You will need an AmigaDOS hard drive prep tool to prepare you hard
drives for use with NetBSD/amiga. HDToolBox is provided with the
system software and on floppy installation disks since Release 2.0
of AmigaDOS so we will provide instructions for its use.
Preparing you hard disk with HDToolBox:
A full explanation of HDToolBox can be found with your
AmigaDOS manuals and is beyond the scope of this document.
Note you will be modifying your HD's if you mess something
up here you could lose everything on all the drives that
you configure. It is therefore advised that you:
Write down your current configurations. Do this
by examining each partition on the drive and the
drives parameters (from Change drive type.)
Back up the partitions you are keeping.
What you need to do is partition your drives; creating
at least root, swap and /usr partitions and possibly at least
one more for /local if you have the space.
This should be done as the HDToolBox manual describes. One thing
to note is that if you are not using a Commodore controller you
will need to specify the device your SCSI controller uses e.g.
if you have a Warp Engine you would:
from cli,
hdtoolbox warpdrive.device
from wb set the tooltype,
SCSI_DEVICE_NAME=warpdrive.device
The important things you need to do above and beyond normal
partitioning includes (from Partition Drive section):
Marking all NetBSD partitions as non-bootable.
Changing the file system parameters of the partitions
to NetBSD ones. This must be done from the
partitioning section and `Advanced options' must
be enabled. To Make the needed changes:
- Click the `Adv. Options' button
- Click the `Change filesystem' button
- Choose `Custom File System'
- Turn off `Automount' if on.
- Set the dostype to one of these three choices:
root partition : 0x4e425207
swap partition : 0x4e425301
other partitions: 0x4e425507
Here `other' refers to other partitions you will
format for reading and writing under NetBSD (e.g.
/usr)
Make sure you hit the return key to enter this value
as some versions of HDToolBox will forget your entry
if you don't.
- Turn custom boot code off
- Set Reserved Blocks start and end to 0.
- Click Ok.
Mask and maxtransfer are not used with NetBSD.
Until you compile your own kernel your swap partition
must exist on the drive that also holds your root
partition.
Once this is done NetBSD/amiga will be able to recognize your
disks and which partitions it should use.
