-
-Once you see the `SYSTEM FAILURE` message, this is actually an
-invisible prompt. To access firmware mode, type the default 3B2
-firmware password `mcp`, then press Enter or carriage return.
-
-You should then be prompted with:
-
-    Enter name of program to execute [  ]:
-
-Here, you may type a question mark (?) and press Enter to see a list
-of available firmware programs.

-Booting UNIX SVR3 on the 3B2/400
---------------------------------
-
-UNIX System V UNIX is the only operating system available for the 3B2.
-To boot UNIX, attach the first disk image from the 3B2 "Essential
-Utilities" distribution.
-
-    sim> ATTACH IFLOPPY <floppy-image>
-    sim> BOOT
-
-Once you reach the `SYSTEM FAILURE` message, type `mcp` to enter
-firmware mode. When prompted for the name of a program to boot, enter
-`unix`, and confirm the boot device is `FD5` by pressing Enter or
-carriage return.
-
-    Enter name of program to execute [  ]: unix
-            Possible load devices are:
-
-    Option Number    Slot     Name

-Installing SVR3 on the 3B2/400
-------------------------------
-
-To install SVR3 to the first hard disk, first, attach a new image
-to the IDISK0 device:
-
-    sim> ATTACH IDISK0 <hd-image>
-
-Then, boot the file `idtools` from the "3B2 Maintenance Utilities -
-Issue 4.0" floppy diskette.
-
-From `idtools`, select the `formhard` option and low-level format
-integrated disk 0. Parameters for the default 72MB hard disk are:
-
-                   Drive Id: 5
-           Number cylinders: 925
-          Number tracks/cyl: 9
-       Number sectors/track: 18
-        Number bytes/sector: 512
-
-After low-level formatting integrated disk 0, boot the file `unix`
-from the first diskette of the 3B2 "Essential Utilities" distribution,
-and follow the prompts.
