Large Hard Disk Modes
The last of the drive parameter entries – Mode – has four op-
tions, Normal, LBA, Large and Auto. The Mode settings are for
IDE hard disks only.
Normal
For IDE hard disks of 528MB or less.
LBA
This stands for Logical Block Addressing, the current standard
access mode for large IDE hard disk drives. It allows the use of
hard disks larger than 528MB by causing the IDE controller to
translate between the logical address it creates and the hard
disk's actual physical address. The maximum drive size sup-
ported is 8.4GB.
Large
For 1GB or smaller drives with more than 1024 cylinders and
no LBA support. This access mode causes the Operating Sys-
tem to treat the drive as if it has fewer than 1024 cylinders by
dividing the cylinder total in half and doubling the number of
heads. Drives needing this mode are less common.
Most large IDE hard disk drives currently available use the
LBA mode. Use the AUTO setting to automatically detect the
correct mode for new drives.
Floppy Disk Drives
The two floppy disk drive items set the drive type for drives A
and B, and must be entered manually. The options are
360KB, 5.25 in.
1.2MB, 5.25 in.
720KB, 3.5 in.
1.44MB, 3.5 in.
2.88MB, 3.5 in.
