====== Compaq Evo T30 ======




===== Introduction =====
The [[http://h18004.www1.hp.com/products/quickspecs/11058_div/11058_div.HTML | Compaq Evo T30]] is a thin client.  One day, while shopping at [[http://weirdstuff.com | Weird Stuff]], I happened to pick up several of these for a great price.  About half didn't boot, but I think this is because they don't have a plugin memory card.  My goal is to install Linux on them.

The ones I have don't appear to be a standard version:
  * Model No.: T30
  * Part No.: 238622-001
  * Spare No.: 292238-001
  * Date Manufactured: November 2002
  * Licenced for Windows CE.NET v4.0

From powering up into the OS:
  * RAM: 64MB
  * Flash Memory, Device 1: 32MB

From cracking the case:
  * National Geode CS5530A-UCE (this is the southbridge, now made by AMD)
  * Geode processor under heat sink on bottom of board

This suggests the model I have is similar to the 238617-xxx (DK408A)

===== Power Up Sequence =====

Using a 12V power supply, 500mA is drawn after applying power.  The LED is orange and will flash once before turning off.  After a short period, the LED turns off and current draw drops to 300mA.  Pressing the button for about 3 seconds will make the LED green and will return the current draw to 500mA.

===== Actual Steps =====
==== Preparation ====

Using the [[http://thunderlord.net.pl/evo/ | WinCE.NET T20 instructions]] I prepared as follows:
  * Got the [[an>evo/sp22454.exe | Evo T20 and T30 Netxfer Tool for Loading Firmware 2.18 A 9 Oct 2002]] from [[http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12454&prodSeriesId=96324&prodNameId=97153&swEnvOID=1054&swLang=13&mode=2&taskId=135&swItem=PSG_I16129-38624 | HP]] -- this isn't needed.
  * Got [[an>evo/netxfer.sh]] from http://thunderlord.net.pl/evo/files/netxfer.sh
  * Got the [[an>evo/sp27933.exe | Evo T30 32/64 Rapport Package to Add CE.NET Firmware 4.0 B472.6 29 Apr 2004]] from [[http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12454&prodSeriesId=96324&prodNameId=97153&swEnvOID=1054&swLang=13&mode=2&taskId=135&swItem=PSG_I20941-104856 | HP]]


==== Initial Firmware Download ====
Set up for initial transfer of standard firmware:
  * Make /tmp/evo and chmod 777.
  * Execute sp27933.exe (under vmware) and copy ''Rapport_4.X/Push_472-6-14-6Cme7D_T30_CEN/P472_6_14_6_Cme7D.bin'' to /tmp/evo/bootp.bin
  * ''/etc/init.d/tftpd stop''
  * ''apt-get install dhcp3-server''
  * Edit ''netxfer.sh'' to change all /home/blah to /tmp/evo.
  * Power up the Evo T30 while pressing the 'p' key (while the LED is orange), getting to the screen shown above.
  * sh ''netxfer.sh'' (I tried with my normal dhcpd and tftp setup, but that's not good enough.  We need to be running on special ports for the Evo to communicate -- these ports are set up by this script.  I did not have to configure any special IP addresses.)
  * After the servers started and a few seconds passed, the T30 started printing stuff.
    * If you get the "error: not a tagged image" error, you might have used sp27933.exe directly instead of extracting its contents.
    * If you get errors about how the file cannot be read, perhaps you didn't chmod the file.
  * The T30 printed a lot of stuff and rebooted itself.  It ended up in a configuration utility, and I played around and set up a 1024x768 mode.  It then rebooted itself again.


==== Generate a new firmware ====
This section follows the [[http://thunderlord.net.pl/evo/ | preparing new firmware instructions]] noted above:
  * Get [[an>evo/fw_builder.tar.gz]] from http://thunderlord.net.pl/evo/files/fw_builder.tar.gz
  * Untar and put the original firmware from the last step into the ''fw_builder''.  Name it ''orig.bin''
  * ''apt-get install bin86''
  * ''./createfw''
  * Note the new file ''../bootp.bin''
  * Then power up while pressing 'p', as above.  This time, the process has different messages and goes faster, almost immediately rebooting into Linux.
