abled, that is, if the device was not previuosly formatted with the LBA mode
disabled.

Block (Multi-Sector Transfer)
Auto
Data transfer from and to the device occurs multiple sectors at a time.
Disabled

PIO Mode
Selects the data transfer mode. PIO means Programmed Input/Output.
Rather than have the BIOS issue a series of commands to effect a transfer
to or from the disk drive, PIO allows the BIOS to tell the controller what it
wants and then let the controller and the CPU perform the complete task by
themselves. Your system supports ve modes, 0 to 4, which primarily differ
in timing. When Auto (default) is selected, the BIOS will select the best avail-
able mode after checking your drive.
Auto
The BIOS will automatically set the system according to your hard disk
drive’s timing.
Mode 0-4
You can select a mode that matches your hard disk drive’s timing. Caution:
Do not use the wrong setting or you will have drive errors.
DMA Mode
This eld allows you to select the Ultra DMA in use. When Auto is selected,
the BIOS will use the best available option after checking your hard drive or
CD-ROM.
Auto
Automatically detects the DMA mode.
