Gene,
If you still want to try it, I did manage to get the old IDE subsystem
working. The issue with pata_amd concerns modprobe.conf. You probably
have an alias to it there, as Fedora seems to insert these. (I don't
know if they're actually needed or not.) If you comment out that line,
then mkinitrd will run successfully, and you can try it that way.
By the way, is there an easy way to use different modprobe.conf files
with different kernels?
Do make sure that you're building whatever drivers you need for your
particular IDE chipset. (This is under IDE chipset support.) I suppose
it's safe to build them all as modules. You may also want to compile
ide-scsi (SCSI emulation support), as some older CD drives seem to need
this, in the form of an "hdx=ide-scsi" command line option.

Yes you do - USB storage and ATAPI are SCSI
By the linux software definition maybe. But I've defined scsi as that which
uses a 50 wire cable using 50 contact centronics connectors since the
mid '70's, and which often needs a ready supply of nubile virgins to
sacrifice to make it work, particularly with the old resistor pack
terminations & psu's whose 5 volt line is only 4.85 volts due to old age.
That's what I call REAL scsi. Its also a REAL PITA if the terms aren't
active.
You can call what you are doing 'scsi' because you are using much the same
command structure, and that is good, but its not the real thing with all its
hardware warts and/or capabilities. For one thing, this version usually
works. :)
Furinstance, you can tell 2 scsi devices on the same controller to talk to
each other, moving files from one to the other, and the host controller can
then goto sleep & the cpu isn't involved until the devices send it a wakeup
to advise the controller that the transfer has been done, and the controller
may or may not then interrupt and advise the cpu. You can do that with
separate controllers too as long as they have a compatible DMA channel
available to both.
I doubt libata has that capability now, or ever will, cuz these ide/atapi
devices are generally dumber than rocks about that. But any device claiming
to be scsi-II is supposed to be able to do those sorts of things while the
cpu is off crunching numbers for BOINC or whatever.
But that puts my mild objections to classifying this as 'scsi' in a more
understandable context. :-)
