I still think you have cabeling problems. Note that the DB25 of the U5 /
U10 has the same pinout as a PeeCee (DTE) but the "wrong gender". It is
no DCE pinout like on a modem. Maybe you should try cu(1) or tip(1)
instead of fo minicom(1).

It should. Maybe the disk has problems because it is LVD and you
connected it to a FAST-10 bus? Maybe you need to set a jumper to force
the disk to Single Ended mode.

The A180 has PCI Ethernet and the port of the OpenBSD PCI code is still
in progres. (Actually I didn't had the time to work on it for some days
now.) PCI devices are recognized now, but interrupt routing does not
work. (OpenBSD and NetBSD differ quite a bit in interrupt routing on
hp700 hardware.) There is also a problem with the mii/phy part of the 
Tulip in hp700 and NetBSD. NetBSD doesn't recognize the phy chip type...
So I am afraid to say: There is nothing real usable now, but you can
expect somthing within a few weeks.

There is no special kernel needed for netbooting. Ususally all NetBSD
kernels (and most likely all OpenBSD kernels as well) have the net boot
code compiled in. See options(4) "options NFS_BOOT*". The kernel asks
the firmware what device was used for loading the kernel. If the device
is a network interface a netboot is performed, if it is a disk a disk
boot, ... It should just work automagically.
