= 瞭解 Etherboot 如何加入新的網路卡驅動程式 =
== STEP 1: 從 Etherboot 原始碼開始 ==
 * 源起:
   * 目前有很多新的網路卡雖然有支援 PXE 但是卻沒有正式被 PXELinux 支援. 所以必須要找到可以自行加入新網路卡的方法.
 * 作法:
   * 測試環境: Debian Etch 4.0r1
   * 下載 git 版本控制軟體
{{{
# apt-get install git cogito git-core
}}}
   * 修改 git 預設對應
{{{
# update-alternative --config git
There are 2 alternatives which provide `git'.

  Selection    Alternative
-----------------------------------------------
 +        1    /usr/bin/git.transition
*         2    /usr/bin/git-scm

Press enter to keep the default[*], or type selection number: 2
}}}
   * 如果不修改預設 git 對應為 git-scm 會出現以下錯誤訊息
{{{
# git clone git://git.etherboot.org/scm/gpxe.git

git, the filemanager with GNU Interactive Tools, is now called gitfm.

If you are looking for git, Linus Torvald's content tracker, install
the cogito and git-core packages and see README.Debian and git(7).

This transition script will be removed in the debian stable
release after etch.

If you wish to complete the transition early, install git-core
and use (as root):
 update-alternatives --config git

Press RETURN to run gitfm

   * 下載 Etherboot 最新版原始碼
{{{
# git clone git://git.etherboot.org/scm/gpxe.git
}}}
   * 從 Etherboot 原始碼中的 src/drivers/net/sis900.c 開始看
{{{
# cd gpxe
~/gpxe# cd src/drivers/net/
~/gpxe/src/drivers/net/# ls sis900*
