I desoldered BIOS chip from motherboard using hot-air soldering station, read it using arduino pro mini board with soft from this page http://skproj.ru/programmator-spi-flash-...om=flasher , then it was modified by Dudu2002, I write it back and solder chip back to the board. Now I can use any WiFi cards. Attempt to read chip inside motherboard was unsuccessful, may be more professional programmer can do it without desoldering.
Also, there are two bios chips on mainboard, first is 25q32 (4MBytes) which I use and second chip is 25q16 (2MBytes) - may be crush bios or smth else, you need to work with 25q32 chip.

The range is very short, I can sit outside one of my fave local coffee shops less than 100ft from the router, and it doesn't even see their signal at all. It also doesn't seem to work well with Linux. I have an older non-functional ASUS laptop which I removed the WiFi card from, and I suspect it will work. The card worked quite well in the old laptop, it is Atheros-based. It fits into the Lenovo just fine, but when I try to boot it tells me that the card is unauthorized. So I did a bit of research and discovered that it wont work because Lenovo has a whitelist of approved cards, and my card isn't one of them. I also plan to buy a new internal WiFi card in the future, preferably one that supports dual-bands, but am worried that it might not work.
But anyways, Lenovo doesn't post a BIOS file for my laptop, so I had to dump it with Universal BIOS Backup Toolkit (Lenovo G700 BIOS (Dumped)). It's an Insyde-based BIOS. I'm not sure if the BIOS is encrypted with RSA, but I don't think it is.
I would very much appreciate it if someone could mod my BIOS so it doesn't check what WiFi card I'm using. I already searched the forums for my model # but couldn't find anything related to what I need. I would also be willing to consider donating a bit to the modder and/or website if this works out. And if someone could post links to flashing and recovery instructions then that would be great. I'm new to this and just found this forum today, I'm not skilled enough to do this myself.
If any new/additional info is needed then just ask and I will provide.
Thanks in advance for any help!

Hello, i would ask for help with 7ACN89WW bios. Wifi card is dead, no wifi or works like crap and im not planning to invest in one of (if im correct) 3 stupid broadcom models. I did read all pages of thread and all links are dead or "restricted" to do it by my self.
I did make backup with Universal BIOS Backup ToolKit 2.0.
