Excellent to see this. My X230 should arrive next week and I will give this a try. I haven't flashed a BIOS like this before so every high-quality write-up like this helps me understand some things to watch out for.

AFAIK, almost the same process is used for Bios whitelisting. Meaning, Lenovo(and I guess others) has hardwired in the bios that only secific vendors+versions off e.g. WIFI cards can be used. You would dump the bios, same as described in the article, do some magic, and write it the altered bios back. If anybody can enlighten me on the magic part, I would be very thankful.

Notice any problems with the RTC? Mine doesn't work on a T420 after flashing. The clock jumps ahead 50 years every time I power off.

No RTC problems seen here.

I fixed it by setting the system time (so that "date" returned the correct time), then I ran "sudo hwclock --systohc".
