BIOS KP6-LA
Page 4-26
BIOS tricks DOS (or other OS) 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
INT 12h in order to access the right HDD address!
Maximum HDD size:
no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x bytes per sector ( 512)
1 GigaByte
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 a 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.
4-10 HDD Low Level Format
Interleave: Select the interleave number of the hard disk drive you wish to perform
a low level format on. You may select from 1 to 8. Check the documentation that
came with the drive for the correct interleave number, or select 0 for automatic
detection.
Auto scan bad track: This allows the utility to scan first then format by each track.
Start: Press<Y>to start low level format.
3-11 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.
