LOADING UNIX SVR4 03.02.00 ONTO AN NCR 3416

1.       Reason:

Loading SVR4 03.2.0 onto an NCR-3416 system, with a Buslogic - PXA (SE) installed.

Ignore this Info release if the embedded adapter AIC-7770 SCSI controller is used.

Some NCR 3416 will have the embedded SCSI, controlling the root drive and tape devices and the Buslogic - PXA (SE) controlling the data drives.

In this instance, DO NOT change any embedded configuration, but it maybe necessary to select a different IRQ for the Buslogic - PXA (SE).

During testing of SVR4 03.2.0 on NCR platforms, problems have been experienced loading onto NCR-3416.

2.       Symptoms:

NCR-3416 with Buslogic - PXA (SE) SCSI boards installed, do not scan the SCSI removable (tape) devices for bootable Unix media. The system loads the Unix loaders from the flexible drive then the console display clears with the cursor top left and system is now hung.

3.       Resolution:

Boot from system configuration utility (SCU)

<CR> at the NCR LOGO screen

<CR> at Welcome screen

select 'configure computer' at main menu.

Please wait……..

= select step 3 'view or edit details' from Configuration Menu.

Using cursor arrow keys move down to 'Installed Adapters' i.e. Digiboard, Network, Buslogic SCSI.

NOTE: Make a note of adapter settings before changes are made.

Change the interrupt address (IRQ) of the network card (if installed) to 15.

Change the interrupt address (IRQ) of the Buslogic - PXA (SE) to INT 10 level

The settings for digiboard do not need to be changed.

When complete, press <F10> Done

From the configuration menu select Step 5 'save and exit'

<CR> Save the configuration and restart the computer

At reboot screen <CR>

Remove SCU diskette

Commence installation of SVR4 03.2
