My tree had some stale directories that needed cleaning:
  - cd /sys/src/cmd && rm 6? 9? rtstats
  - In between builds /sys/src/cmd/cc doesnt clean several
     libraries.  The should be manually removed if you want
     a clean rebuild:
         9/boot/libboot.a?
         cmd/cc/cc.a?
         cmd/map/libmap/libmap.a?
         cmd/plot/libplot.a?
         cmd/postscript/common/com.a?
         cmd/upas/common/libcommon.a?
         cmd/usb/lib/usb.a?

To build:
  - mount your root drive and extract the files
    - disk/kfscmd allow
    - 9fs kfs
    - cd /n/kfs
    - tar -x < $home/sparc64src.tar
  - build the cross compilers
    - for(d in ua ul uc) { cd /sys/src/cmd/$d && mk install }
    - cd /sys/src/ape/cmd && mk cc.install
    - cd /sys/src/cmd && mk pcc.install 
  - build the libraries and binaries
    - cd /sys/src
    - objtype=sparc64 mk install
  - build the kernel
    - cd /sys/src/9/sparc64
    - mk install
  - optionally rebuild your cross platform
    - cd /sys/src && mk install

To run:
  - make all binaries on a file server
  - setup for net booting with tftpd and rarpd running
  - connect a serial line to ttyA (uart #3) of the ultrasparc box.
     The default baud is 9600, but you may alter the
     speed with a command line option:
        console="3 b19200 l8 pn s1".
  - from the open firmware prompt run "boot net".  
     Arguments can be added to the end
     of the boot command if desired.
  - continue net booting as normal
  - scsi support's in now.
     to partition the drive use the disk/prep utility on
     the /dev/sd??/data partition.  The prep label will
     be read back during the boot process.
     Note: I've had to leave some empty space at the
     start of my disk to keep the table from getting clobbered.
     I havent investigated this further yet.  I recommend
     starting the first partition at offset 63 for now.
     You cant boot the kernel off disk yet (although you
     probably can boot it off a cdrom -- I havent tried yet),
     however you can use the disk as a local root filesystem
     after the kernel boots.  Adjust the kernel config file 
     to pick the partition you wish to use.
  - To simplify booting, you can configure ofw.  Setting the
     boot-device variable sets the devices to boot from.  Setting
     boot-file sets the command line arguments:
        {0} ok setenv boot-device net disk
        {0} ok setenv boot-device console="3 b19200 l8 pn s1" venti=#S/sd01/arenas0
        {0} printenv
        {0} boot


Updating:
  - if you installed an earlier version of this distribution you
     should remove /sys/src/cmd/K[cal].  The compiler tools are
     now named u[acl].
  - If you had installed a previous version there are files
     which were modified which are no longer needed.  You should
     restore the following files from sources:
         replica/pull -s -v sys/src/cmd/strip.c \
                 sys/src/libmach \
                 sys/include \
                 sys/lib/acid \
                 386/lib/libmach.a \
                 386/bin/^(acid ar strip size) \
                 sparc64
