Some older drives may not support the auto-sensing feature. If
the drive parameters displayed on the screen do not match your
drive, you need to define your own drive parameters (see the
next section for instructions). You may also need to set the
remaining options on the screen, as described below.
The Multi-Sector Transfers option sets the number of sectors per
block that the hard disk uses in multiple sector transfers. The
more sector transfers per block, the faster your hard drive
performs. If this option is not automatically detected, you can
select 2,4,8, or 16 sectors.
The LBA Mode Control option enables or disables ISA logical
block address (LBA) mode control for each drive. If this option is
not detected automatically, and your drive supports LBA mode
control, select
Enabled.
Many drives larger than 528MB
support LBA mode control, but some older drives do not; check
the drive documentation.
The 32 Bit I/O option sets the I/O transfer rate for data read
from the disk. If your drive supports 32-bit I/O transfers, select
Enabled;
the default setting is
Disabled
(16-bit transfers).
The Transfer Mode option selects the method for transferring
data between the hard disk and system memory. If this option is
notautomatically
set, you can select Standard/Fast PIO 1
(thedefault),
Fast
PI0 2, Fast PI0 3,or Fast PI0 4.

own drive
parameters

parameters detected by the auto-sensing feature, you must
define your own drive parameters. Follow these steps:
1.
Move the cursor to Type and select User.
2.
Type the values in each field that are appropriate for your
hard disk drive.
3.
When you leave SETUP, make sure you save your changes.
