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.
