PRODUCT NAME
NetBSD-Amiga 1.0, official release version from November 1994.
[MODERATOR'S NOTE: This is an update to Markus's previous
review of NetBSD, kernel version 635, found in our review
archives in the file software/unix/NetBSD. - Dan]
BRIEF DESCRIPTION
Freely distributable Unix-alike operating system for Amiga computers.
AUTHOR/COMPANY INFORMATION
Name: The Regents of the University of California, Berkeley
and many contributors.
Amiga port by Markus Wild of Zurich, Switzerland, with major
contributions from Bryan Ford and Mike 'mykes' Schwartz.
Merge with NetBSD-1.0 and major reworks applied by
Chris Hopps.
LIST PRICE
Freely distributable under the NetBSD disclaimer; see the COPYRIGHT
NOTICE section, below.
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
NetBSD 1.0 is a final release, so all information below is static.
New drivers and support for more peripherals is under development and is
probably implemented in a new release of NetBSD-current.
SYSTEM HARDWARE
An accelerated Amiga (68030, 68040) with a working MMU
(memory management unit). This includes most accelerator
boards (e.g., Commodore A2630), the Amiga 3000, and others.
A working FPU is required.
NetBSD does support the 68040 processor.
NetBSD is untested on 68020 environments.
The stock A500, A1000, A2000, A1200, and A4000/030 computers
have no MMU and so will not run NetBSD.
Requires at least 4 MB of contiguous Fast RAM.
8 MB or more of contiguous 32-bit RAM is recommended.
Requires at least 15 MB hard drive space for a minimal setup.
100 MB hard drive space needed for a full installation.
Actual use of NetBSD may require much more space; for
example, a serious developer may need 500 MB or more.
HARD DRIVE SUBSYSTEM
Amiga NetBSD supports the following hard-drive systems:
Amiga 3000 and 3000T internal SCSI host adapter.
A2091 SCSI host adapter for A2000.
GVP Series II SCSI host adapter for A2000 and A500.
PPI Zeus SCSI host adaptor for PPI 040 board
Magnum SCSI host adaptor
CSA SCSI host adaptor
Supra SCSI host adaptor
IVS SCSI host adaptor
IDE Adaptor of A4000 and A1200
(and some others)
Currently NOT supported:
Any PIO adapter such as Oktagon and ALF.
Almost every SCSI hard drive is known to work with Amiga
NetBSD. This includes the range of Quantum drives, Seagate,
Wren, DEC, Fujitsu and IBM.
SCSI tape drives (QIC, DAT) and SCSI CD-ROM drives (ISO and
Rockridge extension) are supported.
GRAPHICS
Standard Amiga ECS and AGA chip set.
Retina Graphics Board is supported.
(Experimental drivers exist for other boards - see below.)
SOFTWARE
The bootstrap loader works with almost any version of AmigaDOS.
COPY PROTECTION
None - as far as your Amiga is running with it.
MACHINE USED FOR TESTING
Amiga 3000 with 2 MB Chip RAM, 16 MB Fast RAM
Fujitsu M2623F (400MB), Apple CD300, 2 Conner CFP1060S, HP DAT
HP35470A
Picasso II graphics board
A2060 ArcNet board
A2065 Ethernet board
INTRODUCTION
["TTY-fighters attacking!" Con Solo shouted.]
For your own interest: I may use technical words which are very
common in Unix environments but meaningless to people who have never used
such a system. Amiga NetBSD may help you to enter the world of Unix, but
you will need third party help, such as Unix reference books and guidelines.
Amiga NetBSD-1.0 is the first freely distributable Unix for Amiga
systems, and enables the user to run a fully qualified Unix environment on
his own machine.
NetBSD takes over the Amiga, so it is not possible to run it
concurrently with AmigaDOS. So in this review, you will see references to
the "Amiga side" and the "NetBSD side" to indicate which operating system
(UNIX or AmigaDOS) must be running to accomplish a particular task. In
general, if a reference is missing, I am referring to the NetBSD side.
INSTALLATION
[Vitamin enriched for your reading pleasure!]
Amiga NetBSD is not intended to be installed by a novice in
terms of hard drive systems on Amiga. You definitely need to know how
to work with AmigaDOS HDToolBox.
But first, where to get Amiga NetBSD?
Before getting any of the archives, PLEASE get the FAQ (Frequently
Asked Questions) List, which should reside at the same places as NetBSD
itself. This list informs you how to install Amiga NetBSD, how much space is
needed, how to set up your hard drives, and much more.
If you have Internet access, you can ftp the needed archives from
ftp.uni-regensburg.de (the main site for Amiga NetBSD, there are
mirrors all over the world) from the directory:
/pub/NetBSD-Amiga/docs
The site is also reachable via WWW:
ftp://ftp.uni-regensburg.de
Also, some of the Aminet ftp sites mirror the NetBSD archive.
PLEASE DO CHECK your local mirror. NetBSD is *not* integrated in the AmiNet
archive, and hopefully never will - for several reasons. All official
NetBSD-1.0 mirrors should also distribute the Amiga binary distribution.
NetBSD is LARGE. You will need at least 10MB of "gzip-ed" archives to
have a standard NetBSD environment... and even more if you intend to work on
the kernel.
If you have no Internet access, then it is a LOT more difficult to
get Amiga NetBSD. Maybe you should ask someone to help you on Usenet
(comp.unix.amiga), either by sending you a tape or letting you copy it
directly from his/her hard drive. It's worth the effort.
NetBSD-Amiga 1.0 is made available on the "Meeting Pearls Volume II"
CD-ROM obtainable from your Amiga dealer.
NetBSD-1.0, the official release, contains a binary and source
distribution for the Amiga, as well as the official INSTALL text. So any
CD-ROM containing the official NetBSD-1.0 distribution should contain the
Amiga distribution as well.
You do not need a tape drive, but this is recommended, as it
eases the process of installing NetBSD. If you have either Ethernet
or PPP access, you probably will want to get only the basic kit at
first. This includes tools for Ethernet and PPP running TCP/IP; thus,
you can get the rest of NetBSD using a (local) network.
Also, the basic kit contains a Kermit transfer program, so it
is possible to get the required archives via modem or a null-modem
cable.
You need an 15MB partition for the root filesystem which is created
under NetBSD using a floppy disk as installation filesystem. This way the
installation is way easier than previous releases.
If you are careful, and if everything runs fine, you can start the
kernel using the supplied "loadbsd" tool.
You will hopefully see the Copyright information, and then some
numbers about your system memory. Then the kernel's built-in 'autoconfig'
logic detects the installed boards, such as graphics boards and SCSI host
adapters. Finally, the root filesystem should be detected and the system
boots into single-user mode.
You are running Unix on your Amiga now!
Now you need to play system administrator on your very own system.
You need to format the other disk partitions and copy the /usr tree from the
distributed archives.
Once you have done the initial installation, the rest is easy to do.
Get the ksrc archive if you intend to compile the kernel yourself. A
generic kernel and the sources for it are supplied, too.
REVIEW
The review is split into two parts: technical discussion and general
overview.
HISTORY OF AMIGA NETBSD (technical)
NetBSD-1.0 is based on the last public release of BSD 4.4-Lite (the
networking-2 release) by the University of Berkeley, as
