Hi,

Just before I got a headache with MacsBug,

Oh, I see. Thanks! Robert-san. :)   I remember a FAQ;

"NetBSD/mac68k Frequently Asked Questions with Answers/
7. Porting and Programming"
http://www.netbsd.org/Ports/mac68k/faq/faq-7.html

I got "Slots.sit.hqx" from "NuBus_Slot_Manager" directory.

It is unbelievably easy, with just double click "Slots", I get;
sResources
Directory:
81  --------->  01  --------> 0004 0001 00FF FFD4

What we need is this?

I posted above before I received kind suggestions from Michael-san,
but my post was not delivered.

Thanks! As I wrote above, I got "Slots".

0004 0001 00FF FFD4    Need more?
(MAC address is printed as 0000C54B11F4 on this card.
Honestly, I almost don't understand what I'm doing..)

Ouch!

I think I should get a "MacsBug guidebook" written in Japanese.:)

Thanks a lot,
