I have looked around a bit at the firmwares for the ovislink router great specs:
ovislink_os_1.01.043 (without wireless support)
ovislink_os_1.01.044w

This is what I have so far:
0x00000000 - Start of the MBR master boot record
MIPS 4km code probably with decompression / (decryption?) part.
0x00003b08 - Start of the compressed kernel image
0x00100000 - Start of some UNKNOWN binary image
compressed / encrypted?? rom?? image
end-40 - Start of a MD5 checksum??

We need a way to work out how get at this UNKNOWN binary image.
I believe this is some sort of compressed filesystem that holds the key to customising the box.

Anyone open for suggestions?
- Could try the mips42emul, which is able to boot a similar linksys and netgear devices...

Heres some code I used to extract the images:
head -c 14552 ovislink_os_1.01.044w > mbr.bin
tail -c 6860632 ovislink_os_1.01.044w | gzip -dc > image.bin
tail -c 5826608 ovislink_os_1.01.044w > unknown.bin

head -c 14552 ovislink_os_1.01.043 > mbr2.bin
tail -c 5776216 ovislink_os_1.01.043 | gzip -dc > image2.bin
tail -c 4742192 ovislink_os_1.01.043 > unknown2.bin

Hopefully we can crack this nut, otherwise I have to wait for the 500gx...

Best regards,

This topic is moved from wl500gx specs - it does not have anything common with wl500gx, as well as this forum completely.
Do you FCC ID for this product or internal pictures?

Well Antiloop has to decide whether or not he will start forums for other brands/types of routers as well. There are so may of them and knowing him to be a Asus fan; I doubt it.

That doesn't mean the Ovislink isn't interesting, but I think going at it will delute the resources we have here...

I understand, this is an ASUS forum only. I just hoped to profit from the very good concentration of brainpower...;

Is there a posibillity to have a "other hardware Q&A" thread on the site?

Is there a posibillity to have a "other hardware Q&A" thread on the site? That depends on Antiloop, as he is the forum owner. He is currently AFK for another week. After that there will be a decision made in conjunction with (hopefully) Oleg', Technik', mine and perhaps the community's ideas.

You'll have to wait for that...
