The statement above is  WRONG! The 'arc' firmware
reports the displaycontroller attached the 'jazz' bus
which is completely different physical address
from ISA/EISA bus.

Note for Warner Losh ... he suggested
I use the 'arc' printout to get the
physical address...NEC chose to report a
''vendor defined record' instead of using
'Arc' defined resouce records.

Oh could please check "RISCserver 2200 Service and
Technical Reference Manual" to see if display address
is listed.

Oh I was wondering did you get the Netbsd installed yet?
