
alternative to support these kinds of HDD.
BIOS tricks DOS (or other OS) so the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads are multiplied by 2. A
reverse transformation process will be made inside INT13h in order to access the
right HDD address.
Auto detect
If using Auto detect, the BIOS will automatically detect IDE hard disk mode
and set it as one kind of HDD modes.
3.11.3 Remark
To support LBA or LARGE mode of HDDs, there must be some software
involved which are located in Award HDD Service Routine(INT13h). 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.
3.12 Power - On Boot
If you have made all the changes to the CMOS values and the system can not boot
with the CMOS values selected in Setup, restart the system by turning it OFF then
ON or press the "RESET" button on the system case. You may also restart the
system by simultaneously pressing the < Ctrl >, < Alt > and < Del > keys.
