machine independent portion of this implementation of +.Nm +was written by Luke Mewburn. +The following people contributed to the various machine dependent +back-ends: +Simon Burge (pmax), +Chris Demetriou (alpha), +Matthew Fredette (sun2, sun3), +Matthew Green (sparc64), +Ross Harvey (alpha), +Michael Hitch (amiga), +Paul Kranenburg (sparc), +David Laight (i386), +Christian Limpach (next68k), +Luke Mewburn (macppc), +Matt Thomas (vax), +Izumi Tsutsui (news68k, newsmips), +and +UCHIYAMA Yasushi (ews4800mips). +. +.Sh BUGS +There are not currently primary bootstraps to support all file systems +types which are capable of being the root file system. +.Pp +If a disk has been converted from +.Sy FFS +to +.Sy RAID +without the contents of the disk erased, then the original +.Sy FFS +installation may be auto-detected instead of the +.Sy RAID +installation. +In this case, the +.Fl t Ar raid +option must be provided. +. +.Ss Nx Ns Tn /alpha +The +.Nx Ns Tn /alpha +primary bootstrap program can only load the secondary bootstrap program +from file systems starting at the beginning (block 0) of disks. +Similarly, the secondary bootstrap program can only load kernels from +file systems starting at the beginning of disks. +.Pp +The size of primary bootstrap programs is restricted to 7.5KB, even +though some file systems (e.g., ISO 9660) are able to accommodate larger +ones. +. +.Ss Nx Ns Tn /hp300 +The disk must have a boot partition large enough to hold the bootstrap code. +Currently the primary bootstrap must be a LIF format file. +. +.Ss Nx Ns Tn /i386 and Nx Ns Tn /amd64 +The bootstrap must be installed in the +.Nx +partition that starts at the beginning of the mbr partition. +If that is a valid filesystem and contains the +.Pa /boot +program then it will be used as the root filesystem, otherwise the +.Sq a +partition will be booted. +.Pp +The size of primary bootstrap programs is restricted to 8KB, even +though some file systems (e.g., ISO 9660) are able to accommodate larger +ones. +. +.Ss Nx Ns Tn /macppc +Due to restrictions in +.Nm +and the secondary bootstrap implementation, file systems where kernels exist +must start at the beginning of disks. +.Pp +Currently, +.Nm +doesn't recognize an existing Apple partition map on the disk +and always writes a faked map to make disks bootable. +.Pp +The +.Nx Ns Tn /macppc +bootstrap program can't load kernels from +.Sy FFSv2 +partitions. +.Ss Nx Ns Tn /next68k +The size of bootstrap programs is restricted to the free space before +the file system at the beginning of the disk minus 8KB. +. +.Ss Nx Ns Tn /pmax +The +.Nx Ns Tn /pmax +secondary bootstrap program can only load kernels from file +systems starting at the beginning of disks. +.Pp +The size of primary bootstrap programs is restricted to 7.5KB, even +though some file systems (e.g., ISO 9660) are able to accommodate larger +ones. +. +.Ss Nx Ns Tn /sun2 and Nx Ns Tn /sun3 +The +.Nx Ns Tn /sun2 +and +.Nx Ns Tn /sun3 +secondary bootstrap program can only load kernels from file +systems starting at the beginning of disks. +. +.Ss Nx Ns Tn /vax +The +.Nx Ns Tn /vax +secondary bootstrap program can only load kernels from file
