BIOS Description
A new HDD accessing method to overcome the 528 Megabyte
bottleneck.
The number of cylinders, heads and sectors shown in setup may not
be the number physically contained in the HDD.
During HDD accessing, the IDE controller will transform the logical
address described by the sector, head and cylinder number into
its own physical address inside the HDD. The maximum HDD size
supported by LBA mode is 8.4 Gigabytes.
LARGE mode
Some IDE HDDs contains 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 that the number of cylinders is less than
1024 by dividing it by 2. At the same time, the number of heads is
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 the IDE hard
disk mode and set as one of the three HDD modes.
3. Remark
To support LBA or LARGE mode regarding HDDs, there must be
softwares 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.
Power - On Boot
If you have made all the changes to 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 " R E SET" button on the system
case. You may also restart the system by simultaneously pressing
the< Ctrl >, < Alt > and < Del > keys.
