Hi Patrick!
Uhm - I do not explicitly compressed it. I just added it to config..
Extracted it via
echo 1 > /sys/devices/pci0000\:00/0000\:00\:02.0/rom
cp /sys/devices/pci0000\:00/0000\:00\:02.0/rom vgabios.bin
How to check if it's compressed?
Best regards,

That's your problem. ROM needs to be extracted, not dumped. You can
workaround
immediate problem by disabling checksum in SeaBIOS but dumped
oprom for intel is not fully functional, i.a. LCD stays black with windows.

found.
static void *get_intel_vbios(void)

You’ll need something like the following for your device.
config ALWAYS_LOAD_OPROM
def_bool n
depends on VGA_ROM_RUN
help
Always load option ROMs if any are found. The decision to run
the ROM is still determined at runtime, but the distinction
between loading and not running comes into play for CHROMEOS.
An example where this is required is that VBT (Video BIOS Tables)
are needed for the kernel's display driver to know how a piece of
hardware is configured to be used.
(I have no idea how it’s determined at run time though, when to run the
ROM and when not.)
Also, the SeaBIOS logs are still needed to look into this further to see
why SeaBIOS does not execute the VGA Option ROM.
So maybe try first to let coreboot run the VGA Option ROM itself by
selecting `VGA_ROM_RUN`.
Additionally, please post a log with native graphics initialization
enabled. No idea, what USB debug dongle you use, but if you use the GRUB
payload it should be able to deal with the coreboot framebuffer and
maybe even output something over the USB debug connection.
Thanks,
Paul

Thank you for checking that these are indeed the same. From here you
have shown, that the file is not compressed.
Some more comments after looking at your log and config again.

That means coreboot is not configured to run the Video BIOS/VGA Option
ROM.

This is the reason for the error message from `acpi.c`.

As the Video BIOS has not been put into the right place by coreboot
(loading it from CBFS and putting it into memory(?)), it’s of course not
found.
static void *get_intel_vbios(void)
{
/* This should probably be looking at CBFS or we should always
* deploy the VBIOS on Intel systems, even if we don't run it
* in coreboot (e.g. SeaBIOS only scenarios).
*/
u8 *vbios = (u8 *)0xc0000;
optionrom_header_t *oprom = (optionrom_header_t *)vbios;
optionrom_pcir_t *pcir = (optionrom_pcir_t *)(vbios +
oprom->pcir_offset);
printk(BIOS_DEBUG, "GET_VBIOS: %x %x %x %x %x\n",
oprom->signature, pcir->vendor, pcir->classcode[0],
pcir->classcode[1], pcir->classcode[2]);
if ((oprom->signature == OPROM_SIGNATURE) &&
(pcir->vendor == PCI_VENDOR_ID_INTEL) &&
(pcir->classcode[0] == 0x00) &&
(pcir->classcode[1] == 0x00) &&
(pcir->classcode[2] == 0x03))
return (void *)vbios;
return NULL;
}
You’ll need something like the following for your device.
config ALWAYS_LOAD_OPROM
def_bool n
depends on VGA_ROM_RUN
help
Always load option ROMs if any are found. The decision to run
the ROM is still determined at runtime, but the distinction
between loading and not running comes into play for CHROMEOS.
An example where this is required is that VBT (Video BIOS Tables)
are needed for the kernel's display driver to know how a piece of
hardware is configured to be used.
(I have no idea how it’s determined at run time though, when to run the
ROM and when not.)
Also, the SeaBIOS logs are still needed to look into this further to see
why SeaBIOS does not execute the VGA Option ROM.
So maybe try first to let coreboot run the VGA Option ROM itself by
selecting `VGA_ROM_RUN`.
Additionally, please post a log with native graphics initialization
enabled. No idea, what USB debug dongle you use, but if you use the GRUB
payload it should be able to deal with the coreboot framebuffer and
maybe even output something over the USB debug connection.
Thanks,
Paul

Here we go...
I guess cbmem.log should be enough?
Attached one boot with CONFIG_MAINBOARD_DO_NATIVE_VGA_INIT=y set and one
with CONFIG_VGA_ROM_RUN=y and CONFIG_S3_VGA_ROM_RUN=y..
MAINBOARD_DO_NATIVE_VGA_INIT does nothing - display is initialzed as
recently as kernel is already loaded and display driver starts working.
VGA_ROM_RUN at least corectly initialize the display, but - as already
mentioned - no output from coreboot nor seabios is displayed - just a
white blinking cursor until kernel gets loaded.. I guess i have no
timeout in grub2 - so this might be the reason why i also see no output
from grub..

Since SeaBios seems to be bothered about the checksum of the oprom i
tried to disable the checksum_check via:
./build/cbfstool build/coreboot.rom add-int -i 0 -n
etc/optionroms-checksum
But it seems like there is sth. wrong with that vbios.. Multi-coloured
stripes and strange distortions until kernel boots...
I guess i start using UEFITool to re-extract it...
