Hi,
This new patch add the following function to the original x86_64 EFI patch:
1, Fix menu drawing problem
It maps the unicode char to EFI char so that the rectangle box is
showed properly
2, Handle command line option for chainloader command
3, Add new command appleloader
The command is used to enable bios boot in apple's bootcamp, for example
boot from legacy mbr:
appleloader HD
boot
boot from legacy cd:
appleloader CD
boot
boot from usb:
appleloader USB
boot
The usb booting may not work in some machine.

I'm not so sure about that syntax. Is there really only one way to boot
from HD or USB? (for example I've been storing pc-GRUB2 in fat16 header
on third partition, not mbr, and rEFIt finds it there). How does
Windows do it (can we boot Windows using this)? (even though Apple made
BootCamp for windows, I don't want to find out personally.) I guess
you're stuck with some limitations of the apple bios software? Also ,
"appleloader CD" makes me think it should be used even for Mac OS X
boot-CD's, which I doubt it should?

Yes, this is the only way to boot from legacy HD/CD. Refit is using
the same method, but it also writes an embedded syslinux mbr to the
disk, and mark the partition as active, this is how it boots from
different partition.

It can boot both x86_64 and 686 kernel from 64-bit EFI firmware, while
previously it can only boot x86_64.

You should also run ./autogen.sh to update the mk files. Also, I have
uploaded an binary version at:
http://grub4dos.sourceforge.net/grub2/grub.efi.1
You can use it if you still can't compile it successfully.

with just that patch against CVS, for me
- linux then initrd doesn't run out of memory (that fix is still there).
On the other hand, 'linux' with wrong parameters so I repeated the
command, did give me such an error. In any case, trying again perfectly
and booting, gave me the same (as my last test with your EFI patches)
hanging on the GRUB terminal, not booting successfully.
- appleloader always tells me "Model : Core Duo/Solo" and nothing else
(no matter whether I give it a parameter or not). If I say "boot"
nothing happens, it just stays in GRUB prompt and I can enter more
commands. (admittedly, I think I didn't *have* anything to boot in my
CD drive, USB or MBR)

What's the kernel version ? Perhaps you need the latest 2.6.25 series.
Also, you can try adding video=efifb to the command line, does it show
kernel message ?

The model is quite old, it's possible that it uses xom. Is there a
/System/Library/CoreServices/xom.efi in the OSX partition ?

oh, maybe. It's an Ubuntu kernel.

I'll try that soon, does it need any special customization of the kernel?

No, there isn't.. the only .efi file in that directory is
/System/Library/CoreServices/boot.efi

You can try the kernel I extract from Fedora's efidisk:
http://grub4dos.sourceforge.net/grub2/efi.rar
It's 2.6.25. But there is a small problem with this kernel, the screen
would scramble after some kernel output. This is caused by the agp
driver, not grub's fault.

Interesting, according to refit, this should be an early 2006 model.
Refit does work, doesn't it ?

Results:
Whatever linux kernel I pick, adding video=efifb to its commandline
causes grub to output a couple extra lines in response to `linux`:
Video mode: 1280x800-32@59
Video framebuffer: 80000000
Even with video=efifb, the Ubuntu kernel works no better. But that
Fedora kernel you mentioned, does work:
- with video=efifb, the penguin and kernel messages flash onto the
screen for a moment before the screen turns into gibberish.
- without, the screen just turns into different gibberish, which is
still an improvement over the GRUB screen remaining there :-)
Of course, that Linux kernel doesn't bring me to anything *usable*...
but it shows that we're loading Linux and it's probably possible to work
in practice by compiling a new enough Linux with the right configs (and
maybe patches)

refit doesn't tell *me* anything about the model when I'm in refit. In
case what your appleloader says was confusing you, I actually have a
2.16 GHz Intel Core 2 Duo CPU (yes, 64-bit capable, I've just never used
it in that way). I'm still running refit 0.9 though since I never yet
bothered to upgrade to 0.10 or 0.11, and since it works fine for me.

I'm using the 2.6.25 kernel from debian sid, it works fine. I think
ubuntu can use debian packages as well. To solve the screen problem,
you need the following command line:
video=efifb agp=off
If you're interested, you can also try amd64 kernel. You can use it on
686 linux directly, no need to install a full amd64 system.

I take a look at 0.9 source, the handling is the same. Are you sure
you type the command exactly as it is ?
appleloader HD
boot
You can also try my compiled version, see if it works.

what should I expect the result to be, given that refit is the only
thing that's ever touched my MBR since Apple's manufacturing? (so
there's a fake partition table created by refit's gptsync, and maybe
there's whatever you were saying about refit using hacks with the mbr to
boot grub-pc from my third partition, but I've never specifically
installed any bootloaders to this mbr)

every time I've tried Ubuntu with a different kernel... it has problems.
Ubuntu has a fancy initrd, modules, lots of patches, Upstart as init,
and who knows what assumptions about the boot process... but maybe. I
could use the kernel from the Ubuntu development branch, if I had any
idea how to use APT to upgrade just a few specific things from an
unstable package-source and not my whole system (the kernel binary
obviously doesn't depend on system libraries, so it should be uniquely
easy to do this...). Do you know about debians -- if that's possible?

