The size of this +partition must be 800KB and its partition type must be +<emphasis>Apple_Bootstrap</emphasis>. If the bootstrap partition is +not created with the <emphasis>Apple_Bootstrap</emphasis> type your +machine cannot be made bootable from the hard disk. This partition +can easily be created by creating a new partition in +<command>partman</command> and telling it to use it as a <quote>NewWorld +boot partition</quote>, or in <command>mac-fdisk</command> using the +<userinput>b</userinput> command. + +</para><para> + +The special partition type Apple_Bootstrap is required to prevent +MacOS from mounting and damaging the bootstrap partition, as there are +special modifications made to it in order for OpenFirmware to boot it +automatically. + +</para><para> + +Note that the bootstrap partition is only meant to hold 3 very small +files: the <command>yaboot</command> binary, its configuration +<filename>yaboot.conf</filename>, and a first stage OpenFirmware +loader <command>ofboot.b</command>.

The bootstrap partition should be +the first one you create. However, if you add a bootstrap partition +later, you can use <command>mac-fdisk</command>'s +<userinput>r</userinput> command to reorder the partition map so the +bootstrap partition comes right after the map (which is always +partition 1). It's the logical map order, not the physical address +order, that counts. + +</para><para> + +Apple disks normally have several small driver partitions. If you +intend to dual boot your machine with MacOSX, you should retain these +partitions and a small HFS partition (800k is the minimum size). That +is because MacOSX, on every boot, offers to initialize any disks which do +not have active MacOS partitions and driver partitions. + +</para> + </sect2> |
