flashrom claims T60 is unsupported

[Richard Simpson]

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.

I have tried flashrom, flashrom_lenovobios_sst and

that won't go in either.

Suggestions gratefully received.

flashrom -p internal:laptop=force_I_want_a_brick -w coreboot.rom

That should work.

Then take care of bucts again.

Carl-Daniel,

Thanks.  Despite the scary nature of the command and my lack of actual
desire for a brick, that seems to have worked to get the new bios in.
Sadly the screen is still black.  I have created a separate thread to
ask about that rather different problem.

T60 with ATI has black screen

[Richard Simpson]

Hello,

I have finally successfully flashed the BIOS on my T60 with coreboot.
Sadly, my ATI controlled screen remains completely black.  Fortunately I
can still get in via ssh.  Here is what I can deduce so far.

lspci says:
01:00.0 0300: 1002:7145 (prog-if 00 [VGA controller])

<TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 0, Cache Line Size: 64 bytes
        Interrupt: pin A routed to IRQ 16
        Region 0: Memory at e0000000 (32-bit, prefetchable) [size=128M]
        Region 1: I/O ports at 4000 [size=256]
        Region 2: Memory at ec120000 (32-bit, non-prefetchable) [size=64K]
        Expansion ROM at ec100000 [disabled] [size=128K]
        Capabilities: <access denied>
        Kernel driver in use: radeon

The vgabios which I extracted from the factory bios reports as follows:

Image 1:
PCI Expansion ROM Header:
  Signature: 0x55aa (Ok)
  CPU unique data: 0x7e 0xe9 0x6f 0x02 0x00 0x00 0x00 0x00
                   0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
  Pointer to PCI Data Structure: 0x0230

PCI Data Structure:
  Signature: 0x50434952 'PCIR' (Ok)
  Vendor ID: 0x1002
  Device ID: 0x7145
  Vital Product Data:  0x0000
  PCI Data Structure Length: 0x0018 (24 bytes)
  PCI Data Structure Revision: 0x00
  Class Code: 0x030000 (VGA Display controller)
  Image Length: 0x007e blocks (64512 bytes)
  Revision Level of Code/Data: 0x090c
  Code Type: 0x00 (Intel x86)

  Reserved: 0x0000

Platform specific data for x86 compliant option rom:
  Initialization Size: 0x7e (64512 bytes)
  Entry point for INIT function: 0x275

This looks like the right VGA BIOS to me.

Once I have added it to the coreboot image I can check the contents as
follows:

coreboot.rom: 2048 kB, bootblocksize 952, romsize 2097152, offset 0x0
alignment: 64 bytes, architecture: x86

(empty)                        0x53740    null         1754264

I would be most grateful for any suggestions as to where I might be
going wring or further diagnostics.

Thanks,

AFAICS you have exactly the same T60 as I have.

Ah yes. Bad idea. AFAIK the factory BIOS patches the VGA optionrom at
runtime with the correct values for the LVDS panel. This means you
either have to patch the VGA optionrom yourself or you have to extract
the VGA optionrom from the memory of the running system. If you extract
it from memory, please note that the runtime patching causes the
checksum to be incorrect, and you either have to fix the checksum or
tell SeaBIOS to ignore the checksum.

On the first coreboot try I had a black screen as well on my T60 (ATI
graphics). Funnily enough, the external VGA worked. Could you check if
that's the case for you?

T60 with ATI has black screen

[Richard Simpson]

Carl-Daniel,

I have to say that knowing that you have the same T60 and that it is
working is a big moral boost!

Yes, the VGA port is working.

Can you possibly expand on your instructions below?

1) You suggest that I patch the option ROM myself.  Where would I find
instructions on how to do this?

2) If I decide that I need to extract it from a running system then I
presume that I need to re-flash the factory BIOS.  Can I just do this
with the same flashrom command that I used to flash coreboot?

3) On this page (http://www.coreboot.org/VGA_support) two ways of
getting the video BIOS from a running system are listed ('Retrieval via
Linux kernel' and 'Extraction from mapped memory').  Does it matter
which one I try?

4) Can you be a lot more specific about what I should do about the checksum?

Apologies if all these instructions are in the Wiki and I have been too
dumb to find them.

Regards,

Richard

Imagine how I felt when it happened to me. Fortunately that was at a
coreboot developer meeting and we had the tools to recover in case it
wouldn't have worked.

I had hoped that the option ROM patching was straightforward, e.g.
having LVDS data or somesuch in there. Comparing hexdumps of a
memory-extracted and a biosimage-extracted option ROM showed me that
while the differences are clearly visible, their meaning is not obvious
(it's not EDID). So this method is probably not going to fly.

You can do this with the same flashrom command you used to flash the
image a second time. Please don't use bucts for flashing back from
coreboot to factory BIOS, you only need it in the BIOS->coreboot direction.
That said, I think Vladimir Serbinenko (phcoder) had a trick on how to
modify the original BIOS so that bucts wouldn't be needed any more in
either direction.

Łukasz Dmitrowski is one of our GSoC students and part of his project is
to try to make such stuff easier in the future. He needs data for that,
though.
Richard, could you please collect the following data (as root) from the
system while it's running the factory BIOS?
lspci -nnvvvxxxx
dmidecode
video BIOS via both extraction methods (please make sure that we can
find out which is which)
superiotool -deV
dmesg
/var/log/Xorg.0.log (name may be a bit different, I want a log file from
Xorg running on the machine while the factory BIOS is active)
flashrom dump of the factory BIOS

Please don't send that data to the mailing list, I'll provide some space
for you to upload it.

AFAICS the images you get should be identical. Better check them to make
sure.

Either let SeaBIOS ignore the checksum:
# cbfstool build/coreboot.rom add-int -i 0 -n etc/optionroms-checksum
Or you correct the checksum of the option ROM itself. IIRC there is some
tool to do that, but I coudln't find it in my bash history.

Not sure if all of this is in the wiki. If you think anything is
missing, please tell me so I can add it.

T60 with ATI has black screen

[Richard Simpson]

Carl-Daniel,

I am back in the factory BIOS.  I have gathered the data for Łukasz and
can upload it as soon as you send me a location.

For some reason I couldn't get the option ROM via the Linux kernel, but
only from the mapped memory.  Basically, there didn't seem to be any rom
file in the relevant /sys directory.  See below:

I'll try switching back to coreboot later today.

T60 with ATI has black screen

[ron minnich]

So, can someone remind me, is there no native graphics for the T60? I could
have sworn we got there last time we met. Or even in Berlin.

T60 with ATI has black screen

[Richard Simpson]

Huzzah, it works!  My T60 with ATI graphics is now booting coreboot and
SeaBIOS and I have BUCTS set back to 0.

Thank you, Carl-Daniel, for your prompt assistance.  I can now proceed
to install my final operating system.

I bought a T60 because I read that it was one of the easiest coreboot
laptops.  I dread to think how I would have managed with a difficult one :-)
