Bios Mods -The Best BIOS Update and Modification Source

HP Envy X360 M6-AR004DX

BIOS Link: http://ftp.hp.com/pub/softpaq/sp78501-79000/sp78586.exe

Current BIOS menu does not show Advanced menu. I would like as much unlocked as possible, but main concern is ability to adjust memory allocated for graphics card.
If it would be easier, are there instructions one can follow for unlocking newer Insyde bios manually? Those i have found seem to be in reference to older versions that use fd files rather than bin files.

Thank you in advance!

Sorry to necro but I've also got this machine and would like an unlocked BIOS!

My main request(s) for the BIOS unlock:
- Ability to manually set dedicated VRAM amount, up to 2 GB.
- Ability to switch RAM into single channel mode (This laptop has only 1 DIMM slot, however the HP was lazy and left the BIOS configured for dual channel. Will post a quote from someone more knowledgeable than me as to why this is important!)

"Furthermore, HP opted to [censored] up even more by not configuring the BIOS to operate that single channel to it's maximum potential. It is left setup in Dual-Channel mode and running at 64bit per channel, versus the 128bit it's capable of in Single Channel operation."
