Boot Floppy HOWTO

by Colin Wood (ender@rice.edu)

I've only tested this on '030-based Macs, but here are the steps necessary
to create a floppy with enough of the MacOS to boot any Macintosh and still
be able to boot NetBSD:

1) Obtain a copy of Apple's Network Access floppy:

ftp://ftp.info.apple.com//Apple.Support.Area/Apple.Software.Updates/US/Macintosh/Utilities/Network_Access_Disk_7.5.sea.hqx

2) Obtain a copy of the *BSD/mac68k Booter utility (I used version 1.9.6,
but I've heard from a few IIvi users that only 1.9 works on there
machines).

ftp://ftp.netbsd.org/pub/NetBSD/arch/mac68k/utils/Booter1.9.6.sit.hqx

3) Obtain a copy of MODE32 if you are going to be running on a Mac II, IIx,
IIcx, or SE/30

ftp://ftp.info.apple.com/Apple_Support_Area/Apple.Software.Updates/US/Macintosh/System/Other_System/MODE32_7.5.sea.hqx

4) Using your favorite disk image utility (Disk Copy, ShrinkWrap, etc.),
copy the image onto a high-density floppy disk.


5) Remove the "unnecessary" files from the Network Access disk:
	System Folder:Apple Menu Items:Chooser
	System Folder:Apple Menu Items:Network
	System Folder:Control Panels:Network
	System Folder:Extensions:AppleShare
	System Folder:Extensions:EtherTalk Phase 2

6) If you need MODE32, go ahead and install it onto the Network Access disk
using the MODE32 installer.

7) Take a copy of the Memory control panel from your current system and put
it in the Control Panels folder on the floppy.

8) Reboot your machine from the floppy.  When it comes up, use the Memory
control panel to make sure that your machine has 32-bit addressing turned
on.

9) Reboot your machine normally.  Insert the Network Access disk again and
remove the Finder.

10) Copy the *BSD/mac68k Booter utility into the System Folder on the
Network Access disk.  Rename the Booter to Finder.

11) Use your favorite type/creator changing utility (like ResEdit for
example) to change the Booter's type to 'FNDR' and its creator to 'MACS'.
Be sure to save your changes.

12) Close all of the windows from the floppy.  Reopen the floppy and make
sure that the System Folder has the normal System Folder icon and that the
Booter now has a Finder icon.

13) Rename to the floppy to something more useful like:  *BSD/mac68k Boot
Floppy 

14) Reboot your machine from the floppy.  It should go immediately into the
Booter.  Configure the Booter how you wish (I usually set the AutoBoot flag
in the Preferences dialog in addition to my usual settings) and choose the
Save Options & Preferences item from the File menu.  Quit the Booter (it
will immediately restart) to make sure that the prefs are saved.

15) Now you're done.  I'd suggest testing the floppy to make sure that it
works before you zap your remaining MacOS partition.
