What disk controller do you have?  That's the biggest issue.

Nothing oddball except I had to have the right type of tape controller
to boot my install tapes (MS vs MT) and I had to have enough storage
on a supported controller.  There was no MSCP support for 2.9BSD in
those days.  There are modernish patches now.  I did my install onto a
pair of RL02 disks (because I didn't have an RK07).  You will need
more than 10MB if you want to rebuild the kernel, but you can put the
install kernel on a 10MB disk and noodle around.  ISTR there's support
at install time for a number of types of system disk, but RK05 was now
too small.  There are also 3rd-party ESDI and SMD controllers that
would work.
