<Enter> to activate the following submenu screen for detailed options of these
items. Set the correct configurations accordingly. The items included in the
submenu are:
Type
Select the type of device connected to the system. The options are Not
Installed, Auto, CD/DVD and ARMD.
LBA/Large Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk
drive. In the LBA mode, the maximum drive capacity is 137 GB. For drive
capacities over 137 GB, your system must be equipped with a 48-bit LBA
mode addressing. If not, contact your manufacturer or install an ATA/133
IDE controller card that supports 48-bit LBA mode. The options are Disabled
and Auto.
Block (Multi-Sector Transfer)
Block Mode boosts the IDE drive performance by increasing the amount of
data transferred. Only 512 bytes of data can be transferred per interrupt if
Block Mode is not used. Block Mode allows transfers of up to 64 KB per
interrupt. Select Disabled to allow data to be transferred from and to the
device one sector at a time. Select Auto to allow data transfer from and to
the device occur multiple sectors at a time if the device supports it. The
options are Auto and Disabled.
PIO Mode
The IDE PIO (Programmable I/O) Mode programs timing cycles between the
IDE drive and the programmable IDE controller. As the PIO mode increases,
the cycle time decreases. The options are Auto, 0, 1, 2, 3, and 4.
Select Auto to allow the AMI BIOS to automatically detect the PIO mode.
Use this value if the IDE disk drive support cannot be determined.
Select 0 to allow the AMI BIOS to use PIO mode 0. It has a data transfer
rate of 3.3 MBs.
Select 1 to allow the AMI BIOS to use PIO mode 1. It has a data transfer
rate of 5.2 MBs.
Select 2 to allow the AMI BIOS to use PIO mode 2. It has a data transfer
rate of 8.3 MBs.
