- Usual limitations apply for native graphics initialization
- (no VBT and/or INT10H and only GRUB works so no BIOS, so no DOS/Windows support
- - who cares? There is no system but GNU, and Linux is one of it's kernels).

- <p>
- When connecting the AC adapter while system is powered off, system will then power on.
- This probably happens in coreboot aswell (with or without blobs).
- It's a minor annoyance, but it should be fixed (if it's not already fixed by now).

- This method of disabling the ME leaves the flash descriptor and gbe in place (non-functional data, fully documented)
- and disables the ME using soft straps. This means that the gigabit ethernet will still work (putting the system in
- non-descriptor mode would wipe it out).
