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 the data to be transferred from and to the device one sec-
tor at a time. Select "Auto" to allows the data transfer from and to the device
occur multiple sectors at a time if the device supports it. The options are Auto
and Disabled.
