NOTE: These instructions are explicitly for installing NetBSD
|
||
from an HP-UX system, version 7 or later. It has not been
|
||
tested with HP-UX versions earlier than 7, and has also not
|
||
been tested with HP-UX 8, although it is presumed to work.
|
||
For the creative, similar steps may be taken from a system such
|
||
as Utah's 4.3BSD release for the hp300, although bootstrapping
|
||
from such a system has not been tested.
|
||
|
||
Bootstrapping the hp300 is a complicated process, but it's a lot
|
||
easier than it used to be. For this process you need the
|
||
following items from the install/ directory:
|
||
|
||
boot NetBSD/hp300 boot block for
|
||
HP-IB and SCSI disks
|
||
|
||
rootimage.gz bootstrap root filesystem
|
||
image
|
||
|
||
label prototype disk label
|
||
|
||
makedisk a program for HP-UX that will
|
||
write a NetBSD disk label,
|
||
boot block, and root filesystem
|
||
image to the target disk
|
||
(NOTE: This is an HP-UX 7.x binary.
|
||
while it will work under HP-UX 9.x,
|
||
you may want to compile this yourself.
|
||
The source may be found in makedisk.tar.gz)
|
||
|
||
VERY IMPORTANT NOTE: This procedure will destroy all data on the
|
||
target disk. Because NetBSD uses a different filesystem format than
|
||
HP-UX, your old data will be useless. If you wish to save anything,
|
||
use tar(1) instead of dump(1M), again because of filesystem differences.
|
||
|
||
First of all, you must have a second disk on which to install NetBSD.
|
||
If possible, this disk should first be prepared with mediainit(1M).
|
||
Once this disk is spotless, you should generate a disk label for it.
|
||
Using the prototype label provided, fill in all of the necessary
|
||
information. Remember, if you derive geometry information from an
|
||
HP-UX disktab, your partition size will be off. This is because HP-UX
|
||
uses a 1024-byte sector size, while NetBSD uses a 512-byte sector size.
|
||
To avoid the problem, you may simply double the number of cylinders.
|
||
(That's what I do...works great. -- JRT)
|
||
|
||
IMPORTANT: Partition 'a' must be offset one cylinder. Since
|
||
partition information is expressed in sectors, the offset of
|
||
partition 'a' must be the value of `sectors/cylinder'. This is
|
||
to leave room for the boot block.
|
||
|
||
When you create your disklabel, be sure to specify whether or not
|
||
the disk is HP-IB or SCSI in the `type:' field.
|
||
|
||
Below is an example of what a disk label should look like. This
|
||
is an example only! Do not attempt this at home!
|
||
|
||
|
||
|
||

7 partitions:
|
||
# size offset fstype [fsize bsize cpg]
|
||
a: 30744 252 4.2BSD 1024 8192 16 # (Cyl. 1 - 122)
|
||
b: 32760 30996 swap # (Cyl. 123 - 252)
|
||
c: 255276 0 boot # (Cyl. 0 - 1012)
|
||
e: 20412 63756 4.2BSD 1024 4096 16 # (Cyl. 253 - 333)
|
||
f: 40824 84168 4.2BSD 1024 8192 16 # (Cyl. 334 - 495)
|
||
g: 130284 124992 4.2BSD 1024 8192 16 # (Cyl. 496 - 1012)
|
||
|
||
NOTE: Due to the nature of the bootstrapping procedure, your 'a'
|
||
partition must be at least 30744 sectors long. Increase the size of
|
||
your 'a' partition just enough to make it end on a cylinder boundary.
|
||
If you make it any larger, you will just be wasting space, as the
|
||
filesystem ends after 30744 sectors.
|
||
|
||
Remember to write down the names of the partitions and what you
|
||
will be using them for (i.e. 'a - root, b - swap, e - /usr, etc.')
|
||
as you will need this information later on in the installation
|
||
process.
|
||
|
||
Once you are satisfied with your disklabel, you can write the
|
||
root filesystem image to the target disk. Use the `makedisk'
|
||
program for this. So, under HP-UX, do:
|
||
|
||
./makedisk /dev/rdsk/c7d0s0 mylabel boot rootimage.gz
|
||
|
||
where:
|
||
/dev/rdsk/c7d0s0 raw flavor of target disk device
|
||
|
||
mylabel disk label you just wrote
|
||
|
||
boot supplied boot block
|
||
|
||
rootimage.gz gzipped root filesystem image
|
||
NOTE: This requires that gzip be
|
||
installed on your HP-UX system.
|
||
If it is not, a gzip binary is
|
||
provided in the install/ directory.
|
||
Source for gzip may be found in the
|
||
gsrc10 distribution set. Again, this
|
||
gzip is an HP-UX 7.x binary.
|
||
|
||
If you wish to label any additional disks, you will have to do this
|
||
from NetBSD, although you will not have an editor at your disposal.
|
||
To do this, simply generate the labels now, and then grab them at
|
||
the same time and by the same method you use to grab the distrubtion
|
||
sets.
|
||
|
||
Once this is done, you should be ready to boot NetBSD from the target
|
||
disk.
