I have a UMAX S900 without MacOS.  I'm trying to follow the System
Disk Tutorial.  It recommends that I download the Disk_Tools_PPC.img
file for the folks that do not have MacOS. I've done so and have a
file called Disk_Tools_PPC.img.bin. I've confirmed that blindly dd'ing
that onto a floppy is not going to work.  So I mumbled around and
using pkg/macutil on NetBSD/i386 was able to extract the data portion. 
That, when dd'ed onto a floppy, at least gave me a happy floppy face,
but immediately ejects that floppy and appears to want another. I tried
applying the above to SystemDisk2.3.1.smi.bin but that just gets punted
immediately from the floppy drive.

Can someone explain how I complete these first steps using a nonMac (sw/hw)
NetBSD system to derive what I need to continue following the Tutorial
so I can run the System Disk utility?

Thank you!
