To copy files  from the 3.5 to 5.25 the best way is to use the Minix
cpdir command; if some directories won't fit in their entirety on the
smaller format  disks you'll probably have to copy the leftover files
by hand.

It might be possible to copy the entire device file from one drive to
another to copy the boot disk, i.e., cp /dev/fd0 /dev/fd1.  I am not
sure this will work. I am pretty sure there is actually no more than 
360K of stuff on the 3.5" boot disk, so it should fit on the 5.25" disk. 

Possibly to make a 5.25" boot disk you'll have to go through building 
a new system image as described in the section on recompiling Minix.

There are some things that could help further down the road, but if you
are just getting started you don't have the resources. In particular
MXBoot and other systems for booting Minix from the hard drive provide
for putting the system image into a file on the Minix file system and 
using a modified boot procedure that knows how to read a file. This
makes it really easy to set up a new boot disk of any format, you just 
make a disk with the Minix file system, put the modified boot sector on
it, and copy the minix.image file to its root or /system directory.

Again, just running su without arguments, then typing the root password

These problems (specially Elvis crashing with exceptions), sound like the
binaries may be corrupted. Have you tried the original binaries from floppy?

For 1.5.10.1 you just need the boot disk. The patch tarfile contains, besides
Makedev and format, only source patches.

>for the 1.5.10.2 src.tar.Z patch archive? 

For 1.5.10.2 you can also just use the new boot disk, but to have full use of
the virtual consoles you'll have to edit a file on the root filesystem
(/etc/ttys, I think). You don't have to recompile, because the binaries
are included (actually just minix.img).

I guess I should write an amiga minix FAQ sheet, for now I'll

Oh, BTW, it helps to include the word 'amiga' in the subject line,

The Prentice Hall distribution of amiga minix has some bugs in, a.o.,
the floppy driver. Please try 1.5.10.1 or 1.5.10.2.

Not yet, the AmigaOS trackdisk.device uses the blitter to encode/decode
floppy tracks. So, there would be two ways to implement this
- Complicated (at least for me), using the blitter.
- Easier, using the CPU to encode/decode, but at least as slow as the current
  method.

>(3) Which hard drives are currently supported, including any

The PH distribution supports neither harddisks, nor 68010 and higher
processors.
The 1.5.10.1 (and higher) support processors up to the 68030 (68040 untested)
and Commodore harddisk controllers (A590, A2091, A3091 (builtin-A3000)).

Work is underway to implement memory protection/VM for the Atari ST/TT,
this code could easily be copied into the amiga version.

Dunno about the nice list, amiga-specific stuff is pretty rare (as far as I know
just the 1.5.10.1 and 1.5.10.2 updates). This stuff is available from
ftp.cs.vu.nl, directory /pub/sreiz/minix. For 68000 minix stuff
(mainly applications such as gcc), try plains.nodak.edu.

Size. Most GNU tools are large and most machines running Minix are
small. If you have a machine with a 68k processor or a 386 (and the
32-bit version of Minix) and at least 4MB RAM there should be little
problem.

Compiling GCC under Minix is probably a little difficult, since the
usual Minix C compilers (including bcc) lack floating point support. I
tried to cross-compile GCC 2.2.2 on a DECstation but had only limited
success (I can create .o files on the workstation which will link
correctly under Minix, but if I link them on the workstation, they will
not execute on Minix). You can get gcc 1.37.1 binaries for Minix/386
from various FTP sites.

> DItto for all the other GNU stuff.

Most other GNU programs work well.

PS: I have a 386 with 8MB. I can't say much about other configurations.

Is init different on 68k and PC-Minix? Init.c on PC-Minix 1.5 _does_
include <time.h> and the parameter is (time_t *)0, so there is no
problem.

Byte ordering has nothing to do with that. The upper 16 bits of the
return value are simply discarded, and the resulting value is sign
extended by the assignment to a long. Both PC-Minix and 68k-Minix
should deliver the same resultsvalue are simply discarded, and the resulting value is sign
extended by the assignment to a long. Both PC-Minix and 68k-Minix
should deliver the same results.

>Does it support MMU?

Unfortunately no.  The Prentice Hall version only supports the 60000 CPU, and
the 1.5.10.1 and 1.5.10.2 updates will only support the 020 and 030 CPU.  The
problem is that the 040 has different instructions for the cache control and
the MMU control, which are not compatible with the 030 instructions.  If
AmigaDOS recognized the 040 CPU (AmigaDOS 2.04 does), the minix loader
program attempts to turn off MMU translation using the 030 instruction which
is invalid on the 040.  The MOVEC CCR instruction used on the 030 to control
the cache will execute on the 040, but the 040 has new instructions that
actually control the cache.  The cache invalidate routines in mpx.s need to
be changed to recognize that the CPU is an 040 and execute the proper
instructions.

I think I was able to run Amiga Minix 1.5.10.1/1.5.10.2 on my PP&S 040 card
when I was still running AmigaDOS 1.3 and had the 040 copyback cache off
(which was required under 1.3 anyway).  AmigaDOS 1.3 recognized the CPU as
a 020 and the minix loader didn't attempt to turn off MMU translation.

Has anyone ever experienced after effects

I tried out the demo disk and since then (but not yet provably because of it)
my keyboard is not behaving the same. The symptom is that when I use
demacs in MSDOS, it makes it imposisble to use the numeric

I am investigating separately why DEMACS should have after effects, but
if it can, why can't minix?

I tried out the minix demo disk and at some point unmounted the floppy
that had all the commands in it. So I could not issue any commands.
So I rebooted with control-alt-delete. Then I tried to use PCPLUS to 
log into a mainframe and noticed that my keystrokes were not echoing
to the screen. I had to do a hard reboot by turning the machine off
and then it went away.

Later I tried to read a dvi file in MSDOS using dvivga and found that
it would not obey the arrow keys, the pagedn and pageup keys, etc.
In some cases, the machine hung when I tried to exit dvivga.

I don't know if this is related to having screwed up with minix or not.

I had this problem with the previewer before, when I installed ansi.sys
in order to be able to use demacs. It turned out that ansi.sys was
incompatible with dvivga. But then I found that I had a file named
tansi.sys (Trident ANSI.SYS) and if I used that instead, I could use
demacs as well as dvivga. So I don't understand why the problem  is
recurring.

Has anyone else ever had after effects like this? I would like to rule this
out as a source of the problem.

We are planning to speed up downloading of XINU to an LSI-11
using ethernet. We have MMU in our LSI-11. Does any body have
the code (both the LSI resident part and the download part)
or have any information on this ? If so please mail it to
me.

Thanks in advance.
