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 support
(under ATA/ATAPI/MFM/RLL support (DEPRECATED) ), and the disk is recognized
correctly (hda*).
If we try to remove this legacy support, enabling Serial ATA and Parallel ATA
drivers --> Apple PowerMac/PowerBook internal 'MacIO' IDE (NEW) statically,
the kernel doesn't recognize the partition on the HD. We tried different
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
sda{5,6,7} work.
As you can see from the photos, seems that the hd isn't attached to any device
under /dev.
With request I could upload somewhere the configs (working and not working)
used, but they differ only for the things above.
Please let me in the right direction.
Many thanks to all.
