LBA/Large Mode
The LBA (Logical Block Addressing)/Large Mode option allows you to enable or disable support for IDE devices with
capacities greater than 528MB. The maximum drive capacity in the LBA mode is 137GB.
Auto
This setting allows the BIOS to auto-detect LBA mode control on the specified channel (if the device
supports it and the device is not already formatted with LBA Mode disabled).
Disabled
Disables the LBA Mode and prevent the BIOS from using LBA mode control on the specified channel.
11.3.2.9.
Block (Multi-Sector Transfer)
If your hard disk supports the block mode, select Auto for the automatic determination of the number of the blocks per
request. Several sectors can be at the same time read/written. The data transfer rate will be increased.
Available settings are:
Auto
and Disabled.
Auto
The data transfer from and to the device occurs multiple sectors at a time if the device supports it. Block
mode allows transfers of up to 64Kb per interrupt.
Disabled
The data transfer from and to the device occurs one sector at a time. Only 512 byte of data can be
transferred per interrupt if block mode is not used.
This setting should be used only if read and write failures occur with “Auto”.
