1 $NetBSD: prep,v 1.16 1998/09/27 19:32:59 is Exp $ 2 3You will need an AmigaDOS hard drive prep tool to prepare your hard 4drives for use with NetBSD/Amiga. HDToolBox is provided with the 5system software and on floppy installation disks since Release 2.0 6of AmigaDOS, so we will provide instructions for its use. 7 8Preparing you hard disk with HDToolBox: 9 10 A full explanation of HDToolBox can be found with your 11 AmigaDOS manuals and is beyond the scope of this document. 12 13 The first time you partition a drive, you need to set its drive 14 type so that you have working geometry parameters. To do this 15 you enter the "Change drive type" menu, and either use "read 16 parameters from drive" or set them manually. 17 18 Note you will be modifying your HD's. If you mess something 19 up here you could lose everything on all the drives that 20 you configure. It is therefore advised that you: 21 22 Write down your current configurations. Do this 23 by examining each partition on the drive and the 24 drives parameters (from Change drive type.) 25 26 Back up the partitions you are keeping. 27 28 What you need to do is partition your drives; creating at least 29 root, swap and /usr partitions and possibly at least one more for 30 /usr/local if you have the space. 31 32 This should be done as the HDToolBox manual describes. One thing 33 to note is that if you are not using a Commodore controller you 34 will need to specify the device your SCSI controller uses, e.g. 35 if you have a Warp Engine you would: 36 37 from cli, 38 hdtoolbox warpdrive.device 39 40 from wb set the tooltype, 41 SCSI_DEVICE_NAME=warpdrive.device 42 43 The important things you need to do above and beyond normal 44 partitioning includes (from Partition Drive section): 45 46 Marking all NetBSD partitions as non-bootable, with 47 two exceptions: the root partition, if you want to boot 48 NetBSD directly, or the swap partition, if you want 49 to boot the installation miniroot directly. 50 51 Changing the file system parameters of the partitions 52 to NetBSD ones. This must be done from the 53 partitioning section and `Advanced options' must 54 be enabled. To Make the needed changes: 55 56 - Click the `Adv. Options' button 57 - Click the `Change file system' button 58 - Choose `Custom File System' 59 - Turn off `Automount' if on. 60 - Set the dostype to one of these three choices: 61 62 root partition : 0x4e425207 63 swap partition : 0x4e425301 64 other partitions: 0x4e425507 65 66 Here `other' refers to other partitions you will 67 format for reading and writing under NetBSD (e.g. 68 /usr) 69 70 Make sure you hit the return key to enter this value 71 as some versions of HDToolBox will forget your entry 72 if you don't. 73 74 - Turn custom boot code off 75 - Set Reserved Blocks start and end to 0. 76 - Click Ok. 77 78 On the root (and, for installation, swap) partition, 79 set instead this: 80 81 - Turn custom boot code on 82 - Set Reserved Blocks start and end to 0. 83 - Set Number of Custom Boot Blocks to 16 84 - Set Automount This Partition on 85 - Click Ok. 86 87 Mask and maxtransfer are not used with NetBSD. 88 89 90 Once this is done NetBSD/Amiga will be able to recognize your 91 disks and which partitions it should use. 92 93Transferring the miniroot file system: 94 95 The NetBSD/Amiga installation or upgrade now uses a "miniroot" 96 file system which is installed on the partition used by NetBSD 97 for swapping. This removes the requirement of using a floppy 98 disk for the file system used by the installation or upgrade 99 process. It also allows more utilities to be present on the 100 file system than would be available when using an 880K floppy 101 disk. 102 103 Once the hard disk has been prepared for NetBSD, the miniroot 104 file system (miniroot.fs) is transferred to the swap 105 partition configured during the hard disk prep (or the existing 106 swap partition in the case of an upgrade). The xstreamtodev 107 utility provided in the "amiga/installation/misc" directory can 108 be used on AmigaDOS to transfer the file system for either a new 109 installation or an upgrade. The file system can also be 110 transferred on an existing NetBSD system for an update by 111 using dd. This should only be done after booting NetBSD 112 into single-user state. It may also be possible to shutdown 113 to single-user, providing that the single-user state processes 114 are not using the swap partition. 115 116 On AmigaDOS, the command: 117 xstreamtodev --input=miniroot.fs --rdb-name=<swap partition> 118 where <swap partition> is the name you gave to the NetBSD 119 partition to be used for swapping. If xstreamtodev is unable 120 to determine the SCSI driver device name or the unit number 121 of the specified partition, you may also need to include the 122 option "--device=<driver.name>" and/or "--unit=<SCSI unit number>". 123 124 To transfer the miniroot using NetBSD, you should be booted up 125 in single user state on the current NetBSD system, or use the 126 "shutdown now" command to shutdown to single-user state. Then 127 copy the miniroot using dd: 128 dd if=miniroot.fs of=/dev/rsd0b 129 where /dev/rsd0b should be the device path of the swap partition 130 your system is configured to use. Once the file is copied, 131 reboot back to AmigaDOS to boot the upgrade kernel. 132 133 CAVEAT: Once you have started installation once, whenever you abort it 134 and want to retry, you must reinstall the miniroot.fs on the swap 135 partition. 136
