for the custom boot list.
The default boot sequence is:
Note:
1. The primary diskette drive.
2. The CD-ROM drive.
3. Tape drive.
4. Hard disk drive.
5. Network device.
To change the custom boot list, enter a new order in the New
column, then click on the Save icon. The list of boot devices is
updated to reflect the new order.
Attention:
To change the custom boot list back to the default values, click
on Default. If you change your startup sequence, you must be
extremely careful when performing write operations (for
example, copying, saving, or formatting). You can accidentally
overwrite data or programs if you select the wrong drive.
