[SunRescue] 4/260 speed clocking (adjustable?)

I have an old 4/260 crate that I am trying to get OpenBSD up on.  It runs
SunOS 4.1 fine, but, in loading up Net or OpenBSD, it gets a lot of scsi
dma timeout errors.  IFF there is a way to slow the clocking of the machine
down,  that might give me a chance to see if it is a timing related issue
or something more serious in the code.

Anyone know if any jumpers exist on a 4/260 cpu that will allow slowing
the machine down some?  If so, what jumpers and what positions?
