Greetings, currently i'm trying to boot my laptop over the newly flashed bios with coreboot, but actually, despite power button, leds and cd player working properly i dont get any response from the display.
Hardware properties: Model: Lenovo/IBM T60p 8742 Y19 CPU: Intel Core 2 Duo T7200 AVG Controller: ATI 71d4 (PCI) GPU: Mobility FireGL V5250 MB-Chipset: Mobile 945GM/PM/GMS940 GML and 945GT Express Southbridge: ICH7-M SuperI/O: Renesas H8S2161B (not confirmed) Socket: 479
BIOS chip: SST 25vf0168 50-4c-s2 af 0707084-A (16Mbit)
Installation History: 1) Image Build: builded on the native laptop through Gentoo installed on USB, from an amd64 (march=native) version: Options chosen other than default: - Lenovo T60 (p) - Dont save config options - Dont compress SeaBios - Stable Seabios Version - mmx,smp,sse,sse2 - chip size: 2048Kb [coreboot.rom image attached]
2) Flash ROM: - built an DLP Design DLP-USB1232H ( http://flashrom.org/FT2232SPI_Programmer#DLP_Design_DLP-USB1232H ) - disassembled Chip from MB and placed it in a SOIC8 socket - assembled needed jump wires on the socket pins / placed it in the 1232H circuit - from another laptop with another gentoo amd64 (march=native): installed Flashrom - flashrom -p ft2232_spi:type=2232H,port=A -w coreboot.rom [flash log attached]
3) Original Setup: - chip re-assembled on the MB - Laptop re-assembled
Could i do any further check to get the problem? if needed i can give further informations (eg output files from the build directory)
Thanks for the attention, Matias Jose' Seco

Was your gcc and binutils built with USE=vanilla? If not, it is completely possible that your toolchain produced a broken image. I've had this happen with some gcc versions.
Options chosen other than default:
- Lenovo T60 (p)
- Dont save config options
CMOS/NVRAM? That may need to be enabled for image to work.
- mmx,smp,sse,sse2
How did you set this exactly?

Get a docking station, port replicator or ultrabay superio module, so that you get a serial port, and connect that to another computer. coreboot should output debug information there when starting, and it may be clear what the problem is.
Also, does it seem like the system boots? Is there some hard drive access after you power on?
And, does caps lock work after you power on?
Finally, did you include a VGA BIOS into your coreboot.rom? This is easiest done by configuring the filename in menuconfig. Note that coreboot should not execute the VGA BIOS, the file should only be added. You may need to change the defaults for this.

you can download the coreboot Image i'm running on my T60p from http://stackframe.org/coreboot_t60p.rom, which should also run on your system.
Did you extract and add a VGA BIOS image? Note that you have to capture the vgabios during runtime from Linux, because the Lenovo BIOS does some Table patching at boot to enable the LVDS (=TFT) Display port.
You might also extract the VGA BIOS image from my coreboot.rom file:
cbfstool coreboot_t60p.rom extract pci1003,71c4.rom vgabios.rom
