With the M910q you shouldn't have to copy and paste a BIOS as the M910q already supports Kaby Lake (the only reason for copy/pasting as M900 doesn't support Kaby Lake)
You should just be be able to get a backup of your M910q BIOS (16MB) then run CoffeeTime over it, then copy the result back to EEPROM
So, a bit has happened. My M700 is now sitting with it's G4400T doing essential business. I just couldn't stop, though, and I now have an M910q originally shipped with an i5-7500t. I backed up my bios, and concatenated the bios update from Lenovo's site into the last half of my backup. Ran coffeetime, and got the same issue described above with the 8100T. I downgraded the ME version to 220.127.116.118, and now the fan spins but no POST. Hmmmmm.
Check again, it becomes available after registration.
You can use any new driver with a mod as long as NVIDIA supports a lousy GT710 desktop, which has an eighth of the strength of your GPU.
Actually we already have here two other 880M owners, who use these mods.
