I'm trying to install a second disk (a Seagate 251-1, 40 Meg) into an
NEC APC IV (which is an 8Mhz AT compatible PC) which already has one
40 Meg hard disk (model APC-H422).  I've checked out the cabling and
it seems to be OK (i.e., each cable works for the first drive).

So far, I have been unable to get the system to recognize the second drive
so that I can initialize it.  The drive is fine -- I was able initialize
it when I removed the first drive and installed the new one in its place.

I suspect that some jumpers need to be set diffently on the first drive
to allow recognition of the second (the Seagate drive has directions for
removing a resister pack on all but the last drive, but there is not such
resister pack visible on the NEC drive).  The NEC system came pre-configured
and ready to run, and without technical specs on separate parts, like the
drives.

The NEC drive has 3 dip switches, one eight switch pack and two four packs,
labeled SW1, SW2, and SW3.  Anyone out there know anything about these drives?

Thanks.
