Re: [coreboot] The OS of open source solution

[Stojsavljevic, Zoran]

Hello Tank,

In regards what I said yesterday, here are some new facts I have learned in the meantime.

For Windows 7, it has two boot modes: legacy 32-bit boot mode, and UEFI 64-bit boot mode.  The former/legacy boot mode boots from any legacy BIOS (SeaBIOS, AMI, Intel, etc.), and the latter one requires few UEFI run-time services.   They say that Windows 8 only boots from UEFI, but it might be possible to boot with SeaBIOS using 32-bit Windows is becoming possible.  Run-time services will not disappear during or after boot, but all other boot firmware will.

I am using 64bit Win7 and Win8, and this is the reason why I am not able to boot, since both 64bit mode Win7 and Win8 require few run-time services (from the first paragraph), which DXE phase (absent in FSP) provides.

So, what I do suggest is to try with fsp (32bit) -> Coreboot (32bit) -> SeaBIOS (32bit) -> Win7 (32bit), in theory what I wrote here it should boot!

Tiano Core. The group doing this in INTEL is another galaxy, so I am not too much familiar with their work. As Tiano Core supposed to support EFI/UEFI interfaces, and certainly DXE phase, so it should seamlessly boot. PEI phase should provide linked list of HOB pointers (the head) to DXE (For PEI phase, the PEI service GetHobList() can be used to retrieve the pointer to the HOB list.  For the DXE phase, the HOB list pointer can be retrieved through the EFI System Table by looking up the HOB list GUID in the System Configuration Table. Since the System Configuration Table does not exist that the time the DXE Core is launched, the DXE Core uses a global variable from the DXE Core Entry Point Library to manage the pointer to the HOB list).

Best Regards,
Zoran

Hi all,
    Now I can install&boot OpenSuse with "coreboot(intel fsp)+seabios".
    For win7 & win8 ,I think that tianocore as payload is a better way. Intel Fsp provide HOB pointer,we maybe need to hand off this to DXE pharse and then do mainboard init .....

Hi Zoran,
    What do you think of this idea? 
Thanks,
TankTang

Win8 seamlessly boots with IVB CRB with EFI BIOS. Knowing that Win7 requires EFI or UEFI BIOS (mandatory using EFI/UEFI BIOS drivers), I did not expect Win7 to boot. The pleasant surprise was that Win7 bootloader tried to boot Win7, concluded that Win7 is broken/damaged (NO EFI drivers), and safely redirected me back to Win7 bootloader VGA screen asking me for the options:

I assumed (exchanging some thoughts internally with some designers) that Win8 is "dual", so it'll go to discover EFI/UEFI, but if it fails, it has different mechanisms to boot without EFI/UEFI. I tried to boot 3 times. All three times the blue Win8 flag/logo appeared with the message: Preparing Automatic Repair. And froze.
