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
