the operating system.
The table below shows the maximum hard drive partition size and total capacity supported by
different operating systems:
Operating System
MS DOS
Win95 OSR1
Win95 OSR2
LARGE mode: This is an extended HDD access mode supported by Award Software. Some IDE
HDDs contain more than 1024 cylinders without LBA support (in some cases, user does not
want LBA). The Award BIOS provides another alternative to support these kinds of LARGE
mode:
CYLS HEADS
1120 16
560 32
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 13h 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 software
are 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 system do not support either LBA or LARGE and must utilize the
Standard mode. UNIX can support drives larger than 528MB.
