prep revision 1.9
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 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. (The root and swap partitions must 24 be on the same drive for your initial installation. You can use 25 other configurations after building a customized kernel once your 26 system is running.) 27 28 This should be done as the HDToolBox manual describes. One thing 29 to note is that if you are not using a Commodore controller you 30 will need to specify the device your SCSI controller uses e.g. 31 if you have a Warp Engine you would: 32 33 from cli, 34 hdtoolbox warpdrive.device 35 36 from wb set the tooltype, 37 SCSI_DEVICE_NAME=warpdrive.device 38 39 The important things you need to do above and beyond normal 40 partitioning includes (from Partition Drive section): 41 42 Marking all NetBSD partitions as non-bootable, with 43 one exception: the root partition, if you want to boot 44 NetBSD directly. 45 46 Changing the file system parameters of the partitions 47 to NetBSD ones. This must be done from the 48 partitioning section and `Advanced options' must 49 be enabled. To Make the needed changes: 50 51 - Click the `Adv. Options' button 52 - Click the `Change file system' button 53 54 - Choose `Custom File System' 55 - Turn off `Automount' if on. 56 - Set the dostype to one of these three choices: 57 58 root partition : 0x4e425207 59 swap partition : 0x4e425301 60 other partitions: 0x4e425507 61 62 Here `other' refers to other partitions you will 63 format for reading and writing under NetBSD (e.g. 64 /usr) 65 66 Make sure you hit the return key to enter this value 67 as some versions of HDToolBox will forget your entry 68 if you don't. 69 70 - Turn custom boot code off 71 - Set Reserved Blocks start and end to 0. 72 - Click Ok. 73 74 On the root (and, for installation, swap) partition, 75 set instead this: 76 77 - Turn custom boot code on 78 - Set Reserved Blocks start and end to 0. 79 - Set Number of Custom Boot Blocks to 16 80 - Set Automount This Partition on 81 - Click Ok. 82 83 Mask and maxtransfer are not used with NetBSD. 84 85 Until you compile your own kernel your swap partition 86 must exist on the drive that also holds your root 87 partition. 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 appropriate 104 miniroot file system (inst-12.fs for a new install or upgr-12.fs 105 for an upgrade) is transferred to the swap partition configured 106 during the hard disk prep (or the existing swap partition in 107 the case of an upgrade). The xstreamtodev utility provided in 108 the "amiga/utilities" directory can be used on AmigaDOS to 109 transfer the file system for either a new installation or an 110 upgrade. The file system can also be transferred on an existing 111 NetBSD system for an update by using dd. This should only be 112 done after booting NetBSD into single-user state. It may also 113 be possible to shutdown to single-user, providing that the 114 single-user state processes are not using the swap partition. 115 116 On AmigaDOS, the command: 117 xstreamtodev --input=inst-12.fs --rdb-name=<swap partition> 118 where <swap partition> is the name you gave to the NetBSD 119 partition to be used for swapping. Use upgr-12.fs if you 120 are going to do an upgrade of an existing NetBSD system. If 121 xstreamtodev is unable to determine the SCSI driver device 122 name or the unit number of the specified partition, you may 123 also need to include the option "--device=<driver.name>" and/or 124 "--unit=<SCSI unit number>". 125 126 To transfer the miniroot using NetBSD, you should be booted up 127 in single user state on the current NetBSD system, or use the 128 "shutdown now" command to shutdown to single-user state. Then 129 copy the miniroot using dd: 130 dd if=upgr-12.fs of=/dev/rsd0b 131 where /dev/rsd0b should be the device path of the swap partition 132 your system is configured to use. Once the file is copied, 133 reboot back to AmigaDOS to boot the upgrade kernel. NOTE: the 134 release kernel is a "generic" kernel, and requires that the 135 swap partition be on the same device as the root partition. 136
