Hello,
I have had partial success with flashing my T60. After the first flash the laptop re-booted OK, but the screen is completely black. Fiddling with the backlight buttons doesn't have any effect. Fortunately, I can connect via ssh so I am not locked out.
I believe that my mistake was to put my ATI VGA bios into coreboot rather than SeaBIOS. I have now corrected this but I can't flash the updated version. For the first flash I used the following command:
./flashrom/i686/flashrom_lenovobios_sst -p internal -w coreboot.rom
I got loads of errors as mentioned in the instructions, but it seemed to work. Since I now want to do another flash I have followed the instructions and used this simpler command:
./flashrom/i686/flashrom -p internal -w coreboot.rom
I get the following error:
flashrom v0.9.8-unknown on Linux 3.10.0-229.4.2.el7.x86_64 (x86_64) flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK. coreboot table found at 0xbfea0000. ======================================================================== WARNING! You seem to be running flashrom on an unsupported laptop. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and http://www.flashrom.org/Laptops for details.
If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== Aborting. Error: Programmer initialization failed.
I have tried flashrom, flashrom_lenovobios_sst and flashrom_lenovobios_macronix and get the same error every time. I have also tried re-flashing the current working but blank screen bios and that won't go in either.
Suggestions gratefully received.
