====== Michael Decker: Driver Development ======
===== Overview =====
My goals for the summer are:
  - To update a legacy Etherboot driver to the gPXE API
  - To port a Linux driver to gPXE

===== Status Log =====
The following is a log of steps I've taken.  Note that I don't use Linux on a daily basis.  Any terminal commands below are for my reference.
  * Installed libc6-dev, mtools, syslinux, & gitk with Synaptic Program Manager (SPM) 
  * Cloned git tree into samba share <code>$ git clone git://git.etherboot.org/scm/gpxe.git</code>
  * Successfully built gpxe <code>$ make</code>
  * Wrote to usb key, booted successfully on target <code>$ dd if=bin/gpxe.usb of=/dev/sdb</code>
  * Installed dhcp3-server via SPM and configured
    * Added interface to ''/etc/default/dhcp3-server'' <code>INTERFACES="eth0"</code>
    * Modified ''/etc/dhcp3/dhcpd.conf'' <code>
# dhcpd.conf
#

ddns-update-style none;
not authoritative;

default-lease-time 600;
max-lease-time 7200;

host h1 { 
  hardware ethernet 00:11:d8:0e:93:7b; 
}

host h2 {
  hardware ethernet 00:30:84:31:8f:b0;
}

shared-network "net" {
subnet 192.168.2.0 netmask 255.255.255.0 {
  range 192.168.2.10 192.168.2.20;
  option subnet-mask 255.255.255.0;
  option routers 192.168.2.1;
  deny unknown-clients;

  option root-path "192.168.2.1:/tftpboot";
  filename "test";
}
}</code> This configuration was made utilizing [[:twodhcpservers|this page]] and [[http://linux.die.net/man/5/dhcpd.conf|man dhcpd.conf]].  Hosts ''h1'' and ''h2'' are two different ethernet ports on the target.  After making changes: <code>$ /etc/init.d/dhcp3-server restart</code>
  * Installed tftpd-hpa via SPM and configured
    * Created ''/tftpboot'' directory
    * Modified ''/etc/inetd.conf'' <code>tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /tftpboot</code>
  * :!: Install HTTP server.
  * :!: Play with git.

===== Build Environment ===== 
Consists of three machines: A target client, a development server, and a desktop for usability. //Last update: May 16, 2008//

  * Target client{{ :soc:2008:mdeck:target.jpg}}
    * A few PC parts on my desk: 2.8 GHz P4 / 512 MiB RAM
    * Awaiting a PCI NIC for development
  * Desktop for usability
    * Custom desktop PC: 2.4 GHz Core2 / 2 GiB RAM
    * Windows XP Pro x64
    * [[http://www.chiark.greenend.org.uk/~sgtatham/putty/|putty]] 0.60
    * [[http://www.crimsoneditor.com/|Crimson Editor]] w/ samba file access & [[http://the.earth.li/~sgtatham/putty/0.60/htmldoc/Chapter7.html#plink|plink]] script for remote building (hello, my name is Mike and I am a Windows addict) <code>plink -l USER -batch -m commands.txt 192.168.2.1</code>
    * Windows Media Player for tunes ;)
  * Development server{{ :soc:2008:mdeck:server.jpg}}
