PATA/legacy IDE subsystem on PowerMac
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.

Nothing obvious... the disk seem to be detected properly. Do you have the support for mac partitions and the SCSI disk driver (BLK_DEV_SD) enabled ?
Cheers,
Ben.

The PATA modules was built statically, and BLK_DEV_SD as a module (and not included in the ramfs).
Now it boot correctly, many thanks.
Have a nice day
