Issues
- TPM. At the moment there is only basic support inside coreboot...
- Boot time issues ( keyboard rest timeout )
- ultrabay hot plug (event missing?)
- some power management states missing
Nvidia GPU
State of dual graphics on Lenovo Notebooks: Board:lenovo/Nvidia_Optimus
Tested OS
- Linux (through SeaBIOS-as-payload and GRUB-as-payload)
- Windows (version>=7, through SeaBIOS as payload with proprietary VGA BIOS)
Proprietary Components Status
- CPU Microcode
- FDT(Flash Descriptor Table) => Always needed
- ME(Management Engine) => you do not have to touch it(just leave it where it is)
- GbE(Gigabit Ethernet embedded mac) => you do not have to touch it(just leave it where it is)
Building Firmware
Please have a look at Intel_Sandybridge_Build_Tutorial.
Flashing
T520 has a ST / numonyx M25PX64VG 8 MiB flash chip in a VDFPN8 package or a Winbond W25Q64.V 8MiB flash chip in a SOIC-8 package.
All Battery's and the Power-supply must be disconnected before flashing.
Next to the flash chip is a connector solder place "J100" where it is connected to.
-------- side to the screen -------- NC VCC HOLD CLK MOSI NC CS MISO WP GND -------- side to the palm rest --------
We can see that the connector is very similar to an SOIC-8 flash pinout.
VCC -- 8 --+-+-- 1 -- CS HOLD -- 7 --+ +-- 2 -- MISO CLK -- 6 --+ +-- 3 -- WP MOSI -- 5 --+-+-- 4 -- GND
Here are two picture showing the J100 solder place and a connector soldered to it.
Flash layout: FLREG0: 0x00000000
Flash Region 0 (Flash Descriptor): 00000000 - 00000fff
FLREG1: 0x07ff0500
Flash Region 1 (BIOS): 00500000 - 007fffff
FLREG2: 0x04ff0003
Flash Region 2 (Intel ME): 00003000 - 004fffff
FLREG3: 0x00020001
Flash Region 3 (GbE): 00001000 - 00002fff
FLREG4: 0x00000fff
Flash Region 4 (Platform Data): 00fff000 - 00000fff (unused)
Vendor firmware locks the flash and so you need to flash externally (unless until someone figures out a way around it).
