RE: booting darwin

I have Windows and Linux on hd0 and Darwin on hd1; the boot partiion is on
(hd1,0) and root is on (hd1,1). Grub does not boot Darwin with or without
the makeactive command. I get the same "Load error
..............................=>". If I use the tab key to look at the
partition information, for (hd1,0) "Filesystem type unknown, partition type
0xab" and for (hd1,1) "Filesystem type unknown, partion type 0xa8". With
rootnoverify (hd1,0)/(tab) or (hd1,1)/(tab) the message is "cannot mount
selected partition".

Ok

What do you mean by "identifier"? Partition type? What exactly did you do?

Seems to be ok.

I had quite the same entry. This is the canonical way to chainload a not
supported OS. I'm not shure if makeactive is necessary or even wrong.
Try to comment it out.

BTW, the complete grub.conf would be helpfull.

The first thing you should do when you have problems with grub: command
mode. When you got the menue mode, hit c. Then you should see some kind
of text shell. A help command is available. You can use tab-completition
as well. Try to find your Darwin partitions.
You can identify them by "looking inside" the partitions:
rootnoverify (hd<tab>1,<tab>1)/<tab>
you should see some directories.

The boot partition has to be a primary partition. I installed the system
partition into a extended partition, and that worked. But I think there
are issues with 8GB boundaries and the like (simple boot loader).
