Hello, as I posted on the blog of Uwe, I have a sony vaio pcg sr1k laptop, and wonder if I could flash it with coreboot. The box has Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge chipset. hovewer the results of the following commands are not encouriging, please tell me if there is any chance to get coreboot working. Please find attached the outpoot of the commands. sudo superiotool -dV > siot.out lspci -tvnn > lspci.out sudo flashrom -V

Our plans are to go through our current product listings and see if we can get FlashROM to work on them. We want to be able to add something other than AMI, Award or Phoenix as a flash utility for our customers. We have been pleased with what the FlashROM utility does and we are working on further validation with this particular utility.

If a specific mainboard was tested and is working, please send a mail containing the mainboard and the flash chip you used, and what you tested on that mainboard+flash combination (verify, read, erase, write) to either coreboot(a)coreboot.rom or flashrom(a)coreboot.rom. Then we can update the web pages accordingly. In case you wish to have new, currently unsupported mainboards supported by flashrom, let us know here, too. I think we can help.

[LinuxBIOS] Add initial support for intel i855gme northbridge
by Jon Dufresne 20 Jan '09

Add initial support for i855gme. This is a work in progress and I don't expect it to work on all boards, or even any besides mine. This is based heavily on i855pm. Signed off by Jon Dufresne <jon.dufresne(a)gmail.com>

#102: flashrom: coreboot ROM image file identification heuristic is broken -----------------------------------+---------------------------------------- Reporter: stuge | Owner: somebody Type: defect | Status: new Priority: blocker | Milestone: flashrom v1.0 Component: flashrom | Version: Keywords: rom image heuristic | Dependencies: Patchstatus: patch needs work | -----------------------------------+---------------------------------------- Non-coreboot ROM images are incorrectly identified as coreboot images, and arbitrary data is used in flashrom code. The heuristic is far too simplistic, we need a proper signature in all coreboot images. The suggested fix is to add a LAR header to the ROM image, I like that too. When an image is incorrectly identified, junk data used by flashrom typically causes flashrom to segfault. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/102> coreboot <http://www.coreboot.org/>

[PATCH] v3: make inline asm declarations consistent
by Carl-Daniel Hailfinger 04 Dec '08

04 Dec '08

v3 uses all combinations of __asm__, asm, __volatile__, volatile and single variations to declare inline asm statements. "asm" is a GNU C extension, while volatile is ANSI C. That means: - __volatile__ can be replaced by volatile unless you use a pure K&R compiler. - asm is not a reserved keyword and should be replaced by __asm__. As a bonus, grepping for __asm__ returns less hits than asm because asm is also used as a normal word in comments.
