+== ITRI SSTC & DRBL ==
+
+ * 問題一：Ubuntu 10.04, 10.10, 11.04 都沒有 [http://packages.ubuntu.com/search?keywords=partimage&searchon=names&suite=all&section=all partimage 的 amd64 版本]
+{{{

+    * dapper (admin): backup partitions into a compressed image file [universe]
+      0.6.4-14: amd64 i386 powerpc
+    * hardy (admin): backup partitions into a compressed image file [universe]

+    * oneiric (admin): backup partitions into a compressed image file [universe]
+      0.6.8-2build1: amd64 i386
+}}}
+ * 問題二: 網卡不被支援 - Debian GNU/Linux 6.0.2 (squeeze) 不行，Ubuntu 要 10.10 以後版本的預設核心才行。
+{{{
+00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04)
+00:19.0 0200: 8086:1502 (rev 04)
+}}}
+  * 2.6.32-5-amd64 的 e1000e 不支援這個 pciid，所以改裝 3.0.0-1-amd64
+{{{

+}}}
+ * 問題三：改裝 3.0.0-1-amd64 會有另外的問題，就是 initrd-pxe.3.0.0-1-amd64.img 無法正常載入 e1000e 的模組，會出現
+{{{
+"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+"The driver of network card is NOT found!"
+"Is this kernel $kernel_ver too old so it does not support this network card ?"
+"Without network card driver, we can NOT go on!"
+"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+"Now enter shell to debug..."
+}}}
+ * 但是在 shell 中不做任何動作，直接下 exit 之後，又可以正常網路開機。因此懷疑 3.0.0-1-amd64 的開機速度較快，或 modprobe 程序有誤。
+ * <解法> 目前暫時修改 /usr/lib/mkpxeinitrd-net/initrd-skel/bin/insert-modules 加入 sleep 1 的描述，則可以順利開機。
