[Mactel-linux-users] Booting GNU/Linux CDs from an external optical drive

[Sebastian T. <se...@sm...>]

Hi all,

I have an aluminium Macbook Pro (Jan 2008) with a broken internal optical
drive.

I can boot from the Snow Leopard install DVD using the external optical drive
without any problem whatsoever but it simply will not boot from any of the
GNU/Linux boot CDs I have at my disposal (Debian Squeeze, Debian Lenny, Ubuntu
9.0, I've even tried a GParted Live CD).

The result is always the same - rEFIt identifies the CD as a GNU/Linux boot CD,
I select it, hit Enter, smile at Tux in the middle of my screen...  but then
everything goes black and I'm presented with the depressingly unhelpful error
message "Missing operating system".

I've synced the partition tables, the EFI firmware is as up-to-date as it can
be, I've even tried a bootable USB flash drive or two - again rEFIt identifies
the media correctly - but then... nada.

Any advice/tips/pointers/suggestions very much appreciated.

Sebastian

That is one option.

If speed is not the issue, USB-to-Ethernet dongle is another option.

My old MacBook does not even have expresscard slot but I could manage
this way when I was playing :-)

[Mactel-linux-users] Debian on the MacBookAir3,1

[mike d. <fl...@po...>]

Hi there,

I'm trying to get Debian to work properly on one of the new MacBookAir
machines. I've started documenting my steps so it can be of some use to
someone eventually: http://dentifrice.poivron.org/laptops/macbookair3,1/

It's a work in progress, quite a lot of things need to be fixed and/or
figured out still and I'm running out of time to play with it, so
contributions more than are welcome!

Cheers,

[Mactel-linux-users] status of iMac 11,3 (27" - mid 2010)

[mike d. <fl...@po...>]

Hey there,

In spite of some browsing, I haven't been able to find any information
regarding the use of GNU/Linux (be it Debian or Ubuntu) on the high-end
iMac models which last came out (iMac 11,3; 27"; mid 2010; with either
HD 5670 or HD 5750 for graphics).

I'm considering getting the iMac 11,3 with an i5 or i7 processor (I
don't care much about the graphics chip, provided it works with open
source drivers and provides accelerated 2D graphics - 3D not being
important for me right now).

I'd be glad to read stories, be they successful or not, and/or be
pointed towards documentation I may have missed. A thread [1] on
ubuntuforums describes a persistent "black screen" issue on the iMac
11,1 model. However, there's no mention of the 11,3 model, which ships
with different graphics as stated above.

Thanks a lot in advance for your input!

I did not do this ...  but there are other option.

But I have used USB-Ethernet dongle with my macbook without any problem.
(Not that I needed it but just checked it when I bought that for my
other PC without any expresscard nor PCMCIA.  Oh my macbook lacks
them too)

[Mactel-linux-users] No video signal unless booting Linux

[Tino K. <tin...@ti...>]

Hi,

after playing around with grub-efi, and fixing grub-install in Debian
sid, I know have hosed graphics in my Mac mini Core 2 Duo. I don't get
a video signal after power on, in the EFI menu, in grub-efi and when
booting OS X. There are two ways to restore the video: suspend in OS X
and resume, or boot Linux.

I was suggested to reset the NVRAM, by using command + option + p + r
after power on. However, according to the instructions I should hear
two beeps if the reset was successful, and I don't hear the beeps. So I
don't know if the reset really happened. I have a PC keyboard, so I use
windows + alt + p + r. Should this work? Should I hear the beep on a
Mac mini? Any other hints to restore the video? I already pressed the
power button after removing the power cord.

Regards,
Tino

ah.. yep I haven't yet compiled grub2 with efi,
(maybe)causing the stuckage with efifb, but then again
I tried with nvidiafb, and hit the same green colored
stuckage(but could be wrong), leading me to believe
just a simple adding of an address but then again

In any case I'll try to work this..
(be nice to get some patches sent upstream
for this area).

Right. The partition limit is not a big deal for me, and I don't mind
about the faster bootup procedure, but is there another obvious benefit,
or any drawback for that matter?

Ok. So - what is the EFI system partition for? Seemed like a good place
to put EFI applications, but when I mount it under Debian, it shows
empty, while there's an EFI folder in it when I mount it under MacOS X.
Any eplanation for that?

Here goes the grub config for my MacBook2,1. I tried to use the BIOS
dumps, but it wouldn't work, and it turns out I don't need them to boot,
since 'fakebios' is sufficient:

	menuentry "Debian Squeeze" {
	  fix_video
	  fakebios
	  linux /vmlinuz root=/dev/sda4 video=efifb
	  initrd /initrd.img
	  }

AFAIK, fix_video is only used to fix the grambled screen during the boot
sequence, and is not necessary if you don't care about the text console.

