I don't use zcpr, so I can't help you on the disk questions, but
cp/m-3.0 gives you, if I remember correctly, a BDOS call which
will perform the BIOS call you actually want.  (number ~50 or so).
Going from 2.2 to 3.0 was great for me, but the things I hear about
zcpr make me think there'd be little reason to choose 3.0 over
zcpr, unless you wanted to take advantage of bank-switching.
