PPC 8500/150 running ?Newtech? G3 processor

[Rick Thomas]

Well... the diagnostic is a trifle misleading...

You don't need a *newer* MacOS, you need an *older* Mac OS.
MacOS 9.2 won't run on the 8500.

The Apple support document at
	http://docs.info.apple.com/article.html?artnum=25114
says that the highest rev of MacOS that is compatible with the 8500 
hardware is version 9.1

Unfortunately, the MacOS 9.1 upgrade CD is not bootable.  To 
install it, you need to first install 9.0 (which *is* a bootable 
CD.)

Now... You guessed it... Apple has not made the 9.0 CD available 
for download.

But... all is not lost!

As pointed out in previous postings to this list, if all you want 
is something to get BootX started, you can go as far back as 
MacOS-7.


As noted in another Apple support document at
	http://docs.info.apple.com/article.html?artnum=8970
you can use anything from 7.5.3 and beyond on the 8500.

It just so happens that MacOS 7.5.3 is available as a *free* 
download from Apple at
	http://www.info.apple.com/support/oldersoftwarelist.html
Look on that page for
	"Macintosh/System/Older_System/System_7.5_Version_7.5.3/System_7.5.3_Info.
txt"
There are 19 separate parts, each of which is a single floppy disk 
image.  Image number "01" is the boot floppy.  I don't know if you 
will need all 19 of them. Maybe you can get by with just the first 
few in order to get something that will boot far enough to run the 
BootX extension.

You'll need to set up a small HFS (not HFS+) partition (50-100 Meg) 
to install and run MacOs 7.5.3.  Leave the rest unallocated so you 
can carve it up using the YDL partitioning tool.  Once you have 
your MacOS partition running, follow the instructions on the YDL CD 
for installing BootX.

It's not really any more complicated than installing RedHat on a 
PC, it's just *different*.

Enjoy!

Rick
