Re: [coreboot] GRUB2 is too big as a payload in ThinkPad X201

Dear Iru,
welcome to coreboot!

building GRUB directly, I get a different result.
$ git describe

Remove the modules you don’t need. With *my* ASRock E350M1 setup, I
don’t need `pata`, `usbms`, `xfs`, `fat`, `at_keyboard`, `part_gpt` and
`usbserial_usbdebug`. I then add `boottime` and `cacheinfo`.
$ make default_payload.elf
The file is now 578K big and in CBFS the compressed size is a little
over 200 KB.

Re: [coreboot] 'power on after fail' on Panther (Haswell/Lynxpoint)

Currently, the box will power on if AC power is lost and the device was powered on, but not if powered off. I have a use case where it would be convenient to be able to power on the boxes by toggling AC power (eg, the boxes are not within physical reach). I modified the CMOS default setting for 'power_on_after_fail' to be enabled and verified its status with nvramtool. I also tried modifying lpc.c/smihandler.c in the southbridge code to force MAINBOARD_POWER_ON (rather than MAINBOARD_POWER_KEEP) in all cases, to no avail.

Panther does call it8772f_ac_resume_southbridge() which *should* be making the southbridge the one responsible for the power behavior when AC is applied, but as a first test you could try removing that call to see if the default SuperIO behavior is closer to what you want.
Hi Duncan, I tried removing the call as suggested, but it didn't change the behavior at all. Any thoughts as to where to look next?
thanks!

memtest86 reading 0k memory
by Timothy Pearson
All,
I have a board here that loads memtest86 but won't actually test memory.
This is the output:
Memtest86+ v2.11
AMD K10 CPU @ 2312 MHz
L1 Cache: 64K 35028 MB/s
L2 Cache: 512K 6963 MB/s
L3 Cache: 2048K 6052 MB/s
Memory : 0K
|-------------------------------------------------
Chipset :
0K LinuxBIOS
I'm guessing memtest86 doesn't understand coreboot's memory
tables/structure, but I have no idea why that would be. The e820 map is
valid:
e820: BIOS-provided physical RAM map:
BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable
BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved
BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved
BIOS-e820: [mem 0x0000000000100000-0x000000003ffacfff] usable
BIOS-e820: [mem 0x000000003ffad000-0x000000003fffffff] reserved
BIOS-e820: [mem 0x00000000e0000000-0x00000000efffffff] reserved
Any ideas? Other than this one irritating glitch coreboot is working
perfectly on this board.
Thanks!

Re: [coreboot] VGA doesn't work on Mohon Peak
by Kuzmichev Viktor
I tried not to include any VBIOS file in coreboot ROM much earlier, in
my first tests. With 'Run VGA Option ROMs' option checked the board just
hung.
And as I mentioned in my previous email VGA works fine with vendor's
BIOS. So the card itself should be fine.
Sadly, I don't have another card to try. Even if I had, I still would
need to make this one work somehow as Mohon Peak is just a reference
board and the target board will have a similar VGA controller.
So please, let me know if there are some other things I could try or if
I am mistaken somewhere.

Re: [coreboot] Question on VGA BIOS extraction
by WANG FEI
TP X220 suppose to have a UEFI compatible BIOS, is it possible it has a
UEFI DXE VGA driver (not sure what's the proper name of it) except a legacy
video?
Maybe you should boot up system with original BIOS and check the content in
0xC000 segment, is it a legacy VBIOS or it's empty...

Some PCI devices can change their device ID based on a configuration
register or two (I know the XGI Volari can do this for instance). It is
possible that the proprietary BIOS changes the ID for some reason.

Question on VGA BIOS extraction
by Iru Cai
Hi,
I'm trying to build Coreboot for ThinkPad X220. I first backup the vendor
BIOS, then use UEFITool to extract a VBIOS. The romheader program detects
the ROM's PCI data structure and reports the device id is 8086:0106, but
the VGA controller's device id is 8086:0126. I extracted the video ROM from
a running X220 memory and use romheader to test it, the result is still
8086:0106. How could this happen?
