util/intelvbttool: Cleanup and fixes * Clear remalloced memory * Fix check for invalid VBT offset in header * Fix VBIOS checksum generation * Fix VBIOS size field * Align VBIOS size to multiple of 512 * Reassign pointers after use of remalloc * Don't leak on error path Current version is enough to allow the proprietary Windows Intel GMA driver to find the VBT in the legacy VBIOS area and it doesn't BSOD any more. The LVDS screen remains black, due to an unknown issue with the proprietary driver, while the VGA works. Tested with libgfxinit and native graphics init.

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
coreboot supports a wide range of chipsets, devices, and mainboards.
For details please consult:
ANY_TOOLCHAINKconfig option if you're feeling lucky (no support in this case).
Please consult https://www.coreboot.org/Build_HOWTO for details.
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
