之前網路上找不到 NSC1000 的直接相關的改機資訊。
Why? Why? Why?

cross-*.tar.bz2 和 cross-*.tgz 是相同的內容, 浪費了 200MB 的空間。
NSC1000 和 WLNSC1000 的 source code 是通用的，不過裡面只有主程式，
缺少各個資料檔案，雖然能夠做出 upgrade.bin，不建議自行升級 firmware。

hexdump -C upgrade.img => MGB111

從 readme 可以推測，是 amit ODM 的產品，Linux 2.4.28

The firmware file usually contains several parts:
    * Linux kernel
    * Ramdisk containing root file system
    * Partition with HTML files
    * Recovery loader
    * AMIT BIOS

The memorymap in the FLASH (located at 0xFFC00000):
00000010 Linux Kernel
00100010 root fs
003a0010 config
003b0010 filesystem of admin tool
003f0010 System recovery tool
003f8010 MAC-address and branding
003fa010 BIOS 

The GUI filesystem
The proprietary http binary takes the pages from a seperate uncompressed filesystem 
(direct access or via proprietary libraries, not mounted). Unfortunately, I didn’t have time to 
investigate further in this matter. There would be a lot of necessary changes to the html and script code. 
I think it can’t be too sophisticated (coming from the AMIT company). Maybe it is only some simple fs 
with modified “magic” (@M!T → AMIT). It has some sort of table, followed by a directory and the data. 
dir entries are 24byte, filename is 8.3, limited with 0&times;00. Padding/Filler byte seems to be 0xff.
