Setting the Boot Drive Sequence
The Boot Drive Sequence section lists boot priorities (1st, 2nd, 3rd and 4rd ) for bootable drives in your 
computer.
For example, the default value (1st:  Floppy Disk, 2nd:  CD-ROM, 3rd:  Hard Disk) tells the computer to first 
search for a bootable floppy disk in the floppy drive.  If it finds one present, it boots up from that floppy disk.  If 
not, the computer continues to search for a bootable CD-ROM in the CD-ROM drive.  If it cannot boot up from 
the CD-ROM drive, it continues by booting up from the hard disk.  
To set the boot drive sequence, use the 
w
