This just ensures that "Boot is run, it doesn't say where rom.

These are temporary, and only works for your current session, so won't
persist beyond a power down, or reset.

Assuming that it did boot from the drive in IDEFS this is probably
redundant as it will already be set to this.

This configures the computer to look for !Boot on the IDEFS file system.
This setting is retained over a reset or power down.

One is temporary, one is 'permanant'. If you needed to change the OPT
settings for the drive, you would need to specify the IDEFS drive by
selecting IDEFS and the drive number, but generally this is set when you
format the drive and never changed. You can see what it's currently set
to by typing
*IDEFS
*.

at the command line.

Hope this helps, if not then probably easiest to discuss it at the SROUG
meeting next week.
