Greetings, this laptop features 2 full size M2 2280 slots and the i7-1165G7, so plenty of PCIE lanes, but for some reason this BIOS has the second PCIE M2 slot limited to PCIE 3x2 (instead of PCIE 3x4). Hopefully, and advanced unlocked BIOS will unlock PCIE 3x4 on this secondary M2 slot.

Hi, i'm interested in having access to the advanced menu entries in bios.

You can get the bios version 2.00 (FNCNWW30) here:

Can't upload it due to its size.

Thanks

Hi
How did you get this file?

It's the bin file inside Lenovo official bios upgrade tool.

Hi!

Just for anyone trying to access the bios debug menu. I've successfully entered to it following this:

1- Power Up and enter BIOS (F1)
2- Press OK at the message
3- Press Power Button to shut it down
4- Holding Fn Key press:
a. F1 -> 1 -> q -> a -> z
b. F2 -> 2 -> w -> s -> x
c. F3 -> 3 -> e -> d -> c
d. F4 -> 4 -> r -> f -> v
e. F5 -> 5 -> t -> g -> b
f. F6 -> 6 -> y -> h -> n
5- Release Fn Key
6- Power Up and enter BIOS.

You should now see the Bios Debug Menu.

Be carefull, a wrong change could lead you to a softbrick.

It's work on thinkbook 14 g2 are, but i change ram frequency and have black screen, maybe softbricked. Unplug battery and cmos battery, for 6 hours, but stay black screen.
