Bios Mods -The Best BIOS Update and Modification Source

Hi guys,

I've recently bought a HP 250 G4 (Model: T6P47EA#ABU) and was wondering if someone could possibly unlock the BIOS for it, so I could access all menus and options?

It's an InsydeH20 Rev. 5.0 BIOS.

Bios file from HP (I assume this is the correct one?): http://ftp.hp.com/pub/softpaq/sp74501-75000/sp74599.exe

Screenshots of current menu items:

Anyone able to kindly do this?

Thanks,
Chris
