Re: [SeaBIOS] [coreboot] UEFI project ideas

[Martin Roth]

      Here's a patch to build the UEFI coreboot payload package directly as a
coreboot payload.

 I probably do not. ;-)

  And what has all this to do with seabios?
 Did I ever mention SeaBIOS to play minimal TianoCore?

 Thank you,

  These are the opposites: SeaBIOS is CSM ON
(emulates Leagcy BIOS),
 while Tiano Core supposed to be CSM OFF (UEFI), Thus, SeaBIOS and
 Tiano Core exclude each other (should not be used together -> wrong
 architecture).
 I fail to see what you are trying to tell me.

  The point is to make minimal Tiano Core (minimum
for making FAT32
 partition/file system on HDD/SDD to create /boot/EFI/ directory, in
 other words minimal UEFI compliant BIOS), Tiano Core as such is good
 to be used/run for/on x86 architecture ONLY (and side effect is the
 extended time for booting, since all these DXE drivers must be
 installed, which will be later mostly replaced/run over with OS
 drivers, except run time services).
  As such, Minimal Tiano Core (minimal UEFI
compliant BIOS) could be
 used on ARM architectures too, thus making ARM HW platforms also
 compatible/lookalike as x86 UEFI compliant BIOS.
 tianocore already runs on arm.
 seabios doesn't and it never will.

  In nutshell, then you can build PC/Laptop with
ARM CPU/SoC HW
 platform, having coreboot + minimal Tiano Core + WIN 10 Boot Loader +
 WIN10 on it (since WIN10 BL does see UEFI compliance, not knowing what
 is really under the hood). ;-)
 And what has all this to do with seabios?

 confused,
