Well, that depends on what other hardware you have installed. The point
is to avoid conflicts on the bus.
Some examples. Let's say you have exactly one RQDX3, one TQK50, one
DELQA and one DHV11:
VMS$ mc sysgen
SYSGEN> CONFIG
DEVICE> uda
DEVICE> tu81
DEVICE> qna
DEVICE> dhv11
DEVICE> Exit
Device: UDA Name: PUA CSR: 772150 Vector: 154 Support: yes
Device: TU81 Name: PTA CSR: 774500 Vector: 260 Support: yes
Device: QNA Name: XQA CSR: 774440 Vector: 120 Support: yes
Device: DHV11 Name: TXA CSR: 760440* Vector: 300* Support: yes

As you can see, in this case you can leave the DVH11 at its default
setting and simply use the generic kernel.
Next example. One RQDX3 and one UC07 (MSCP), one TQK50 and one UC07
(TMSCP), two DEQNA and four DHV11:
SYSGEN> CONFIG
DEVICE> uda,2
DEVICE> tu81,2
DEVICE> qna,2
DEVICE> dhv11,4
DEVICE> Exit
Device: UDA Name: PUA CSR: 772150 Vector: 154 Support: yes
Device: TU81 Name: PTA CSR: 774500 Vector: 260 Support: yes
Device: QNA Name: XQA CSR: 774440 Vector: 120 Support: yes
Device: QNA Name: XQB CSR: 774460 Vector: 300* Support: yes
Device: UDA Name: PUB CSR: 760334* Vector: 304* Support: yes
Device: TU81 Name: PTB CSR: 760444* Vector: 310* Support: yes
Device: DHV11 Name: TXA CSR: 760500* Vector: 320* Support: yes
Device: DHV11 Name: TXB CSR: 760520* Vector: 330* Support: yes
Device: DHV11 Name: TXC CSR: 760540* Vector: 340* Support: yes
Device: DHV11 Name: TXD CSR: 760560* Vector: 350* Support: yes

In this case you _have_ to change the settings of the DHV11s. The
default CSR of 760440 would clash with the second tape controller and
the default Vector of 300 would clash with the second DEQNA.
