Exactly, which is why I never liked that idea.

When I go to Debian with this, I'll be asking for a ppcstar subarch to join to
the ranks of apus, chrp, powermac, and prep. All HEC PPC boards will be
PPCStar-compliant. If another manufacturer wants Debian support, they'll have
to address Debian themselves and decide for themselves if they want to
standardize their boot mechanism to make their request more acceptable.

They may not be configurable on a given board, but they are configurable given
an infinite number of boards.

Before I got fired from SBS I was getting ready to work on their new PPMC
boards which have GT-64260 instead of CPC700. While the old ones were only
practically usable as a monarch on a carrier board with useful PCI peripherals
like Ethernet, mass storage, etc. on the new ones they used GT-64260 Ethernets
and on-board IDE (flash disk) on the GT's device bus. This makes those boards
usable as independent computing engines in non-monarch mode where the PCI bus
doesn't belong to them and basically doesn't exist as far as they are
concerned. And those were normal 750CXe and 750FX boards, not 8xx or other very
very embedded stuff.
