Transfer Mode
This field specifies the transfer mode for the IDE hard disk drive.
Standard

2 Sectors

4 Sectors
,
6 Sectors
,
8 Sectors
,
16 Sectors
The set number of blocks (sectors) is transferred for each interrupt.
LBA Translation
This field enables and disables the LBA (Logical Block Addressing) mode. LBA
mode allows you to install and use hard disks with a capacity of more than 528
Mbytes. If a hard disk supports LBA mode, you can use the full capacity of the
IDE hard disk.
The default entry depends on the installed IDE hard disk drive. Change the default
entries only if you are installing another hard disk drive.
!
You may only use IDE drives in the LBA mode selected when they were
set up. In other words, if you set up a hard disk with LBA mode
disabled
,
you may only operate the hard disk with LBA mode
disabled
.
Enabled
If the hard disk supports LBA and it has a capacity of more than
528 Mbytes, the BIOS translates the hard disk parameters,
allowing the disk's full capacity to be used.
If the hard disk does not support LBA, its parameters are not
translated.
Disabled
The BIOS uses the hard disk parameters and supports a maximum
capacity of 528 Mbytes.
PIO Mode
The PIO (Programmed Input Output) Mode defines the transfer rate of the IDE
hard disk drive.
Standard
0,8 Mbyte/s to 2 Mbytes/s (default entry)
Fast PIO 1
2 Mbytes/s to 4 Mbytes/s
Fast PIO 2
4 Mbytes/s to 5 Mbytes/s
Fast PIO 3
5 Mbytes/s to 10 Mbytes/s
Fast PIO 4
10 Mbyte/s to 16 Mbyte/s
