Ah, the NetBSD source helped. It solved the fd-just-
doesnt-seem-to-CLAIM issue. My Power Macintosh refuses
to boot certain devices if the output-device is set to
the on-board video.
Booting NetBSD bootdisks blind works properly if output-
device is set to !screen. However, I have yet-another-
problem. I don't have a MiniDIN8 serial cable for the
Macintosh. Nor do I have a null modem.
It seems that I can generate a null modem fairly easily,
according to:
http://www.netbsd.org/Documentation/Hardware/Misc/serial.html#mac
However, I am faced with several problems:
a) I have to build my own MiniDIN8 cable
1) what wires do i use?
2) how do i get the 'connector'...?
3) how does it interface with the 'null modem'
b) I have to build my own null modem
1) see a){1,2}
c) I have zero experience with wiring and am extremely
nervous about this. I don't want to lose this Mac,
even though I bought it cheap.
1) every machine is precious
I'd love some assistance in building a serial cable from the
MiniDIN8 to a standard i86pc serial port. I'm very willing to
try things out, as long as the factors are known and I'm not
putting the hardware at a risk of shorting out, etc.
I'm sure there are peopel on this list with experience in
this area of work. I'd appreciate the help.
Don
