It's amazing that I've got lots of people helping me to hack the firmware.
Especially Stephen has shown me lots of examples and tools to apply to the
We've successfully found that the romfs partition inside the firmware is a
zipped ext2 file system.
One of my friend who is a software enginner also helped me to examine the
codes in kernel.
We've found the following section in physmap.c indicates the romfs part in
firmware should not exceed 1,966,080 Bytes.
However Stephen and I found that the Romfs (Initrd) which has been
successfully extracted from firmware is about
2,939,222 bytes long. After uncompressing the Initrd, it
becomes a more than 10M bytes long mountable file.
The file size is too large to be stored in the flash partition as the
configuration insides kernel codes.
According to the previous discussion in the list, I guess D-link might not
release the kernel codes corresponds to DIR-450/451.
I've told this situation to Dlink at US by their website 1 week ago, asking
them to check if they've put wrong files on ftp site. But I haven't get any
response until today.
However, I think technical disscussion in detail might not be appeared in
But if people want to discussion about the concepts,
events, or any possible action in legal-lists will need technical
information as a evidence.
So I still reply this mail to both lists.
