BIOS whitelist mod for version 1.46 W520 ThinkPad?

#1 Post by webangel » Sun Sep 25, 2022 9:51 pm

Hey gang, I'm really new to some of this more complicated stuff but I ended up getting my hands on a W520 ThinkPad the other day. After trying to improve the bluetooth funcitonality by upgrading my BIOS, I decided I would just buy a new wifi chip altogether. Now I regret upgrading the BIOS previously because I can't find any download links anywhere for the whitelist mod. Again, I'm on version 1.46 of the BIOS.

Does anyone know where I could track this down or have it sent to me? I would really greatly appreciate any help.

Hi,
For whatever reason (SEO/indexing I guess), this is very hard to find. Seemingly the only valid link anywhere on an English-language website that is indexed is right here on this very same site.

Refer to this thread/reply: https://www.thinkpads.com/forum/viewtop ... 38#p840338
Since it has been edited literally years after it was first posted, it looks like Shredder11 is conscientious about how hard these files are to find.

The 1.46, no whitelist, RAM speed unlocked BIOS is what has been on my W520 for about the past year, running a 7260-AC and 1600MHz RAM successfully.

Note this is not the version that unlocks the advanced settings menu, which I've only heard of and never seen. That version seems to be completely lost to time until someone else figures out how to re-mod it again.

Have you had any stability or slow-down issues? As I recall, a user on Reddit complained that after they applied the whitelist+RAM_UL v1.46 BIOS on their W520 they had system slow-downs and stability issues not related to OC'd RAM.

Any chance you've come across the v1.46 with only the whitelist removed?

BTW, my reason for the modded BIOS is that I want to upgrade my WiFi to an AX200 card.

Cheers!

I just did a quick search and not many results came up, but this one was on there and the forum topic (four years ago) had someone who ended up paying money to get the BIOS, and is offering to share it if others will also share the original $30 cost to him. https://www.reddit.com/r/Lenovo/comment ... s_ver_146/

Another possibility could be to contact this guy Stefan Schmidt, who modded his own Thinkpad T440p BIOS to remove the Whitelist. Who knows maybe he will do it for you. http://thrimbor.github.io/2019/09/24/re ... t440p.html

Thanks for the info. However, it turns out that I'm getting old, and my memory is going. I forgot that when I first got the W520 used back in 2014, I had replaced its ThinkPad 1x1 b/g/n Wireless LAN Mini-PCI Express Adapter II with an Intel 7260AC. Thus I already have a BIOS with the whitelist removed. I somehow managed to misplace the BIOS, which is surprising as I'm pretty anal about keeping such things; I've got stuff on my server dating back to my first personal ThinkPad back in 2007.

Now, if I knew how to suck the BIOS out of my machine without having to buy one of those USB EEPROM readers, I could post it.
