HP ProBook 6460b full Windows support
So I have an HP ProBook 6460b and I can already run Linux perfectly with coreboot. I originally installed coreboot because I wanted to be able to run an i7-3840qm, along with circumventing the WiFi card whitelist (currently I have a BE200 installed too).
To use coreboot, which has no preset for the 6460b, I selected the EliteBook 8460p under the assumption that the two systems are close enough.
Obviously, I know it's frowned upon to run Windows with coreboot, and I already have got it almost totally working with SeaBIOS. I used the option rom v2170 instead of libgfxinit, and even ripped an ME 8 blob from a ProBook 6470b BIOS, which surprisingly still POSTed.
Anyway, the main issue I'm having currently is that in Windows 10, the battery icon reports that there are no batteries physically installed. This is not the case in Linux; it has no trouble reading the battery meter. I want to at least have the ability to run Windows 7, hence my choice of SeaBIOS, and currently the installer does not boot (it gets stuck on the glowy logo). In Windows 10, I have yet to get power management working correctly either; the system gets stuck when attempting to shutdown, sleep, or reboot, and nothing happens.
What do I need to do to fix my install to finally get it working fully?
