Field Description
Type Identifies the disk type. You can select one of these:
•
Auto (default) : Select this option when you want the
POST to query the hard disk for its parameters whenever
the POST runs. RadiSys recommends this option.
Note : If you set a hard disk to “Auto”, but no hard disk is
actually present, the BIOS queries the (non-existent) hard
disk until it times out, slightly increasing the duration of
the POST.
• None : Select this option if yours is not an IDE hard disk
drive.
• User : Select this option if you have an IDE disk but
cannot employ the “Autotype” feature. Then enter the
correct drive values for cylinders, heads, sectors/track, and
write precompensation.
• ATAPI Removable : Select this option if you have a
removable disk drive.
• IDE Removable : Provides support for high-capacity disks
that can be formatted as floppy or hard disks. This option
may be used for compact flash cards.
• CD-ROM : Select this option if you have a CD-ROM
drive.
• 1–39 : Select this option to specify a pre-determined
hard-disk drive type. These drive types, found in the
FDPT (Fixed Disk Parameter Table), are seldom used.
RadiSys recommends that you avoid using this option.
Note : For disks not supplied, consult the product
documentation.
