Though I assumed »best results« would mean Please don't assume. When something is unclear, creating an opportunity for assumption, then documentation and/or code should be improved, so that no assumption is needed. not that Linux does not find the ROM at all. If that is a known issue, a note should be added to the Kconfig description It's quite natural since coreboot is not equipped to run option ROMs; it does not have any BIOS interrupt services, which option ROMs typically rely on, since option ROMs are a BIOS concept. or if coreboot is chosen as a target, then the Option ROM option should be enabled automatically, right? Which option ROM option are you talking about? Please be specific, use the CONFIG_ name. And since discussion now covers both coreboot and SeaBIOS it helps further if you specify which project the particular option is in. There are use cases both for coreboot running option ROMs and SeaBIOS running option ROMs, regardless of how SeaBIOS was started. I tend to agree that coreboot should default to not run option ROMs, and possibly the SeaBIOS configuration generated by the coreboot build files should enable SeaBIOS running the option ROM in that case, but it's not trivial to find a way that makes sense for every case. Feel free to think about it and propose an improvement, it can probably be better than it is at the moment. //Peter pgpxtLDJoL80L.pgp Description: PGP signature ___ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios

If you want to use the option ROM during runtime, then SeaBIOS (and only SeaBIOS) should run the option ROM. Nothing else will work reliably. SeaBIOS needs to run the rom, because otherwise the 16bit runtime hooks that the option ROM establishes will not be present during runtime. Running the option ROM in both coreboot and SeaBIOS is not desirable, because option ROMs are not designed to initialize the hardware twice - it could easily get confused. So, why does coreboot even have the ability to run option ROMs? This feature is useful when not using SeaBIOS, as it allows coreboot to initialize the VGA hardware. Some programs can talk directly to the vga hardware, but only if the vga hardware has been initialized. This doesn't work for anything that talks to the vga hardware via the VGA option ROM - all of these users must use SeaBIOS and must let SeaBIOS run the option ROM. -Kevin ___ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
