Revision as of 08:36, 20 July 2017

Thanks for your interest in HP Elitebook 2760p port. This port is a work in progress.

Status

Intel_Native_Raminit has it's own status page.

Tested and working:

S3 (Suspend to RAM)
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

The source code is at https://review.coreboot.org/#/c/18241/. You can check it out and rebase it on the master branch.

First, you need to extract the blobs needed by EC firmware using util/kbc1126. You can extract them from your backup firmware image, or firmware update provided by HP as follows:

 wget https://ftp.hp.com/pub/softpaq/sp79501-80000/sp79710.exe
 unar sp79710.exe
 ${COREBOOT_DIR}/util/kbc1126/kbc1126_ec_dump sp79710/Rompaq/68SOU.BIN
 mv 68SOU.BIN.fw1 ${COREBOOT_DIR}/2760p-fw1.bin
 mv 68SOU.BIN.fw2 ${COREBOOT_DIR}/2760p-fw2.bin

When you config coreboot, select:

 Chipset --->
   [*] Add firmware images for KBC1126 EC
       (2760p-fw1.bin) KBC1126 firmware #1 path and filename
       (2760p-fw2.bin) KBC1126 filename #2 path and filename

Then just make your firmware.

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.

You can move the blob from 0x780000 to another address in the flash chip so that you can have a bigger CBFS size.
