- This directory contains a copy of Ultrix-11 3.0 from Ken Wellsch. He says:
-
- This is purely a binary distribution. I used to run it on my 11/44
- system. I forget the vintage of this tape, but I'm thinking circa
- 1985. The tape is the usual boot tape image -- in this case matched
- up with the block size record info so that it can be reproduced to
- match the same original blocking factors. The tape tools I used to
- do this, as sloppy as they are, are also present. -- Ken
-
- I haven't had a chance to look at this, however, here's what I can see:
-
- tapedump.gz is the gzipped Ultrix-11 tape
-
- tapelog show the number of blocks, their sizes, and the EOFs,
- so it should be possible to restore the tape from the tapedump.
-
- tapecontents also indicates the sizes of all the tape records,
- and also describes what they are
-
- file33-toc, file34-toc and tarcontents (I think) describe
- the files in Ultrix-11.
-
- I have no idea what hardware Ultrix-11 will run on or support. If anybody
- can help me here, I'd appreciate it very much. However, a strings on the
- tape image reveals the following install information:
-
-
- ****** ULTRIX-11 System Disk Load Program ******
-
- This program loads the base ULTRIX-11 system from the distribution
- media onto the system disk, then bootstraps the system disk. After
- booting, the setup program begins the initial setup dialogue.
- Before loading can begin, you need to answer some questions about
- your system's configuration. Enter your answer, using only lowercase
- characters, then press <RETURN>. If you need help answering any of
- the questions, enter a ? then press <RETURN>.
- To correct typing mistakes press the <DELETE> key to erase a single
- character or <CTRL/U> to erase the entire line.
-
- ****** WARNING ******
- Installing the ULTRIX-11 software will overwrite your system disk.
- In addition, the ULTRIX-11 V3.0 file system is not compatible with
- the file systems used by previous ULTRIX-11 releases or any other
- software systems. Existing user disks must be converted to the new
- 1K block file system.
- DO NOT PROCEED UNTIL YOU HAVE READ INSTALLATION GUIDE SECTION 1.7
- Proceed with the installation <y or n> ?
- The target processor is the CPU on which the ULTRIX-11 software
- will actually be used, this may or may not be the current CPU.
- If you are installing from a magtape distribution and your CPU
- does not have a magtape unit, you can install the software on a
- processor with a magtape drive, then move the software to the
- target processor.
- Please enter one of the following supported processor types:
- 23, 24, 34, 40, 44, 45, 53, 55, 60, 70, 73, 83, 84
- The Micro/PDP-11 will be one of the following processor types:
- 23 KDF11-B
- 53 KDJ11-D
- 73 KDJ11-A
- 83 KDJ11-B
-
- ****** CAUTION ******
- You must surface verify RP04/5/6 disks, type ?<RETURN> for help!
- Disk surface verification involves a write/read/compare test of
- each block on the system disk, using a number of test patterns.
- Any disk block which fails this test will be entered into the bad
- block file and automatically replaced by an alternate disk block.
- DIGITAL recommends that you surface verify your disk, unless you
- are certain that the data integrity of your disk media is accept-
- able and that it contains a valid bad block file.
- For RP04/5/6 disks, you must surface verify the disk unless you
- are absolutely sure the pack has been initialized with DSKINIT.
- Even if the disk pack already has a valid bad block file, bad
- block replacement will not function properly until the disk has
- been initialized by the DSKINIT program.
- The disk surface may be verified using up to eight different
- test data patterns. The thoroughness of the surface verification
- increases with the number of test patterns that you run. However,
- using a large number of test patterns can be very time consuming
- because, each pattern writes and reads every block on the disk.
- The following table gives the approximate run time per pattern:
- Selecting <1> test pattern will cause the `worst case' data
- pattern to be used for disk surface verification.
- Formatting the disk involves organizing the data bits on each
- disk track into 512 byte sectors and writing the appropriate
- format information in the header words of each sector header.
- DIGITAL recommends that you format the disk, unless you are
- certain that it is properly formatted.
- The attempted operation failed to complete successfully. The
- procedure is to determine the cause of the failure, then retry
- the operation. Some possible causes of such failures are:
- o The system disk is write protected.
- o The system disk is off-line,
- o The system disk media may be defective.
- o There may be a fault in the system hardware.
- Answer `yes' if you wish to retry the operation.
- Answer `no' to abort the entire installation.
-
- ****** CAUTION ******
- You must scan MSCP disks for bad blocks, type ?<RETURN> for help!
- The bad block scan program qualifies disk media for use with the
- ULTRIX-11 software by reading the disk and printing information
- about any bad blocks encountered during the read.
- For MSCP disks (RD51 RD52 RD53 RC25 RA60 RA80 RA81) the bad block
- scan program automatically replaces each bad block by revectoring
- it to a replacement block. For all other disks, the bad block scan
- program only identifies bad blocks.
- When the bad block scan has been completed, the program will warn
- you if the disk cannot be used with the ULTRIX-11 software.
- DIGITAL recommends you answer `yes', unless you are certain your
- disk meets the UTLRIX-11 media requirements.
- FATAL ERROR: while attempting to return to Boot:
- Execute the hardware bootstrap for your distribution load device,
- that is, RX50, magtape, etc., to return to the Boot: prompt.
- A typical ULTRIX-11 system disk layout is:
- +-------------+------------+
- | SYSTEM AREA | USER FILES |
- +-------------+------------+
- The system area consists of: ROOT, SWAP & ERROR LOG, and /USR.
- The remainder of the disk may be allocated for user file storage.
- DIGITAL recommends you scan the entire surface of your disks for
- bad blocks. However, you may choose to scan only the system area.
- This option can be used to expedite the installation if you are
- recovering from an error and/or you have already scanned the disks
- for bad blocks.
