Revision as of 20:46, 18 November 2010

Installation of NetBSD 1.2 on the MicroVAX II is a little shaky... Also I found that the miniroot from 1.3 is far more stable, and doesn't page on itself...!!

To keep things simple I'm going to stick with the examples...

sub end_file {
  print "\x00\x00\x00\x00";
}

sub add_file {
  my($filename, $blocksize) = @_;
  my($block, $bytes_read, $length);

  open(FILE, $filename) || die("Can't open $filename: $!");
  while($bytes_read = read(FILE, $block, $blocksize)) {
    if($bytes_read < $blocksize) {
      $block .= "\x00" x ($blocksize - $bytes_read);
      $bytes_read = $blocksize;
    }
    $length = pack("V", $bytes_read);
    print $length, $block, $length;
  }
  close(FILE);
}

Preparing the hard disk

the instructions need us to know the geometry of a disk, and all of it's parameters.. So for me it's a tad daunting, but they do give an RD54 as an example. Here is the disktab entry: 

rd54|RD54|DEC RD54 on Microvax:\
        :ty=winchester:ns#17:nt#15:nc#1225:\
        :dt=MSCP:\
        :pa#15884:oa#0:ba#8192:fa#1024:\
        :pb#33440:ob#15884:bb#8192:fb#1024:tb=swap:\
        :pc#311200:oc#0:bc#8192:fc#1024:\
        :pd#15884:od#49324:bd#4096:fd#512:\
        :pe#55936:oe#65208:be#8192:fe#1024:\
        :pf#190485:of#121144:bf#8192:ff#1024:\
        :pg#261876:og#49324:bg#8192:fg#1024:\
        :b0=rdboot:

With this knowledge we can start the disk label.

With this program you can modify everything in the on-disk
disklabel. To do something useful you must know the exact
geometry of your disk, and have ideas about how you want
your partitions to be placed on disk. Some hints:
The a partition should be at least ~20000 blocks, the
b (swap) is depending on your use of the machine but it
should almost never be less than ~32000 blocks.

Disk geometry for most DEC disks can be found in the disktab
file, and disknames is listed in the installation notes.

Remember that disk names is given as disk(adapt, ctrl, disk, part)
when using the installation tools.

This program will read miniroot from tape/floppy/disk
and install this miniroot onto disk.


Specify the device to read from as xx(N,?), where
xx is the device-name, ? is file/partition number
and N is the unit-number, e.g.
"tms(0,1)" for the first TMSCP-tape (TK50),
"ra(2,0)" for the third MSCP-disk/floppy (RX33/RX50)

device to read from ? tms(0,1)

Specify number of blocks to transfer. Usually this is
sizeof(miniroot) / 512.
It's safe to transfer more blocks than just the miniroot.

number of blocks ? 4096

If your miniroot is split into volumes, then you must
specify the number of blocks per volume.
(e.g. 800 blocks per RX50, 2400 blocks per RX33)

number of blocks per volume ? [4096]

Make sure unit tms(0,1) is online and holds the proper volume.
Then type 'g' to Go or 'a' to Abort.

OK to go on ? [g/a] g
Reading ... Reading of miniroot done. (4096 blocks read)


Now specify the device to write miniroot to as xx(N,1)
where xx is the drive type and N is the drive number.
For example: ra(0,1) refers to MSCP drive #0, b partition

Root disk ? : ra(1,1)
Initializing partition ... done.
(4096 blocks written.)

Halt the machine and reboot from distribution media,
giving second partition as part to mount as root. Ex:
: ra(0,1) for ra disk 0, hp(2,1) for massbuss disk 2

Halt/Reboot the machine NOW.
