prep revision 1.13
1You will need an AmigaDOS hard drive prep tool to prepare you hard 2drives for use with NetBSD/Amiga. HDToolBox is provided with the 3system software and on floppy installation disks since Release 2.0 4of AmigaDOS so we will provide instructions for its use. 5 6Preparing 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 The first time you partition a drive, you need to set its drive 12 type so that you have working geometry parameters. To do this 13 you enter the "Change drive type" menu, and either use "read 14 parameters from drive" or set them manually. 15 16 Note you will be modifying your HD's if you mess something 17 up here you could lose everything on all the drives that 18 you configure. It is therefore advised that you: 19 20 Write down your current configurations. Do this 21 by examining each partition on the drive and the 22 drives parameters (from Change drive type.) 23 24 Back up the partitions you are keeping. 25 26 What you need to do is partition your drives; creating at least 27 root, swap and /usr partitions and possibly at least one more for 28 /local if you have the space. 29 30 This should be done as the HDToolBox manual describes. One thing 31 to note is that if you are not using a Commodore controller you 32 will need to specify the device your SCSI controller uses e.g. 33 if you have a Warp Engine you would: 34 35 from cli, 36 hdtoolbox warpdrive.device 37 38 from wb set the tooltype, 39 SCSI_DEVICE_NAME=warpdrive.device 40 41 The important things you need to do above and beyond normal 42 partitioning includes (from Partition Drive section): 43 44 Marking all NetBSD partitions as non-bootable, with 45 two exceptions: the root partition, if you want to boot 46 NetBSD directly, or the swap partition, if you want 47 to boot the installation miniroot directly. 48 49 Changing the file system parameters of the partitions 50 to NetBSD ones. This must be done from the 51 partitioning section and `Advanced options' must 52 be enabled. To Make the needed changes: 53 54 - Click the `Adv. Options' button 55 - Click the `Change file system' button 56 57 - Choose `Custom File System' 58 - Turn off `Automount' if on. 59 - Set the dostype to one of these three choices: 60 61 root partition : 0x4e425207 62 swap partition : 0x4e425301 63 other partitions: 0x4e425507 64 65 Here `other' refers to other partitions you will 66 format for reading and writing under NetBSD (e.g. 67 /usr) 68 69 Make sure you hit the return key to enter this value 70 as some versions of HDToolBox will forget your entry 71 if you don't. 72 73 - Turn custom boot code off 74 - Set Reserved Blocks start and end to 0. 75 - Click Ok. 76 77 On the root (and, for installation, swap) partition, 78 set instead this: 79 80 - Turn custom boot code on 81 - Set Reserved Blocks start and end to 0. 82 - Set Number of Custom Boot Blocks to 16 83 - Set Automount This Partition on 84 - Click Ok. 85 86 Mask and maxtransfer are not used with NetBSD. 87 88 89 Once this is done NetBSD/Amiga will be able to recognize your 90 disks and which partitions it should use. 91 92Transferring the miniroot file system: 93 94 The NetBSD/Amiga installation or upgrade now uses a "miniroot" 95 file system which is installed on the partition used by NetBSD 96 for swapping. This removes the requirement of using a floppy 97 disk for the file system used by the installation or upgrade 98 process. It also allows more utilities to be present on the 99 file system than would be available when using an 880K floppy 100 disk. 101 102 Once the hard disk has been prepared for NetBSD, the miniroot 103 file system (miniroot.fs) is transferred to the swap 104 partition configured during the hard disk prep (or the existing 105 swap partition in the case of an upgrade). The xstreamtodev 106 utility provided in the "amiga/utilities" directory can be used 107 on AmigaDOS to transfer the file system for either a new 108 installation or an upgrade. The file system can also be 109 transferred on an existing NetBSD system for an update by 110 using dd. This should only be done after booting NetBSD 111 into single-user state. It may also be possible to shutdown 112 to single-user, providing that the single-user state processes 113 are not using the swap partition. 114 115 On AmigaDOS, the command: 116 xstreamtodev --input=miniroot.fs --rdb-name=<swap partition> 117 where <swap partition> is the name you gave to the NetBSD 118 partition to be used for swapping. If xstreamtodev is unable 119 to determine the SCSI driver device name or the unit number 120 of the specified partition, you may also need to include the 121 option "--device=<driver.name>" and/or "--unit=<SCSI unit number>". 122 123 To transfer the miniroot using NetBSD, you should be booted up 124 in single user state on the current NetBSD system, or use the 125 "shutdown now" command to shutdown to single-user state. Then 126 copy the miniroot using dd: 127 dd if=miniroot.fs of=/dev/rsd0b 128 where /dev/rsd0b should be the device path of the swap partition 129 your system is configured to use. Once the file is copied, 130 reboot back to AmigaDOS to boot the upgrade kernel. 131
