computer. Before downloading any of your existing software onto the drive, complete
the following steps first:
1. Protect Your Data! Before doing anything else, make a complete backup
of all the software on your bootable drive. Before you load any new
software onto the bootable drive, make sure all the data is copied
onto some form of backup media. Make sure you are able to read the
data on your backup media; be absolutely sure the data on your backup
media is restorable.
2. Create A Warm Boot Tape! A warm boot tape allows you to access the
computer in situations where you are not able to boot from the hard disk
drive. If you have a warm boot tape, you will be able to access your hard
disk drive and correct the situation which prevented you from booting.
Without a warm boot tape, it will be much more difficult to access the
computer and correct the problem. See the
Systems Commands
Reference Manual
for information on how to create a warm boot monitor
and a bootable tape.
Be careful when copying your existing software over to your new bootable drive. When
transferring software to the DSK0: device, make sure you use the /NOD (no delete)
switch with your copy command; this will prevent you from over-writing the software
included on your new bootable drive.
