12.0AM-137 BOARD FIRST TIME BOOTUP
With your new AM-137 board installed, it’s time to power up your computer. Plug a
terminal cable into port #0 on your computer’s rear panel. Turn the computer’s power
switch to the on position.
As your computer boots for the first time, you will see a number of errors as the system
initialization command file is processed. The errors appear because only the first
TRMDEF statement has the correct AM318 TRMDEF statement. All other TRMDEF
statements will generate errors, because they contain the incorrect driver name. Ignore
these errors and allow your computer to complete the boot process.
If you have a DAT or Tandberg magnetic tape drive, it will not be functional until you
define the SCSI dispatcher in your AMOS32.INI file. Instructions for enabling the SCSI
dispatcher are included in this section.
After the computer has completed the boot process, create a TEST.INI file using the
following commands:
LOG SYS:
RETURN
COPY TEST.INI=AMOS32.INI
RETURN
Use AlphaVUE to edit the TEST.INI file and make the following changes:
1.The AM-137 board has a much higher queue block requirement than your old
CPU board. Find the QUEUE block statement in the TEST.INI file and set it to
1000. For example, change:
QUEUE 250
to
QUEUE 1000
2.Next, you need to define the SCSI dispatcher. The SCSI dispatcher is a
communication module that controls the AM-137 board’s high-performance SCSI
interface. The dispatcher also makes it possible for the SCSI controller to
communicate with SCSI devices other than disk drives (i.e., magnetic tape and
CD-ROM drives).
In order to install the dispatcher, the command:
SCZDSP SCZRR
must be entered in the system initialization command file after the JOBALC
statements, but before the first DEVTBL command.
