If the root directory controller number is changed in the Preferences menu,
the "sash" variable is not adjusted to the new value. To pick up the change,
you have quit from the "sash" and rerun it.
Normally, when "sash" is first invoked, it performs a "chroot" command to
whatever "sash" variable "ROOT" was set to in a previous session. If the
root directory controller number in the menu is changed, the "sash" variable
"ROOT" changes to that number -- but it is not "export"ed.
To launch A/UX from a different drive, choose either of the following methods:
- Issue the "launch (x, y, z)/unix" command.
- or -
1) Issue the "chroot (x, y, z)" command (where x is the SCSI ID, y is SCSI
subdrive ID, and z is the slice number in the drive).
2) Then issue the "launch" command. (Selecting a different controller number
from the menu or setting the variable "ROOT" immediately does not affect
the change on the root directory.)
