请教各位大神一个PXE服务器IP地址获取的问题

jie_china

menu.lst如下这么写

set /a IP1 = *0x8288 & 0xFF
set /a IP2 = *0x8289 & 0xFF
set /a IP3 = *0x8290 & 0xFF
set /a IP4 = *0x8291 & 0xFF
set serverip = %IP1%.%IP2%.%IP3%.%IP4% || set serverip=192.168.1.1


title Boot from Win2K3_PE
map --mem http://%serverip%/ISO/win2k3pe.iso (0xff)
map --hook
chainloader (0xff)
boot

如上，获取地址失败了，变量没有生效，找不到http://%serverip%/ISO/win2k3pe.iso 路径

晕，现在莫名其妙的又好了，红色部分我是一直注释掉的，看来我的RP值有问题。如下这么用没有问题

set /a IP1 = *0x8288 & 0xFF
set /a IP2 = *0x8289 & 0xFF
set /a IP3 = *0x828A & 0xFF
set /a IP4 = *0x828B & 0xFF
set serverip = %IP1%.%IP2%.%IP3%.%IP4% || set serverip=192.168.1.1
