It depends which version of Apple Pascal you are talking about.
Apple Pascal 1.3 added support for booting from devices other than a
5.25" drive (and built-in support for using the ProDOS block driver in
other interface cards).
Earlier versions only support a 5.25" drive for booting, but a driver
can be loaded during boot to allow data-only access to other drive
types.
All versions require disk controllers (for the built-in driver) to be in
slots 4, 5 or 6. Loaded drivers may be able to support other slots for
data-only access.
