Thanks for your interest in HP Elitebook 2760p port.

Status

Intel_Native_Raminit has it's own status page.

Tested and working:

RAM module combinations of 0+8G, 4G+8G
USB
Video (internal)
WLAN
Linux (through SeaBIOS as payload)
Keyboard, trackpoint, touchpad
Fan control
Expresscard
AC and battery status

Not working:

GRUB payload will freeze
digitizer

Not tested:

VGA
Sound (integrated speakers, integrated mic, external headphones, external mic)
LAN
WWAN
SD card slot
Fingerprint reader
Webcam
Thermal management
bluetooth
dock
msata
fn hotkeys

proprietary components status

CPU Microcode
VGA Option ROM (optional)
ME (Management Engine) firmware
EC (Embedded Controller): The EC in this laptop is SMSC KBC1126. It needs two blobs in the flash chip.

Building

See HP Elitebook for instructions of building coreboot for HP Elitebooks.

Flashing

The flash chip of this laptop is socketed beside the WLAN slot. You can flash the firmware to another chip and replace it. The original flash chip is MX25L6445E.

You can also do an internal flashing with flashrom after you have coreboot installed and IFD unlocked.

-* EC (Embedded Controller): The EC in this laptop is SMSC KBC1126. It needs two blobs in the flash chip. You can move the blob from 0x780000 to another address in the flash chip so that you can have a bigger CBFS size. Read [https://github.com/mytbk/firmware_notes/blob/master/blobs_for_hp_laptops.rst this post] for more info.

-The source code is at https://review.coreboot.org/#/c/18241/. You can check it out and rebase it on the master branch.
+See [[HP Elitebook]] for instructions of building coreboot for HP Elitebooks.
-Extract the blobs needed by EC according to [https://github.com/mytbk/firmware_notes/blob/master/machines/2760p/2760p-coreboot.rst#how-to-build-it this post] and use dd to write it to coreboot.rom.
