网络环境：局域网一台跑vmware的2K3主机，上端有路由器通过ADSL方式联入INTERNET。
从官网http://downloads.openwrt.org/snapshots/trunk/x86/openwrt-x86-generic-combined-ext4.img.gz
下载固件到硬盘。
解压，虚拟机光驱加载winpe，用physdiskwrite将固件写入到虚拟机磁盘上。
写入完毕关机，在虚拟机设置中将光驱移除，开机。
进入系统后设置网络接口，将eth1设置为wan口：
vi /cd etc/config/network
config 'interface' 'wan'
        option 'ifname' 'eth1'
        option 'proto' 'dhcp'
        option 'defaultroute' '1'
        option 'peerdns' '0'
        option 'dns' '8.8.8.8'
关虚拟机，在虚拟机设置中将eth1对应的网卡桥接在物理网卡1上(此网卡连局域网路由器），重启openwrt。
然后在局域网路由器里面可以给openwrt的wan口分到IP地址，此时openwrt可以访问网络。
然后继续安装luci
opkg update
opkg intsall luci
安装完毕启动luci
/etc/init.d/uhttpd enable
/etc/init.d/uhttpd start
由于openwrt里面防火墙的默认设置，无法直接通过wan口访问luci界面，先关掉防火墙：

/etc/init.d/firewall stop
此时可以通过web访问luci界面，但是密码未设置，此时是不能登入luci的。

telnet到路由器，passwd设置密码，完成后登录luci界面。

发现 Belkin F7D4302v1 的CPU和610n v2一样都是 CPU type 0x19740，而610n v2频率为480Mhz，试图超频F7D4302v1。
