prep revision 1.4
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 22 at least root, swap and /usr partitions and possibly at least 23 one more for /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. 40 41 Changing the file system parameters of the partitions 42 to NetBSD ones. This must be done from the 43 partitioning section and `Advanced options' must 44 be enabled. To Make the needed changes: 45 46 - Click the `Adv. Options' button 47 - Click the `Change filesystem' button 48 49 - Choose `Custom File System' 50 - Turn off `Automount' if on. 51 - Set the dostype to one of these three choices: 52 53 root partition : 0x4e425207 54 swap partition : 0x4e425301 55 other partitions: 0x4e425507 56 57 Here `other' refers to other partitions you will 58 format for reading and writing under NetBSD (e.g. 59 /usr) 60 61 Make sure you hit the return key to enter this value 62 as some versions of HDToolBox will forget your entry 63 if you don't. 64 65 - Turn custom boot code off 66 - Set Reserved Blocks start and end to 0. 67 - Click Ok. 68 69 Mask and maxtransfer are not used with NetBSD. 70 71 Until you compile your own kernel your swap partition 72 must exist on the drive that also holds your root 73 partition. 74 75 76 Once this is done NetBSD/amiga will be able to recognize your 77 disks and which partitions it should use. 78 79Transferring the miniroot filesystem: 80 81 The NetBSD/amiga installation or upgrade now uses a "miniroot" 82 fileystem which is installed on the partition used by NetBSD 83 for swapping. This removes the requirement of using a floppy 84 disk for the filesystem used by the installation or upgrade 85 process. It also allows more utilities to be present on the 86 filesystem than would be available when using an 880K floppy 87 disk. 88 89 Once the hard disk has been prepared for NetBSD, the appropriate 90 miniroot filesystem (inst-11.fs for a new install or upgr-11.fs 91 for an upgrade) is transferred to the swap partition configured 92 during the hard disk prep (or the existing swap parition in 93 the case of an upgrade). The xstreamtodev utility provided in 94 the "amiga/utilities" directory can be used on AmigaDOS to 95 transfer the filesystem for either a new installation or an 96 upgrade. The filesystem can also be transferred on an existing 97 NetBSD system for an update by using dd. This should only be 98 done after booting NetBSD into single-user state. It may also 99 be possible to shutdown to single-user, providing that the 100 single-user state processes are not using the swap partition. 101 102 On AmigaDOS, the command: 103 xstreamtodev --input=inst-11.fs -rdb-name=<swap partition> 104 where <swap partition> is the name you gave to the NetBSD 105 partition to be used for swapping. Use upgr-11.fs if you 106 are going to do an upgrade of an existing NetBSD system. If 107 xstreamtodev is unable to determine the SCSI driver device 108 name or the unit number of the specified partition, you may 109 also need to include the option "-device=<driver.name>" and/or 110 "-unit=<SCSI unit number>". 111 112 To transfer the miniroot using NetBSD, you should be booted up 113 in single user state on the current NetBSD system, or use the 114 "shutdown now" command to shutdown to single-uyser state. Then 115 copy the miniroot using dd: 116 dd if=upgr-11.fs of=/dev/rsd0b 117 where /dev/rsd0b should be the device path of the swap partition 118 your system is configured to use. Once the file is copied, 119 reboot back to AmigaDOS to boot the upgrade kernel. NOTE: the 120 release kernel is a "generic" kernel, and requires that the 121 swap partition be on the same device as the root partition. 122
