Hellow. I'm a Japanese software engineer, mostly work on firmware.
(Not on UN*X. The installation was no concern with my work.)
I'd got the NetBSD from CD-ROM (included a magazine).
and I attempted to install on my Macintosh.
But It's failed at booting.
The message appeared as shown below.

"Booing... MID_M68K executable: entry 0x249e
 507356(0x0)+42720+96584+35916+37440 Bye bye..."

and also appeared the dialogue box

"This has not been tested on your machine.
 This will probably crash.
 Triple Panic : out of OREOS and Miracle Whip
 Attempting to boot anyway."
 
after I pressed on "OK".
my Macintosh was in meditation.

At first, I made partition in hard drive(external device. SyQuest 105MB)
by the APS disk tool(Imported from NASA's ftp site.).
and ran Mkfs to build filesystem, ran install Utility.
(All the filesystems I had installed.)

and then, ran the booter.
But it failed.

Please tell me what mistaken has me.
My Hardware system is

 Macintosh LC475(MPU:60LC040) with 160MB Conner HD(internal : SCSI ID 0 ).
 external HD( SyQuest 105MB : SCSI ID 6 ).
 CD-ROM Drive( TAXAN TS-CD100,Double Speed : SCSI ID 2 ).
 
Please, please help me!
