Hello,

I hope I've posted to the right list.
I'm the maintainer of the linux kernel in ArchlinuxPPC [1].

We actually set statically the support for the PowerMac on-board IDE suppor=
t=20
(under ATA/ATAPI/MFM/RLL support (DEPRECATED) ), and the disk is recognized=
=20
correctly (hda*).
If we try to remove this legacy support, enabling Serial ATA and Parallel A=
TA=20
drivers --> Apple PowerMac/PowerBook internal 'MacIO' IDE (NEW) statically,=
=20
the kernel doesn't recognize the partition on the HD. We tried different=20
powerbook, and the result is the same.

Because we haven't log, I take two photos [2] [3].

With legacy stuff, I used hda6 as root device: with PATA, neither hda{5,6,7=
} or=20
sda{5,6,7} work.
As you can see from the photos, seems that the hd isn't attached to any dev=
ice=20
under /dev.
With request I could upload somewhere the configs (working and not working)=
=20
used, but they differ only for the things above.

Please let me in the right direction.
Many thanks to all.
