Re: some basic questions for CoreBoot experts

There are some functions in the source code of coreboot version 4 which have not defined any where like pci_get_dev(), What does it mean? Is Coreboot-V4 is incomplete? coreboot v4 is complete. pci_get_dev is only used in userspace software which is independent from coreboot. Is coreboot using some ...

Re: New flashing program for DOS/Linux/FreeBSD/NetBSD/MacOSX

Thanks! By the way, you might be interested in adding http://blogs.coreboot.org/ to your blogroll. It has various BIOS-related topics (flashrom, coreboot, UEFI, SeaBIOS, ...) and we already link to http://www.wimsbios.com/blog/ on that page. There are so few BIOS-related blogs out there that we shou...

Re: How is data in a BIOS organized?

thanks Sharky You're welcome. Apparently something is screwing up the flashROM. Afik there are no viruses around who would do this. Maybe the flashROM is worn-out (they do last long but not forever). A few really old viruses erased the flash chip (CIH virus), and in theory it would be possible for ...

Re: Reg Bios Runtime calls

For a classic BIOS and a good 32bit/64bit operating system, no direct calls to the BIOS will happen outside operating system startup. The BIOS can intercept some hardware accesses with SMM (to emulate hardware etc.), but the OS will not notice that (SMM mode is invisible to the operating system). Be...

Re: How is data in a BIOS organized?

My question(s): can anyone tell me where data is stored in a BIOS? Is there a guide describing the ins and outs. Can I just copy this address range (00000x-1FFFF) from the original ROM file to the upgrade file? Or does this mess up a checksum? I don't know of any guide, and every BIOS does this in ...

Re: Coreboot, what's the deal?

I am trying to port coreboot r5039 to intel atom n270 , + 945GSE + ICH7M based netbook. I am able to compile the code with no error. But after porting it to netbook, I am not able to see any thing on my LCD and VGA port. Yes, that is expected. Turning on LCD/VGA happens only as one of the last step...

New flashing program for DOS/Linux/FreeBSD/NetBSD/MacOSX...

Hi, flashrom ( http://www.flashrom.org/ ) recently got support for DOS (it has been available for Linux/FreeBSD/NetBSD/MacOSX for quite some time). I thought maybe some people would be interested. Advantages: Free Support for pretty much every modern flash chip (especially SPI flash) Support for pre...

Re: How to fix a corrupted bios flashing?

I tried force flash and NOTHING You could try flashrom ( http://www.flashrom.org/ ) under DOS/Linux/FreeBSD/NetBSD/MacOSX/whatever. If it finds the replacement chip, there's a good chance you can flash it. The downloads there are source code only, so if you want a ready-to-use binary (.exe or whate...

Re: Converter wph --> bin need!

Could you help me with how to convert .bin file to .wph? Sorry, that is not possible without detailed board information (and no, the board name, chipset and configuration are not enough). Besides that, .wph is undocumented and a manually created .wph has the risk of bricking your computer. Why woul...

Re: Converter wph --> bin need!

Grateful for any pointers for converting the Sony Vaio .wph to .bin Usually the easiest way is to check the file size (in kB) then round it down to the next power of 2. Examples are 128, 256, 512, 1024, 2048, 4096. The rounded down number is the destination file size. Then you run (Linux/*BSD/Solar...

If someone has a copy or a similar tool (or just the needed info/source to create a new version), please post it here.
I think the bios_extract tool mentioned at http://libv.livejournal.com/19066.html can handle Dell BIOS as well. No guarantees, though.
