After some experience, it seems that this is not as important on powerpc as it is on x86. That said, i suppose it is possible to set those IRQs from the OF, but i am not sure you really would gain by doing such. I would in any case be especially interested if you hqve proof and experience to the contrary. > * Does the pegasos2 has its own partition scheme for hard disk drives?

It is using the amiga partition table, and naturally both the debian powerpc kernel, the debian-installer and parted/libparted have full support for it. > * Which bootloader will be needed for a pegasos2? Well, work if underway to get yaboot ported, but due to Ethan's tirany, it will never get accepted in the yaboot package, which is a shame. That said, we have a little forth script which does the same kind of work than what yaboot does, and i am working on a little tool generating this forth script from a yaboot or grub like configuration file. > For the installation process I want to prepare (on my debian driven > NewWorld PowerMac) an disk image or some kind of backup archive with all > the packages in place I need for the pegasos. And I want to create the Well, i would do the following. You partition the disk with parted, with either the testing or unstable version of it naturally, make a partition, copy the debian archive on it with debmirror (or download the package, i don't know how your bandwidth is), and then use the netinst beta4 debian-installer on it, and install with the archive on disk method after the reboot. Or simpler yet, just boot the debian-installer beta4 (or latest beta/rc once you receive the board), and follow the instructions, and install the rest of the stuff over the network, but you will get a base system from the netinst CD iso, which is 170Mo or something such. > partitions with mac-fdisk and filesystems on the disk for the pegasos while > this disk is mounted in a firwire-case and connected to the PowerMac. > I'm thinking of this procedure due to the fact I have to setup several more > or less *identical* machines. Well, partimage is your friend, or a setup with DD. That said, you could also use something akind to what the SkoleLinux people use for doing mass install. a prefilled debconf database, and setting the dpkg selections mostly. But forget about mac-fdisk, parted is the way to go. BTW, if you have more info, you can contact me directly, i suppose you know who i am already. Friendly, Sven Luther