Perhaps command line is not passed to loader correctly, you can verify
it with the OSX loader:
set root=(hd0,2)
chainloader /System/Library/CoreServices/boot.efi -- -v
boot
Please try this out, if parameter -v is passed to the loader, you will
see console screen before switching to GUI.

In debian, all I have to do is to add the sid line to
/etc/apt/source.list, apt-get update, then apt-get install
linux-image-xxx. Ubuntu is based on debian, the process should be
similar.

That 'chainloader' didn't work at all: It seems GRUB2 here isn't
understanding the HFS+(journaled) filesystem at all. Neither in EFI nor
BIOS grub2 can I see anything on that partition, even though I have
module hfsplus loaded (I think - but lsmod in grub takes up more than
the whole screen, so I can't see them all - is there any way to get
around that?).
Also I decided to play around and try a few other commands in grub2.
cpuid (efi or pc) -- finishes instantly without outputting anything
lspci (efi) -- hangs (but it works properly in pc)
reboot (efi) -- hangs (but it works properly in pc)

yes it is similar (and I'd probably try and use the Ubuntu development
branch for the next release, "intrepid") : however, what bothers me is
that this seems to make the whole apt repo, not just the part I want, be
a first-class citizen; so that if it contains a newer version number of
any package on my system, it will install that if I ask to install the
package, or it will offer to upgrade to that version if it's already
installed (so I can't even begin to pick out which are the Ubuntu-stable
updates). I hope I'm missing some option that lets me avoid this risky
nuisance, while still keeping tabs on the unstable linux-image packages?

I wonder if there is bug in the hfsplus module. You can check it out
with grub-fstest command:
sudo ./grub-fstest /dev/sda3 ls /
This would list the content of root directory.
You can also create a small hfs+ image and test it with grub-fstest,
if it does have problem, you can upload the image for me to test.
cpuid would check if cpuid exists and set return code, there is no output.
The result is lspci is a little strange. Is there any output before
hanging ? When you use video=efifb or video=vesafb. It enum pci to get
the frame buffer address, if it doesn't hang there, it shouldn't hang
here as well.
reboot could be a firmware related issue, I can check it out.
Oh btw, do you compile from source or use the binary version ?

Perhaps the most simple way is to download the deb package from
intrpid, then install it with dpkg.

outputs nothing, just a blank line, for /dev/sda2 which is my hfsplus
(it works fine for fat16, ext3 partitions).

not sure how to create a hfs+ image... the one I have is many gigabytes
and came with the laptop (I just shrunk it to 30GB to fit my linuxes, is
all). Does Linux or MacOSX provide a way to create a small HFSJ image?
(also I could try going to MacOSX and turning off journalling and see
if it affects grub2's ability to read it at all, perhaps - although for
just reading, not writing, I doubt it makes a significant difference)

odd, because that definitely didn't hang (when loading linux-2.6.25 that
is).

Hi,
Perhaps you can also try the binary version at:
http://grub4dos.sourceforge.net/grub2/grub.efi.1
A friend of mine have tested in in 32-bit EFI firmware, there is no
problem for him.

I am not sure if appleloader is a good word. Can you explain how it
works and what it actually does? Perhaps something like "legacy"
would be a better word, especially since it is not apple specific.
btw, you forgot the changelog entry.

It only changes term/efi/console.c, which is efi specific.

The code is apple specific. They use special pathname for the bios
switcher, we just chainloading it. The pathname is not even the same
among different models, we need to go through an array to find a
possible match.

It confuses me! I could boot it from refit as EFI. Then it claimed to
be GRUB 0.97. The "help" looked slightly different that what I was
familiar with (but I've never used grub1 so I don't know...); and
`reboot` worked. I didn't test more yet.. should I?

Hi,
That's the fedora efi loader, have you used the right file ?
BTW, you need to rename it as grub.efi, refit can't find files with .1 suffix.

Oh nice. What about hfs+, can you read files from the osx partition ?

This command is firmware related, some model may not work.

intelfb doesn't work. The only way to see console in efi is to use
video=vesafb or video=efifb. grub2 will detect these options and setup
frame buffer for you. You also need to use agp=off to disable agp.

How come? I thought intelfb used the bare hardware.

Can you be more specific? I thought grub was completely agnostic about Linux
parameters.

The video register in efi mode is not setup in the same way as bios.
There are two sets of register. In EFI, set A is completely zero,
while set B have non-zero value. But in bios mode, both set have
non-zero value. I guess this is because bios have text and graphic
mode, while efi only have graphic mode. (text mode in efi is emulated)

In the parameter passed to linux kernel, there are fields for video
adapter information, for example, frame buffer address, line length,
etc. Normally, we don't have to worry about it, but in the case of
efi, we must fill it in, as kernel can't detect the information
properly.

