grub hangs without error on mac mini

[andreas]

Hi

I've a problem with grub on my computer. Please let me know, if I should 
ask somewhere else or if this is the right place. Thanks.


I've just installed (LFS) Linux on a new Mac Mini (Intel) but the 
computer doesn't start (no OSX, only one partition for Linux). All I see 
is:

 GRUB Loading stage1.5.
 
 
 GRUB loading, please wait...


There is no error message, nothing. I'm a little bit puzzled, as this is 
not the first Linux system I install, but the first time I don't know 
what to do.

I use grub-0.97 (with two patches, see the LFS page: 
http://www.linuxfromscratch.org/lfs/view/development/chapter06/grub.html)

The partition to boot from is /dev/sda1 and in my grub menu is

 default 0
 timeout 10
 title LFS
 root (hd0,0)
 kernel /boot/lfskernel root=/dev/sda1

The file does exist and I installed grub in the grub shell with "root 
(hd0,0)" and "setup (hd0)".


Just to make sure, I installed ubuntu (7.04) on the very same computer 
(they use grub too) and the system starts, without problem. So the Mac 
Mini does start some Linux with grub, it's just my installation.
I have a MacBook running with LFS and grub, there isn't a problem 
either.

So, why is grub hanging there (I rebooted after 10 minutes)? What might 
I do to solve the problem? What is grub waiting for?


Thanks for any help,
Andreas
