I waited for someone to ask exactly this question... :-)

As a matter of fact, yes, I have. Almost. It's for SunOS 3.5 on a 3/60.

The procedure on a Sun-2/120 should be pretty similar, but the mainbus 
address for the Emulex MD21 (SCSI/ESDI) controller is 0x80000 instead of 
0x140000. For a Xylogics (SMD) controller, it's 0xee40.

I haven't done this myself. Found the notes somewhere on the Net.


1.  Load Tape 1 into the tape drive.

2.  At the > prompt, enter:
         b st(0,0,0)
     The system will blink off and on once, and then print:
         Boot: st(0,0,0)
     Wait for th Boot: prompt.

3.  At the "Boot:" prompt, enter:
     This loads and starts the diag program.

4.  When you see the menu of disk controller, for a Sun 3/60, enter:
     This choice specifies the Emulex MD21 - SCSI/ESDI disk controller.
     You may need to choose a different controller for your

5.  At the prompt for mainbus address, enter:
     Again, this is for the Sun 3/60 with Emulex MD21.

6.  At the "which target?" prompt, enter:

7.  At the "which unit?" prompt, enter:

8.  When you see the menu of disk drives, choose the correct disk.

9.  Format the disk.
     a.  At the diag> prompt, enter:
         The program will then respond with SCSI format and the format>
     b.  At the format> prompt, enter:
         The program warns that this process destroys all disk data, and
         then asks "are you sure?"
     c.  Enter:
         Messages indicating correction of bad disk blocks may appear.
         These are normal and can be safely ignored.
         When formatting is complete, the system message "Done" and the
         format> prompt are displayed.
     d.  Exit the format program by entering:

10. To partition the disk, enter the following at the diag> prompt.

11. Select a partition table. You may also choose to modify it.

12. At the "OK to use this partition table?" prompt, enter:

13. When the system is ready, the diag> prompt will appear. Enter:
     The system asks:
         OK to use logical partition map?
         Are you sure you want to write?
     Enter "yes" to each question.

14. When you are finished labelling the disk, exit the diag program by
     The system returns a Boot: prompt.

15. Copy the mini-UNIX operating system from tape to disk.
     At each of the prompts listed below on the left, enter the
     associated response on the right:
         Boot:                            st(0,0,4)
         Size: 25220+4900+113452
         Standalone Copy
         From:                            st(0,0,5)
         To:                              sd(0,0,1)
     This process takes approximately 10 minutes to copy the mini-UNIX to
     the swap partition of the disk drive.  When the copy operation is
     finished, you will see the message "Copy completed", the number of
     bytes involved, and the Boot: prompt.

16. Boot mini-UNIX by entering:
         sd(0,0,1)vmunix -as

17. After a few lines of boot information, the booting program will stop
     and prompt for the root device. Enter:
     When booting is completed, you will see the # prompt.

18. Check the date by entering:
     If it is incorrect, set the correct date by entering:
         yy - year digits (note not Y2K compliant)
         mm - month digits
         dd - day digits
         hh - hour digits (24-hour clock)
         mm - minutes digits
         ss - seconds digits (optional)

19. Call the Setup program to load the UNIX operating system. At the #
     prompt, enter:
     The setup program contains five forms in which you enter information
     and select options.  I will not go into the details of the setup
     program since it is fairly straight forward.

20. After setup is completed, you should have SunOS 3.5 installed and
     running on your Sun3 system.


Hope this helps.
