↑ ↓ ↵ move between items

← → select values

Use the up and down cursor keys (↑ ↓) to move between items. Use the left and right

cursor keys (

← → ) to scroll through the available choices for each item.

Disk type AT denotes the many types of non-SCSI PC/AT compatible drives

including IDE. You can scroll through a set of numbered types; the physical

configuration is displayed for each. Scroll through the numeric drive types to find the

one matching the characteristics of the hard drive installed.

Choose disk type EXM Flash if you are using an EXM flash disk. An EXM flash

disk can be made the boot device by making EXM Flash the drive C: type. However,

if Drive C: is EXM Flash, Drive D: must

be set to None.

Choose None if there is no hard disk present. This avoids the timeout period used by

the BIOS to conclude that there is no responding device.

User-Definable Drive Types

If the correct AT disk type is not listed, the EPC provides user-editable drive types 48

and 49. Select either of these drive types. Use the TAB key (

→| )or the left and right

cursor keys (

← →) to move to the next (or previous) field. Note that the default

settings for MBytes, Cylinders, Heads, and Sectors is 1. MBytes is a display-only

field calculated by the BIOS. Move the cursor to each field (Cyls, Heads, and

Sectors) and type the value for that field.

The BIOS allows use of the following maximum values:

Cylinders 1023 Heads 63 Sectors 16
