prep revision 1.11 1 You will need an AmigaDOS hard drive prep tool to prepare you hard
2 drives for use with NetBSD/Amiga. HDToolBox is provided with the
3 system software and on floppy installation disks since Release 2.0
4 of AmigaDOS so we will provide instructions for its use.
5
6 Preparing you hard disk with HDToolBox:
7
8 A full explanation of HDToolBox can be found with your
9 AmigaDOS manuals and is beyond the scope of this document.
10
11 Note you will be modifying your HD's if you mess something
12 up here you could lose everything on all the drives that
13 you configure. It is therefore advised that you:
14
15 Write down your current configurations. Do this
16 by examining each partition on the drive and the
17 drives parameters (from Change drive type.)
18
19 Back up the partitions you are keeping.
20
21 What you need to do is partition your drives; creating at least
22 root, swap and /usr partitions and possibly at least one more for
23 /local if you have the space.
24
25 This should be done as the HDToolBox manual describes. One thing
26 to note is that if you are not using a Commodore controller you
27 will need to specify the device your SCSI controller uses e.g.
28 if you have a Warp Engine you would:
29
30 from cli,
31 hdtoolbox warpdrive.device
32
33 from wb set the tooltype,
34 SCSI_DEVICE_NAME=warpdrive.device
35
36 The important things you need to do above and beyond normal
37 partitioning includes (from Partition Drive section):
38
39 Marking all NetBSD partitions as non-bootable, with
40 one exception: the root partition, if you want to boot
41 NetBSD directly.
42
43 Changing the file system parameters of the partitions
44 to NetBSD ones. This must be done from the
45 partitioning section and `Advanced options' must
46 be enabled. To Make the needed changes:
47
48 - Click the `Adv. Options' button
49 - Click the `Change file system' button
50
51 - Choose `Custom File System'
52 - Turn off `Automount' if on.
53 - Set the dostype to one of these three choices:
54
55 root partition : 0x4e425207
56 swap partition : 0x4e425301
57 other partitions: 0x4e425507
58
59 Here `other' refers to other partitions you will
60 format for reading and writing under NetBSD (e.g.
61 /usr)
62
63 Make sure you hit the return key to enter this value
64 as some versions of HDToolBox will forget your entry
65 if you don't.
66
67 - Turn custom boot code off
68 - Set Reserved Blocks start and end to 0.
69 - Click Ok.
70
71 On the root (and, for installation, swap) partition,
72 set instead this:
73
74 - Turn custom boot code on
75 - Set Reserved Blocks start and end to 0.
76 - Set Number of Custom Boot Blocks to 16
77 - Set Automount This Partition on
78 - Click Ok.
79
80 Mask and maxtransfer are not used with NetBSD.
81
82
83 Once this is done NetBSD/Amiga will be able to recognize your
84 disks and which partitions it should use.
85
86 Transferring the miniroot file system:
87
88 The NetBSD/Amiga installation or upgrade now uses a "miniroot"
89 file system which is installed on the partition used by NetBSD
90 for swapping. This removes the requirement of using a floppy
91 disk for the file system used by the installation or upgrade
92 process. It also allows more utilities to be present on the
93 file system than would be available when using an 880K floppy
94 disk.
95
96 Once the hard disk has been prepared for NetBSD, the miniroot
97 file system (miniroot.fs) is transferred to the swap
98 partition configured during the hard disk prep (or the existing
99 swap partition in the case of an upgrade). The xstreamtodev
100 utility provided in the "amiga/utilities" directory can be used
101 on AmigaDOS to transfer the file system for either a new
102 installation or an upgrade. The file system can also be
103 transferred on an existing NetBSD system for an update by
104 using dd. This should only be done after booting NetBSD
105 into single-user state. It may also be possible to shutdown
106 to single-user, providing that the single-user state processes
107 are not using the swap partition.
108
109 On AmigaDOS, the command:
110 xstreamtodev --input=miniroot.fs --rdb-name=<swap partition>
111 where <swap partition> is the name you gave to the NetBSD
112 partition to be used for swapping. If xstreamtodev is unable
113 to determine the SCSI driver device name or the unit number
114 of the specified partition, you may also need to include the
115 option "--device=<driver.name>" and/or "--unit=<SCSI unit number>".
116
117 To transfer the miniroot using NetBSD, you should be booted up
118 in single user state on the current NetBSD system, or use the
119 "shutdown now" command to shutdown to single-user state. Then
120 copy the miniroot using dd:
121 dd if=miniroot.fs of=/dev/rsd0b
122 where /dev/rsd0b should be the device path of the swap partition
123 your system is configured to use. Once the file is copied,
124 reboot back to AmigaDOS to boot the upgrade kernel.
