Thanks, Colin.

I already reported my result to "port-mac68k".
I set the video not 8 or 24 bit mode but black and white mode really.
The key point for missing to boot is that the display cannot tell the
size information to booter (or MacOS), I suspect. The multiscan 15'
display can display several size but lacks display-size-id pins to assign.
Older 13' multiscan display can show only one display size, of which
display-size-id pin #4 is connected to ground; that means MacOS can
know the display-size by sensing the id pins.
By the way, I have another questions.
Can NetBSD/mac68k boot without display?
I already work with NetBSD/mac68k-1.1 on another Macintosh.
Mac can boot without display, I tested. However, whatever I did,
I cannot boot NetBSD/mac68k without display. So I make the pulg,
that #4 pin is connected to groud, and pulg it to the display port.
I wish to know how to boot NetBSD/mac68k without display and
such a pulg.
