解释: 这一行对配置网络,连通Target Server及下载调试程序非常重要
DEFAULT_BOOT_LINE 的原意是为没有NVRAM的target设计的,这样用户就不需要在每次系统启动是手工输入这些参数了.
系统启动网络时xxxEndLoad()会解释这一行并按这一行的定义进行加载.
Emac(0,0) : 启动设备,可是是软盘,硬盘,PCMCIA卡等 其他的设备名称如:
fd为软盘,(0,0)表示第一个软驱,3.5寸盘.
dc则表示从DEC 21x4x 芯片启动,即系统有NVRAM存在,这种方式现在已不采用.
elpci表示启动设备为3COM EtherLink XL PCI网卡.
fei:Intel 82559 EtherExpress网卡.
ene: NE2000网卡
ELT: 3COM以太网卡
EEX: Intel网卡
ata: ATA/IDE 硬盘 ............
