Nothing. In fact, in one model that comes to mind (the MicroVAX-2000 and
VAXstation-2000), whether or not the system identifies itself to the OS as a
MicroVAX or a VAXstation is by a jumper on the motherboard that disables the
framebuffer.
ISTR it also tweaks the SID (system ID) so code running on the box can
trivially query that (even a DCL script) and see what it's on (most
commonly to enforce license terms for workstation vs server user head
count, etc).
Yes, that's what I said. ;) The jumper not only disables the
framebuffer, but changes how the machine identifies itself to the OS.
