Elilo(3.8) can boot linux kernel(2.6.28) on Intel 945GNT?

[王波]

I'm currently trying on using the ELILO(v3.8) to load and execute an EFI linux(v2.6.28) image on Intel chipset 945GNT.
My native BIOS is EFI BIOS without CSM(Compatibility Support Module).
My elilo.conf is: legacy-free prompt timeout=50 image=vmlinuz-2.6.28 label=linux read-only append="ramdisk_size=12288 maxcpus=1" initrd=initrd-2.6.28.img
I trace the elilo source to elilo.c(255): status = uefi_call_wrapper(BS->ExitBootServices, 2, image, cookie).and the debug info is: util.c(line 318):final get_memmap map_size=1365799604736
//the system hanged here

That is to say elilo.efi has hang before start_kernel().
------------------------------------------------------------------------

Here comes my questions:
Q1: Why does elilo fail when BS->ExitBootServices is called?
Q2: Can EFI Linux Kernel support for IA32 chipsets? or only support for IA64,Itanium, ...
Q3: Has anyone known the differences between IA32 and Itanium in supporting for EFI Linux Kernel?
Any help will be greatly appreciated.

hello unknown,

have a look at this discussion thread, may be applicable to your
situation. A patch for x86_64 is being considered but Ive not yet had
time to test it. and if I intake it i'll port it to ia32 as well.

Q1: Why does elilo fail when BS->ExitBootServices is called?

most likely the elilo memory usage issue especially with a large initrd.

Q2: Can EFI Linux Kernel support for IA32 chipsets? or only support for IA64,Itanium, ...

yes all current efi platforms although ia32 and x86_64 are pretty new
in terms of having actual efi platforms to run on and bugs are showing
up. ia64 has been baked for some time of course being the first efi
platform and the original need for elilo's existence.

Q3: Has anyone known the differences between IA32 and Itanium in
supporting for EFI Linux Kernel?

yes, the elilo ia64 has a kernel relocatable option that was built in
around the 2.5 kernel days when the kernel no longer required to be
loaded at the specific 1mb physical address. this option doesnt exist
in the ia32 and x86_64 branches and elilo got away with the hardcoded
kernel start address until now.

you may find some help from the Apple boards who
have been using elilo-3.6 with some community patches
to run linux on intel ia32 Mac's with rEFIt.
