You will need an AmigaDOS hard drive prep tool to prepare you hard drives for use with NetBSD/amiga. HDToolBox is provided with the system software and on floppy installation disks since Release 2.0 of AmigaDOS so we will provide instructions for its use. Preparing you hard disk with HDToolBox: A full explanation of HDToolBox can be found with your AmigaDOS manuals and is beyond the scope of this document. Note you will be modifying your HD's if you mess something up here you could lose everything on all the drives that you configure. It is therefore advised that you: Write down your current configurations. Do this by examining each partition on the drive and the drives parameters (from Change drive type.) Back up the partitions you are keeping. What you need to do is partition your drives; creating at least root, swap and /usr partitions and possibly at least one more for /local if you have the space. This should be done as the HDToolBox manual describes. One thing to note is that if you are not using a Commodore controller you will need to specify the device your SCSI controller uses e.g. if you have a Warp Engine you would: from cli, hdtoolbox warpdrive.device from wb set the tooltype, SCSI_DEVICE_NAME=warpdrive.device The important things you need to do above and beyond normal partitioning includes (from Partition Drive section): Marking all NetBSD partitions as non-bootable. Changing the file system parameters of the partitions to NetBSD ones. This must be done from the partitioning section and `Advanced options' must be enabled. To Make the needed changes: - Click the `Adv. Options' button - Click the `Change filesystem' button - Choose `Custom File System' - Turn off `Automount' if on. - Set the dostype to one of these three choices: root partition : 0x4e425207 swap partition : 0x4e425301 other partitions: 0x4e425507 Here `other' refers to other partitions you will format for reading and writing under NetBSD (e.g. /usr) Make sure you hit the return key to enter this value as some versions of HDToolBox will forget your entry if you don't. - Turn custom boot code off - Set Reserved Blocks start and end to 0. - Click Ok. Mask and maxtransfer are not used with NetBSD. Until you compile your own kernel your swap partition must exist on the drive that also holds your root partition. Once this is done NetBSD/amiga will be able to recognize your disks and which partitions it should use.
