Write a segment of C code to send the REQUEST SENSE command over the
SCSI bus.  There might be a way to do this in some sort of "debugger" by
directly writing to the port.

I'd hit HP's support website and see what utilities they already have.

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work.  ;->
