GmING STARTED
When PASCAL boots up, it determines what mass storage devices are
connected to the computer, and makes them accessible to the file
system. When a disk is found, it is assigned with a unit number. Some
of the nominal assignment of unit number are as follows:
Ber i ng Model
Winc. unit'
f1
oppy uni t ,
------------
------------
-------------
30xx
11 to 40
N/A
33xx
11 to 40
3
35xx
11 to 40
3
38xx
11 to 40

Under auto-configuration, it assumes at most one hard disk will be
present, so it stops configuring the other hard disks once the first one
is located. For disk subsystem with multiple volumes of 4.8 MB, 9.7 MB,
or 14.5 MB, which emulates multiple units of HP equivalent disks, only
volume 0 will be recognized by auto-configuration. Under those cases,
CTABlE need to be changed to configure all units. Consult Appendix E
for instructions.
Once a hard disk is found, it is automatically partitioned into
several volumes which are assigned consecutive unit numbers beginning
with '11. The size of each volume and the number of volumes depend on
the type of disk.
NOTE: All units need to have a directory with a legal volume label,
so that it can be listed by the VOLUME command. Thus, it is important
to have the disk initialized before it can be used.
How to Boot and Initialize
The following example demonstrates how to boot from an external
floppy drive and initialize a Winchester volume. It assumes you have
Model 33xx, or 35xx, or 38xx, and Boot ROM 3.0. By changing the logical
unit(lu) number, the same procedure could apply to the initialization
of other Winchester and floppy media.
1. Turn off your computer.
2. Insert the diskette labeled IBOOT" into the floppy drive.
3. Turn on the computer.
4. When instructed to insert the diskette labeled IISYSVOL: ", do so
and press the "X" key to continue.
