Re: [coreboot] [Bug?] 3 different bytes in VGAbios after upgrade to coreboot

I think the guys used a script to rewrite it to C. I don't remember anymore.

macbook21: broken by 10385 (Make DSDT a file in CBFS rather than embedding it into ramstage.)
by Mono 07 Jun '15

07 Jun '15

Ahoi Vladimir (and all), nice to see you again! my macbook21 lately has two issues: xserver cannot start and poweroff does not poweroff but stops after halt. startx throws the following error: modprobe: ERROR: could not insert 'i915': No such device intel: waited 2020 ms for i915.ko driver to load bisect says: # good: [1cac2c9713a864fe90f40040cd1ede130983544c] Hide PLATFORM_USES_FSP1_1. git bisect good 1cac2c9713a864fe90f40040cd1ede130983544c # bad: [a4cf83df7a3ef3401e12ca3732cbe07294684d02] cbfs: Fix mismerge. git bisect bad a4cf83df7a3ef3401e12ca3732cbe07294684d02 # only skipped commits left to test # possible first bad commit: [a4cf83df7a3ef3401e12ca3732cbe07294684d02] cbfs: Fix mismerge. # possible first bad commit: [1aeea7fbdf252c95e1e3cdf45339a1430125f85d] tpm: Add dummy _DSM to make Bitlocker happy. # possible first bad commit: [36f8d27ea9f741e184b76b5f42d7f777f207edc0] Make DSDT a file in CBFS rather than embedding it into ramstage. 36f8d27 and 1aeea7f had been skipped because of a build error. however, cherry picking a4cf83d on top of 36f8d27 is bad already. So I guess 36f8d27 might be the first bad. Unfortunately I have no idea how to fix the problem or what the problem really is. Can you please point me to the right direction? best regards Mono

Re: [coreboot] [Bug?] 3 different bytes in VGAbios after upgrade to coreboot
by Rudolf Marek 07 Jun '15

Hi all, First byte after IBM is usually a checksum. So in fact only two bytes differ. Now you may ask what it is... and it is a IOBASE :) typedef struct _ATOM_ROM_HEADER { ATOM_COMMON_TABLE_HEADER sHeader; UCHAR> uaFirmWareSignature[4]; /*Signature to distinguish between Atombios and non-atombios,atombios should init it as "ATOM", don't change the position */ USHORT usBiosRuntimeSegmentAddress; USHORT usProtectedModeInfoOffset; USHORT usConfigFilenameOffset; USHORT usCRC_BlockOffset; USHORT usBIOS_BootupMessageOffset; USHORT usInt10Offset; USHORT usPciBusDevInitCode; USHORT usIoBaseAddress; <---------------this changes I guess IOBASE of PCI device changes also... USHORT usSubsystemVendorID; USHORT usSubsystemID; USHORT usPCI_InfoOffset;. USHORT usMasterCommandTableOffset; /*Offset for SW to get all command table offsets, Don't change the position */ USHORT usMasterDataTableOffset; /*Offset for SW to get all data table offsets, Don't change the position */ UCHAR ucExtendedFunctionCode; UCHAR ucReserved; }ATOM_ROM_HEADER; You can use atomDis to dump it I guess (Did not check if it dumps also the header. Thanks Rudolf

SeaBIOS on BayTrail Chromebooks
by Starly Solon 06 Jun '15

06 Jun '15

Hi there, I would like to k ow of there's a version of SeaBIOS that works with the BayTrail Chromebooks and if there's none where could I find information about what's missing? I currently have a laptop with a BayTrail processor, is there a way of dumping the BIOS/UEFI to help (I'm currently running a GNU/Linux distro on it)?
