Updates to VA VistA Demo Toaster appliance: http://groups.google.com/group/Hardhats/browse_thread/thread/89ba7bbdf941b19?hl=en

Modifications to '''inetd''' configuration (courtesy KS BHaskar):
<pre>
To enable inetd to start automatically, 
execute each of the following commands once.  When you reboot your 
Toaster, inetd will start automatically: 

sudo ln -s /etc/init.d/inetd /etc/rc2.d/S20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc3.d/S20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc4.d/S20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc5.d/S20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc1.d/K20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc2.d/K20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc3.d/K20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc4.d/K20inetd 
sudo ln -s /etc/init.d/inetd /etc/rc5.d/K20inetd 
</pre>

Enhancement to automatically start and stop Taskaman (courtesy KS BHaskar):

<pre>
Edit the file /etc/init.d/VAVistADemo20060926 (e.g., with "sudo 
beaver /etc/init.d/VAVistADemo20060926" which gives you a WYSIWYG GUI 
editor), and make it look like this: 

---------------------------------------------- 
#!/bin/sh 

PATH=/bin:/usr/bin:/sbin:/usr/sbin 

source /usr/local/gtm_V5.2-000/gtmprofile 
cd /var/VAVistADemo20060926/gtm_V5.2-000 

case "$1" in 
  start) 
        sudo -u dsl /usr/local/gtm_V5.2-000/mupip journal -recover - 
backward g/mumps.mjl 
        sudo -u dsl ./run RESTART^ZTMB <<EOF 
Y 
EOF 
        ;; 
  stop) 
        sudo -u dsl ./run STOP^ZTMKU <<EOF 
Y 
Y 
EOF 
        sleep 5 
        sudo -u dsl killall mumps 
        sudo -u dsl /usr/local/gtm_V5.2-000/mupip journal -recover - 
backward g/mumps.mjl 
        ;; 
  *) 
        echo "Usage: /etc/init.d/VAVistADemo20060926 {start|stop}" 
        exit 1 
esac 

exit 0 
---------------------------------------------- 

Taskman will automatically start when you boot the Toaster, and shut 
down when you stop it. 
</pre>



*Guest launch scripting

Modifications: qemu-win.bat

The .bat file that comes with QEMU has been modified to launch Toaster.

The original file:
<pre>
REM Start qemu on windows.
@ECHO OFF
REM SDL_VIDEODRIVER=directx is faster than windib. But keyboard cannot work well.
SET SDL_VIDEODRIVER=windib
REM SDL_AUDIODRIVER=waveout or dsound can be used. Only if QEMU_AUDIO_DRV=sdl.
SET SDL_AUDIODRIVER=dsound
REM QEMU_AUDIO_DRV=dsound or fmod or sdl or none can be used. See qemu -audio-
help.
SET QEMU_AUDIO_DRV=dsound
REM QEMU_AUDIO_LOG_TO_MONITOR=1 displays log messages in QEMU monitor.
SET QEMU_AUDIO_LOG_TO_MONITOR=0
qemu.exe -L . -m 128 -hda linux.img -soundhw all -localtime
</pre>

The modified file: 
(UPDATED 01/28/06 - added 'net start kqemu' to launch QEMU Accelerator Module
<pre>
net start kqemu
REM Start qemu on windows.
@ECHO OFF
REM SDL_VIDEODRIVER=directx is faster than windib. But keyboard cannot work well.
SET SDL_VIDEODRIVER=windib
REM SDL_AUDIODRIVER=waveout or dsound can be used. Only if QEMU_AUDIO_DRV=sdl.
SET SDL_AUDIODRIVER=dsound
REM QEMU_AUDIO_DRV=dsound or fmod or sdl or none can be used. See qemu -audio-help.
SET QEMU_AUDIO_DRV=dsound
REM QEMU_AUDIO_LOG_TO_MONITOR=1 displays log messages in QEMU monitor.
SET QEMU_AUDIO_LOG_TO_MONITOR=0
qemu.exe -L . -m 128 -hda -soundhw all -localtime -redir tcp:2222::22 -redir tcp:9297::9297 VAVistADemo20060912.qcow
</pre>

== Client connection configuration ==

'''CPRS Connection'''
CPRS can connect to the appliance from the host with "CPRSChart s=127.0.0.1 p=9297 CCOW=DISABLE". 
*Above string stored in batch file. Batch file copied to CPRS directory.
*Windows Hosts file modifcation not required ('127.0.0.1 BROKERSERVER')
*When CPRS launches and connects with VistA serve, a sign-in screen appears. Use the Access and Verify codes: VistAis#1 and #1isVistA respectively. 

'''Guest architecture'''
*Guest loading scripting
**Start up / Shut down (/etc/init.d/) - 100%
**Start/stop TaskMan script applied - 100%
**Code review and optization - 15%
