Power requirements

The Ziatech PCs do need 12V.

Preparing a Ziatech ZT5521-1a for netbooting noe 2000/08/01

  o   Unpack and install in a crate that contains either
       - a floppy drive  (e.g. the Amanda crates can do that (floppy on the right
         side!))
       - a harddrive with a NetBoot linux kernel (see e.g. the 5512 internal harddrives)
         (see note 1 at end )
  o   Think about a clever hostname for the machine that is used for 
      booting and standalone use (e.g. host21).
      (the names unitXY are used internally in APEmille, don't use one of
      these here)
  o   If using a floppy, produce a netboot floppy using the image in 
      /apeboot/netboot/  . See README there.
  o   Boot either from floppy or hard disk. (Adjust the boot sequence in the
      BIOS if necessary).
      The ziatech will then remain in BOOTP mode and send requests until 
      receiving a reply.
  o   Install a bootp server for the hardware address shown on the ziatech 
      display so that the ziatech will net-boot into DOS 
      (bootfile=bootImage-dos)
      - If doing this on the same subnet as apemaster, simply add an 
        entry to /etc/bootptab using the correct IP number and name. See the
        examples already there.
      - If not, install a 'routing server' somewhere else (e.g. pionkl 
        seems to work on subnet 2) using a /etc/bootptab entry like
        ziatmp:\
        :hd=/apeboot:\
        :ip=141.34.2.244:\		# unused address !!!
        :ha=00805001e401:\		# the HW address
        :bf=images/bootImage-dos:\	# boot ms-dos
        :rp=/apeboot/:\			# (ignored)
        :sa=141.34.40.40:\		# where to load it from -> apemaster
        :gw=141.34.2.1:\
        :sm=255.255.255.0:\
        :ht=ethernet:\
	:ds=141.34.1.22 141.34.1.16 131.169.200.2:\
	:vm=auto:

        (remember to enable bootp in /etc/inetd.conf and HUP inetd)
	The ziatech will now get it's bootp information from your
        'routing-server' but will load all files from apemaster.
   o   The Ziatech should now boot into MS-DOS. (Reset if it has gone into
       timeout already).

       <automatic reboot)
       After the reboot , adjust the settings in /etc/bootptab like for
       the other entries, so it will boot Linux instead of DOS.
       Add the new host to apemaster:/etc/hosts and 
       apemaster:/apeboot/rh60/root/etc/hosts.local (if on intranet)
       Configure a new root-directory for the new host : 
         cd  /apeboot/rh60/
         ./newhost <hostname>

       (possible problem: ssh host keys, adjust /apeboot/fixed/ if
        necessary)
       Edit apemaster:/etc/exports to enable mounting the root-disk, the
       /usr disk and all other needed disks and do a '/usr/sbin/kexportfs -r'
       Try a reboot of the ziatech....
 Notes:
   1) it can also be a valid DOS harddisk. But then you'll need to fetch the
      michelo.rom and flash.exe files from /apeboot/netboot/
      If there's a valid Linux on the harddisk you can install 
      /apeboot/netboot/netImage as an additional Linux kernel and boot it.
