|Taken from YDL 4.0 installation read me
|Rev A iMacs
The Rev A iMac firmware was not designed to recognize drives over 30GB. If
you have upgraded your iMac with a larger drive, it is VERY important to create
a 100MB /boot partition immediately following the Apple boostrap and swap
partitions when creating partitions, as follows:
This forces the location of the kernel to reside on a portion of the drive that
firmware will recognize and be able to use. If you do not do this, your system
will hang immediately following the yaboot prompt.
This is very true. I like this approach better than making a <8GB partition on hda4 and then the rest on hda5. I like to have one root partition. This worked with YDL on my iMac 233mhz, and now I wonder how I set up yaboot, fstab and the boot partition in Gentoo, since YDL did this automatically. How do I get the kernel to the boot partition ? Should the boot partition have a filesystem ?
And don't tell me "You don't need a boot partition on PPC", because I do
