LBA/Large Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk drive. In LBA mode,
the AMC module supports drive capacities greater than 137 GB (48-bit LBA mode).
Optimal and Fail-Safe default settings: Auto
Block (Multi-Sector Transfer)
Optimal and Fail-Safe default settings: Auto
PIO Mode
IDE PIO (Programmable I/O) mode programs timing cycles between the IDE drive and the pro-
grammable IDE controller. As the PIO mode increases, the cycle time decreases.
Optimal and Fail-Safe default settings: Auto
SETTING DESCRIPTION
Disabled Use this setting to prevent the BIOS from using Large Block Addressing mode control on the
specified channel.
Auto Use this setting to permit the BIOS to auto detect the Large Block Addressing mode control
on the specified channel.
SETTING DESCRIPTION
Disabled Use this setting to prevent the BIOS from using Multi-Sector Transfer on the specified chan-
nel.
The data transfer to and from the device will be one sector at a time.
Auto Use this setting to permit the BIOS to auto detect device support for Multi-Sector Transfers
on the specified channel.
If supported, the data transfer to and from the device will be multiple sectors at a time.
SETTING DESCRIPTION
Auto Use this setting to permit the BIOS to auto detect the PIO mode.
Specify Auto if the IDE disk drive support cannot be determined.
0 Use this setting to permit the BIOS to use PIO mode 0.
This mode has a data transfer rate of 3.3 Mbit/s.
1 Use this setting to permit the BIOS to use PIO mode 1.
This mode has a data transfer rate of 5.2 Mbit/s.
2 Use this setting to permit the BIOS to use PIO mode 2.
This mode has a data transfer rate of 8.3 Mbit/s.
3 Use this setting to permit the BIOS to use PIO mode 3.
This mode has a data transfer rate of 11.1 Mbit/s.
4 Use this setting to permit the BIOS to use PIO mode 4.
This mode has a data transfer rate of 16.6 Mbit/s. This setting generally works with all hard
disk drives manufactured after 1999. For other disk drives, such as IDE CD-ROM drives,
check the specifications of the drive.