Hi,
BTW, it's the real mode part of Linux kernel that takes care of such
job. It gathers video information by querying vbe. But in efi, we skip
the real mode part and jump to protected mode directly, so we must
also provide kernel with similar information that would be setup by
the real mode part.

But isn't intelfb supposed to access the hardware without any support
from bios/vesa or efi?

Intelfb uses the environment setup before, it doesn't try to
reinitialize video registers.

Hi,
I think the real problem of intelfb is that it uses agp, which
requires video hardware to be configure properly. But if we use vesafb
or efifb, it uses the frame buffer, so as long as we setup video
information properly in grub2, we can see console output.

Ah, I suppose this explains why Linux crashes when we try to load it via
grub-linuxbios (I reused the i386-pc loader when doing the port, unaware
that this would be an issue).

Hi,
Here are the information gathered in real mode:
memory map information
video information
monitor information (edid)
hard disk information
perhaps more
The first two can be retrieved in grub, others are optional, kernel
can normally get the value itself.
Perhaps we can write a generic protected mode linux loader for i386.
Functions such as claiming memory, getting memory map and the like can
be wrapped in platform dependent call arch_xxx.

Seemingly, the fact that there is now separate recognition for "x86_64"
machine types has borked the current build system in amd64 PCs:
$ make
./config.status --recheck
running CONFIG_SHELL=/bin/bash /bin/bash ../src/configure
--prefix=/home/javier/Proyectos/grub/build/out/ --no-create
--no-recursion
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
configure: error: unsupported machine type
make: *** [config.status] Error 1
The current system would build bootloader files as i386-pc (with the
-m32 switch in gcc, which itself created the infamous "cannot find start
or _start" problem when a multilib version of gcc was not installed) and
helper files like grub-setup as amd64. This caused problems of its own,
like grub-emu (built as amd64) being unable to load any grub modules
(built as i386), but at least worked OOtB.
I was able to correctly recompile if I reconfigured GRUB with
--target=i386-pc-linux-gnu (i386-pc alone was not recognized). Is this
the current way to go? I feel it should not be so, because it multiboot2
comes out with amd64 support, there should be an x86_64-pc grub2.

Hi,
To compile 32-bit efi:
./configure --platform=efi --target=i386
To compile 64-bit efi:
./configure --platform=efi --target=x86_64
This works in i386 and x86_64 host. If you don't use --target, it will
build native image.

I've just noticed that. I think x86_64 should default to "i386-pc"
platform. I'll have a look how to do it nicely.

I was trying add an extra check there, but ran into more interesting
stuff. Basically, the target checks should be better separated from the
rest. I'll take another look.

I didn't know grub-emu could load modules! Live and learn :-)

Perhaps we'll have it eventually. But I agree, the default should be
restored for now.

I have the following in configure.ac:
if test "x$platform" = "xefi" ; then
case "$target_cpu" in
i386) ;;
x86_64) target_m64=1 ;;
*) AC_MSG_ERROR([unsupported CPU type for EFI]) ;;
esac
else
case "$target_cpu" in
i386) ;;
x86_64) target_cpu=i386 target_m32=1 ;;
powerpc) ;;
powerpc64) target_cpu=powerpc target_m32=1;;
sparc64) ;;
*) AC_MSG_ERROR([unsupported CPU type]) ;;
esac
fi
If platform is not efi, x86_64 will become i386, perhaps there is
something I miss ?

It won't. There is no default defined for x86_64. I'm fixing it now.

It does not reach that point, the "unsupported machine type" message is
thrown by this earlier check (line 59)
# Guess the platform if not specified.

I think this one would be better, as it follows the structure what's
done with i386: vendor=apple -> efi; anything_else -> pc. Also, this one
errors out with a more understandable message that does not conflict
with another check some lines down.

Dunno if you read the latter patch, but nevertheless those three checks
have some nasty circular dependencies. Besides, now that we're talking
about the build system, the Makefile.in file refers to the inexistent
conf/i386-coreboot.rmk file, and that's affecting every other system
because make "can't find a rule to make conf/i386-coreboot.rmk, required
for conf/i386.coreboot.mk. Halt" - I suspect a rename to/from
conf/i386-linuxbios.rmk file was left incomplete or is still uncommitted
to SVN.

That's a good call. I'm working on a more radical patch now. I'll post
it for review.

I agree that the messages should be improved.

That's misleading. We can guess platform for any supported CPU (well,
we try out best). The real problem is that the CPU is not supported,
and that's what the message should say.

I was wondering if maybe it would be simpler to emulate the BIOS (and use
stubs where suitable). Memory map would be simple to produce since we
already have this information which we used to initialize our heap. As
for video information, do you have more details (or know a document that
explains what's probed for)? If it's only for vesa modes maybe we could
just stub it.
