Steps to convert SargeBook v5 to a system for 5MX
(Updated July 2006 with corrections for using the new kernel modules.)

(1) Delete /lib/modules/2.4.27-vrs1-kvd1
(2) Edit /etc/fstab 
    Change ext3 -> ext2 (for now)
    Comment out ramfs for /var/log, /var/cache/man
(3) Delete ttySA0, ttySA1
(4) Create ttyAM0, ttyAM1, tpanel
    mknod /dev/tpanel c 10 11
    mknod /dev/ttyAM0 c 204 16    [ IRDA serial port ]
    mknod /dev/ttyAM1 c 204 17    [ regular serial port ]

(5) Edit /etc/rc
    Comment out unpacking of varstuff
    Uncomment the fbset -a 2bpp
    Uncomment out the sleep idle lines at the end
(6) /etc/rc2.d
    Delete S12touchscreen, S01ram, S10sysklogd, S11klogd, S14ppp
     S20inetd, S20pcmcia, S20makedev
      (Comment out system logging - don't wear out your disk for
       that; not enough ram for ramfs /var/log, etc.)
(7) Unpack /etc/varstuff.tar to var; delete varstuff.tar
(8) Delete /etc/*old, rc~, motd~, passwd.org
(9) mkdir ../lib/modules/2.4.18-rmk6-5mx4, or appropriate name 
     according to which kernel you use.  Until recently Modules 
     were not used, and the kernel is happier if this directory 
     exists.  
     N.B. Recent kernels for download on sourceforge also require 
     the kernel modules to be installed for such things as vfat, ppp,
     and irda support.  Unpack the modules tarball to 
     /usr/lib/modules/ as required. 
(10) Remove pcmcia-cs package (if desired/if you can)
(11) Edit /etc/inittab:
     Comment out getty on ttySA0
     If desired, set getty on ttyAM1
     
(12) Edit /etc/fb.modes:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

   #Video modes for Psion 5mx

  mode "default"
   # D: 3472.222 MHz, H: 5425.347 kHz, V: 22605.613 Hz

   endmode

(13) Delete files in /root: Xipaq* pcmcia  scripts/fixstart

(14) Copy Xipaq X server to /usr/X11R6/bin/X
     And Xmodmap to /root/.Xmodmap.  See sourceforge Files.
     https://sourceforge.net/project/showfiles.php?group_id=8846
.Xmodmap:
keycode 71 = Shift_L
keycode 63 = Shift_R
keycode 47 = Control_L
keycode 55 = Mode_switch
keycode 39 = Alt_L
clear Lock
add Shift = Shift_L
add Shift = Shift_R
add Control = Control_L
add Mod1 = Alt_L
add Mod5 = Mode_switch

    Delete /etc/X11/XF86Config-4
    (Probably better off using a simple blackbox Window manager, particularly
    for grayscale colors.)

(15) The fbset at boot up will put the 5MX in 2bpp so that the text
     is more visibile.  Before starting X, first make sure you are 
     in 4bpp by fbset -a 4bpp ; otherwise a segmentation fault results.
     N.B. This is no longer required - the newer kernels don't have 
     this problem so 4 bpp can be the default.  See /etc/rc (maybe) to fix.
(16) Edit /usr/X11R6/lib/X11/xinit/xinitrc to double check it is set
     appropriately.  (Want to use a serial mouse?  Give the appropriate
     option here.)
