NEW BOARD: Dell Precision T1650
Very nice ivybridge board that supports ECC RAM. NOTE: I couldn't get onboard graphics working yet, but this was confirmed working with a graphics card (in my case nvidia quadra k420) booted in text mode on the SeaBIOS payload. The GRUB payload also works, when loaded from SeaBIOS. Therefore, this is a SeaBIOS-only board (as far as first payload is concerned), but you can pick GRUB from the menu. You could make it "GRUB-only" in practise by setting SeaBIOS boot order to only load GRUB, and disable the SeaBIOS menu. We refer to this as "SeaGRUB". I've made lbmk use biosutilities and uefiextract, to get at the SMSC SCH5545 Environmental Control (EC) firmware. This firmware is needed for fan control. This is automatically downloaded and extracted, from Dell UEFI firmware updates. As with other blobs such as Intel ME, this firmware is then scrubbed by the release build scripts. The blobutil "inject" script can be used to re-insert it. Of note: there is no fixed offset, but no other blobs to be inserted in CBFS either, so the offset when re-inserting on release ROMs should still be the same, and thus the ROM checksums should match, when running blobutil inject.
