[Request] Lenovo Yoga 900 BIOS Unlock / AHCI enable (attached BIOS fd)
#21
Do you think this bios will boot if flashed directly?

Yes, it is.I already have successful mod for Acer with Broadwell platform.User used programmer to flash directly modded image, after that laptop works good.

Please,do not post requests me in PM.Bios modding is very dangerous work.If i provide you confirmed modded bios, please donate for my dangerous work https://goo.gl/98BgtO.Thank you!

I will work on re-soldering to my chip in order to flash. Do you have any advice on bypassing the HOLD lock? Will the programming software handle this or do I need to short the pin myself?

You may try use programmer+pomona SOIC8 clip, no de-solding process needed.
However,we can try to detect what is bios chip installed on Mobo, after that you may ask seller if his hardware supports your device.
Run this tool as admin and upload results

This tool not works on win10 shell.
New bioses have double protection, first protection located in bios setup, second protection-in Descriptor region of bios image.We can get access to this region using programmer only.

The chip itself is too small to be clipped, I've already experimented extensively on it. Thankfully, the mobo itself has pads that extend past the edges of the chip that I am able to solder to.
In order to get this to work we are going to need to bypass the second check. Flashing the bios through the patched insyde utility results in a firmware check error.

first, you need flash modded image using programmer with:
-patched Descriptor region
-unlocked tabs, now you can switch off bios lock.
after that you can flash new mod using Intel FPT (for example, you need disabled whitelist check for wlan adapters)

Does your mod have a patched descriptor region?

desc region cannot be read by Intel FPT, only programmer

So you would like me to dump with my flash programmer so that you can patch the Descriptor region, and then I will be able to flash my chip with your mod.

Yes, after that you must have access to hidden settings and disable bios lock protection which set by bios setup.Now you not needed programmer to flash new mods until new update from official site be updated.
