解釋: 這一行對配置網絡,連通Target Server及下載調試程序非常重要
DEFAULT_BOOT_LINE 的原意是為沒有NVRAM的target設計的,這樣用戶就不需要在每次系統啟動是手工輸入這些參數了.
系統啟動網絡時xxxEndLoad()會解釋這一行并按這一行的定義進行加載.
Emac(0,0) : 啟動設備,可是是軟盤,硬盤,PCMCIA卡等 其他的設備名稱如:
fd為軟盤,(0,0)表示個軟驅,3.5寸盤.
dc則表示從DEC 21x4x 芯片啟動,即系統有NVRAM存在,這種方式現在已不采用.
elpci表示啟動設備為3COM EtherLink XL PCI網卡.

Tornado for x86下BSP的生成,下載和Target Server的配置實例，Pentium主機，3Com網卡，軟盤引導，ftp下載VxWorks映像。
1.在C:\Tornado\target\config\pcPentium目錄下修改BSP文件config.h。
#elif (CPU_VARIANT == PENTIUM)
#define DEFAULT_BOOT_LINE
"elt(0,0)HOST:c:\\Tornado\\target\\config\\pcPentium\\vxWorks
h=90.0.0.3 e=90.0.0.50 u=target pw=target tn=target"
#define INCLUDE_ELT //3Com網卡
#define INCLUDE_END //END驅動
2.打開Tornado選擇新建一個bootable vxworks image，選擇建 A BSP，選擇pcPentium，建完后編譯就可以在相應的目錄下生成vxworks的映像文件。
3.制作bootrom；選擇Build Boot Rom，選擇pcPentium,再選擇bootrom_uncmp，生成 bootrom_uncmp。拷貝 bootrom_uncmp到host\x86-win32\bin下，插入空白盤到軟區，在dos界面進入目錄host\x86-win32\bin下，用命令"mkboot a: bootrom_uncmp "生成引導盤
4. 在Start > Programs > Tornado2 > FTP Server，點開Security下的user/rights菜單，新建用戶User Name:target，Password:target，Home Directory為VxWorks映像所在目錄如 C:\Tornado\target\config\pcPentium\。注意這些配置要和config.h中的一致。
5.將bootrom的啟動盤插入目標機的軟驅，啟動目標機，系統從軟驅啟動，隨后登陸FTP，從主機下載vxworks文件，目標機提示7秒內按任意鍵選擇Boot方式（手工，自動），手工方式可對FTP用戶，口令，IP等參數進行修改。通常是等待7秒后系統autoboot。
屏幕顯示：
Attached TCP/IP interface to elt0.
Attaching network interface lo0... done. //TCP/IP網絡連接成功
Loading... 602128 //通過ftp下載VxWorks映像
Starting at 0x01080000 //下載成功，從RAM_LOW_ADRS 0x01080000
開始執行VxWorks系統
Attached TCP/IP interface to elt unit 0
Attaching interface lo0...done //TCP/IP網絡連接成功
(注意這里網絡初始化成功和上邊的不同，上邊是Bootrom映像網絡初始化來下載VxWorks,這里VxWorks系統初始化網絡。)

至此目標機系統啟動完成。
6.配置Target Server下載應用程序.
打開Tornado，在Tools菜單下選擇Target Sever再選擇configure進行配置(Tools > Target Server > Configure > New)給出Target Server名字描述如net00.在(Target Server Properties > Back End)選擇WdbRpc. Target Name/IP Address
框內輸入Target的IP: 90.0.0.50. Core File and Symbols選項(Target Server Properties > Core File and Symbols)： C:\Tornado\target\config\pcPentium\vxWorks等等。配置的內容根據系統的具體情況定。點擊Launch啟動Target Sever，隨后在主界面下選擇已啟動的Target Sever就可以下載 *.o或*.out程序。
