IDE Interface Configuration

Use Setup to specify your IDE hard disk drive types. Refer to the Setup section beginning on page
2–62 for details.

If you do not find a drive type whose displayed parameters match the drive you are using, use drive
type USER. It allows you to manually enter the drive’s parameters. The drive manufacturer
provides the drive parameters—check the drive’s documentation for the proper values to enter.

If you are using a newer IDE drive, use drive type AUTO. It automatically configures the drive type
parameters from information provided by the drive itself.

Compact Flash Solid-State Disk

The Little Board/P5x connector J23 supports a Compact Flash device, a solid-state IDE hard-disk
emulator. It acts as a removable hard-disk drive. You can format, read, and write the Compact
Flash device much as you would a standard IDE drive.
