DEC Format floppy (for formatting disk prior to 4.2BSD install) - TUHS

21 Jan 2022

Hi all,

Has anybody ever seen a console floppy image anywhere on the internet 
labeled:

/"RX11 VAX DSK LD DEV #1"/

It is referenced in BSD 4 documentation with respect to formatting disks 
(edited):

    USING DEC SOFTWARE TO FORMAT
    Warning: These instructions are for people with 11/780 CPU’s.

    You should shut down UNIX and halt the machine to do any disk
    formatting.

    Formatting an RP06. Load the console floppy labeled, "RX11 VAX DSK
    LD DEV #1" in the console disk drive, and type the following commands:
...
 >>BOOT     DIAGNOSTIC SUPERVISOR.
ZZ-ESSAA-X5.0-119 23-JAN-1980 12:44:40.03
    DS>ATTACH RH780 SBI RHO 8 5
    DS>ATTACH RPO6 RHO DBA0
    DS>SELECT DBAO
    DS>LOAD EVRAC
    DS>START/SEC:PACKINIT

    This is for drive 0 on mbaO; use 9 instead of 8 for mbal, etc.
