  - 經由RAM安裝ipkg-opt後, 打包, 壓縮.
  - 外接式硬碟已事先分割, 格式化.
  - 將硬碟磁區掛載於/opt

== 借用RAM, 掛載/jffs, /opt ==
<code>
# mkdir /tmp/jffs
# mount /tmp/jffs /jffs -o bind
# mkdir -p /jffs/tmp/ipkg
# mkdir /jffs/opt
# mount /jffs/opt /opt -o bind
# mkdir /opt/etc
</code>
== 設定Optware資料來源 ==
# cat > /opt/etc/ipkg.conf
<code>
src optware http://ipkg.nslu2-linux.org/feeds/optware/ddwrt/cross/stable
dest root /jffs
</code>
ctrl-d 結束.
== 更改ipkg設定檔路徑 ==
<code>
# export IPKG_CONF_DIR=/opt/etc
</code>
== 更新資料來源 ==
<code>
# ipkg update
</code>
== 安裝ipkg-opt ==
<code>
# ipkg -force-depends install ipkg-opt
</code>
輸入Y, 覆寫原有設定檔.
== 再更新資料來源 ==
<code>
# ipkg-opt update
</code>
== 再安裝ipkg-opt ==
<code>
# ipkg-opt install ipkg-opt
</code>
== 檢查已安裝套件 ==
# ipkg-opt list_installed
<code>
ipkg-opt - 0.99.163-10 - The Itsy Package Manager
uclibc-opt - 0.9.28-13 - micro C library for embedded Linux systems
Successfully terminated.
</code>
== 打包, 壓縮 ==
<code>
# cd /opt
# tar -cvf /tmp/dd-wrt_optware.tar *
# gzip /tmp/dd-wrt_optware.tar
</code>
== 上傳到FTP server ==
ftpput [options] remote-host remote-file local-file
<code>
# ftpput -u username -p password 192.168.1.250 dd-wrt_optware.tar /tmp/dd-wrt_optware.tar
</code>
== 恢復出廠預設值, 關閉電源 ==
{{http://digiland.tw/uploads/614_dd-wrt_factory_defaults.gif}}
== 安裝已格式化硬碟, 開啟電源 ==
  - 設定PPPoE, 時區, NTP server等.
  - 驅動USB, ext2/ext3, 掛載/opt
  - 重新啟動路由器.

== 下載dd-wrt_optware.tar.gz到/tmp ==
ftpget [options] remote-host local-file remote-file
<code>
# ftpget -u username -p password 192.168.1.250 /tmp/dd-wrt_optware.tar.gz dd-wrt_optware.tar.gz
</code>
== 解壓縮到/opt ==
<code>
# tar -xzvf /tmp/dd-wrt_optware.tar.gz -C /opt
</code>
== 更新套件來源與已安裝套件 ==
<code>
# ipkg-opt update
# ipkg-opt upgrade
</code>
== 重新啟動路由器 ==
