Takahashi Posted February 22, 2015 Share Posted February 22, 2015 Hello OSXLatitude. Lenovo has implemented a PCI device whitelist into the BIOS of Lenovo G505s (20255). This disables me from using wireless cards other than those authorized by Lenovo. I purchased a Broadcom BCM943225HMB (Hackintosh-compatible) from Amazon, and upon installing it, I sadly found out then and there. I have linked the latest BIOS update (v3.00) along with its readme for use if necessary. https://www.dropbox.com/sh/j6d5w032axhk4f5/AADM3EN2jON7N4Cb8tZQyVeya?dl=0 1 Quote Link to comment Share on other sites More sharing options...

SonyBoy2 Posted October 9, 2015 Share Posted October 9, 2015 Dear friends! Dont worry, I have a perfect solution for your problem! You could just get a Coreboot open source BIOS (which supports Lenovo G505S) and flash it to your laptop! More information, how to get this wonderful BIOS and flash it, could be found here:https://www.bios-mods.com/forum/Thread-REQUEST-Lenovo-G505s-bios-unlock-advance-options?pid=100299#pid100299Because it is open source, you can modify the source as much as you want, everything is unlocked, and there are no WiFi whitelists or other stupid restrictions! BTW Atheros WiFi cards, such as AR9462 or AR9485, would have been much better than Broadcom. These Atheros cards work very good, cost cheap, very stable WiFi, and they work perfectly under Linux without needing any proprietary firmware drivers P.S. You will need to spend some money on a flashing hardware, could get for under $10 from China... Quote Link to comment Share on other sites More sharing options...