Yes. You need to either compile grub2 with '--with-platform=efi' or use
the grub-efi package if you're using Debian or Ubuntu. See instructions
on http://grub.enbug.org/TestingOnEFI and more Macintosh related details
on http://grub.enbug.org/TestingOnMacbook.

It would sure be nice to know (and possibly get it fixed upstream). I'm
assuming your machine has 64bit EFI (my Macbook2,1 and Tino's MacMini
use 32bit EFI, AFAIK).

  If this then is not the case, then(probably) my machine needs to  
have the framebuffer address added to efifb.c

Thanks for the info, Ill have a look, and see.(BTW:threads proably all

Instructions for what? I just boot an unpatched kernel which uses
kernel mode setting for intel graphics.  However, I needed to include
this to my grub.cfg:

search --set -f /boot/vbios.bin
insmod loadbios
loadbios /boot/vbios.bin /boot/int10.bin

Cool.. was looking into using efifb on
the iMac9,1 but had no luck. Either
my grub2 needed to be built with
efi support and/or I needed to add the device
address to efifb.c

What/where are the instructions?
I'd like to see if either it's a simple
configuration and/or if a patch needs
to be created for efifb.c and pushed
upstream for these devices(only a few
in there I see now).

I didn't try efifb. I just use the DRM framebuffer along with kernel
mode setting, which is also used by the native Intel driver in Xorg.

You don't have to mess around with gptsync, which is limited to 4
partitions.  And in my setup, it created a dummy partition before the
EFI partition, lowering the limit to 3.  Also, there is no delay at
boot time which is caused by the legacy BIOS.

I created a small HFS+ partition only for grub. It has no journal, so I
can also write it in Linux to update grub or modify grub.cfg.

Thanks for sharing that with us. 

Booting my MacBook2,1 with grub-efi had been on my TODO list for a while
(especially since it seems to be the only way to boot from a USB stick,
and to allow grub to see and therefore access anything else than the
internal hard-disk).

So, I finally found a bit of time to try it, and successfully booted
Debian with grub-efi installed on a USB stick (using 'fix_video' and
'fakebios' in the grub menu entry) while retaining grub-pc on the
hard-disk for now.

So far, everything seems to be working : efifb provides a nice textmode
console, and X.org using the 'intel' driver runs seemingly just as fast
as when legacy booted (judging by the output of glxgears).

However, a few questions remain for me:
- what are the actual advantages and drawbacks from booting in EFI on
  such a platform?
- where is it best to put the grub.efi EFI application? is it advised to
  have it sit on the first EFI system partition, within the EFI folder?
- if not, where?

[Mactel-linux-users] linux support for GPU switching in latest Macbook Pro models

[mike d. <fl...@po...>]

Hello,

As you may know, some of the latest Macbook Pro models (MacbookPro6,2)
carry two graphical chips, one being Intel, the other being Nvidia.

While initially rumored to be powered by the Optimus Nvidia technology,
Switching between the two is actually done in software.

I've been trying to find information on potential Linux support for
this, but found nothing yet (other than one report saying the intel
graphics didn't even appear in the device list under GNU/Linux).

Does anyone have more information, and/or one of these new models? It
looks like people at http://linux-hybrid-graphics.blogspot.com/ could
use some dumps…

Thanks,

I usually use the ohci1394_dma=early boot option via firwire.
that is if the machine crashes early I can see whats going on.
(hopefully)
In your case you probably already have dmesg since the machine
starts up(if this is the case), and then after done with everything
reboots(saving the log file (but could be wrong)).

also looking through bugzilla I think your hitting this:
https://bugzilla.kernel.org/show_bug.cgi?id=14952

(maybe revert this commit and see if you boot up)

Not exactly sure how to go about that.  I will try to video the boot 
process so I can provide better info.

so changing your grub at-least takes care of the unable to find
VFS thing?!
and now the system boots up, and then instantly
reboot's? I have seen reports of things like that,
but have never hit something like that(if you can try early debugging 
with a remote machine to grab dmesg)

I changed my grub entry for root from:

root=LABEL=/

to

root=/dev/sda8

Now I get a spontaneous reboot.  I tried to snap a photo of it before it 
reboot, but it's blurred.  I'll try again.  Weird thing is that it says 
something about wacom driver and then a reference to reiserfs or some 
such.  I don't know what the wacom driver would have to do with 
reiserfs, but I'm not using reiserfs anyway.

hm.. I'm wondering if your hitting something
with grub and the kernel i.g. I remember hitting something
similar because I had no bzimage just raw make install
vmlinuz(ended up having to upgrade to grub2 so that grub(*)
was able to read the extra bits and so forth or something
in that area).

Also hit another issue similar as well with
PCI_MMCONFIG [=y]
(but this could already be fixed).
