How to Install Mac OS 8 (D11E4):
Last revision 6/13/96 

Please read these instructions carefully before installing
Mac OS 8.

Warning: This is a Pre-Release operating system. BACK UP all
information on all drives connected to a machine on which
you plan to run Mac OS 8. You may experience disk corruption
and data loss on this release.

You currently need two machines to boot Mac OS 8: one is a
machine from the "Hardware Supported" list below, the other
is a machine capable of running the Power Macintosh
Debugger. The two machines must be connected via a serial
cable. See "Debugger Instructions" below.

Note: Before installation, place a text file called "No
Mac OS 8 Mount" on any drives that you don't want to have
mounted while in Mac OS 8.


Late-Breaking News:
-------------------
DO NOT click the "Setup" button when creating a destkop printer. Here
are the steps to create a desktop printer in D11E4:
   0) Before installing, remove any existing desktop printers
   1) Click on the LaserWriter GX icon
   ==>You'll see a few benign asserts
   2) Click on the printer of your choice
   3) Click the "Create" button
   4) When the "Setup" dialog comes up, hit CANCEL (this is the most important step).
   5) You'll have to reboot for a desktop printer to show up correctly
   6) Go print!
See the Printing release notes for more information.


Installation Instructions:
--------------------------
1) Initialize a 250MB or larger drive using Drive Setup (see "Drive Setup
Instructions" below), or another utility. We'll call this freshly
initialized drive the "Mac OS 8 volume"
2) Install (do not copy) a fresh System 7.5.x onto the
Mac OS 8 volume
3) Run the Mac OS 8 Installer script "Install Mac OS";
install onto the Mac OS 8 volume
4) Set your startup disk to be the Mac OS 8 volume
5) Put down the Caps Lock key
6) Restart
==> You should boot into Mac OS 8


Drive Setup Instructions:
-------------------------
You should be able to install Mac OS 8 on a drive initialized
by any software. We recommend using Drive Setup 2.0d5c2 which
is incluced with the D11E4 build.

1) In the Drive Setup window, select your Mac OS 8 volume.
2) Click Initialize. You get the Initialize dialog:
"Initializing will destoy all data...".
3) Click Custom Setup...in the Initialize dialog.
4) Select a Partitioning Scheme of 1 Macintosh HFS.
5) Click OK to go back to the Initialize dialog. In the
lower status field, it should say: 
"New Partitioning: 1 Macintosh HFS
Initialization Options: none"
6) Click Initialize.


Debugger Instructions:
----------------------
To run Mac OS 8, you will need a debugging machine. This can
be any Macintosh capable of running the Power Mac debugger
connected to the Mac OS 8 machine via a serial cable. It does
not have to be a PowerPC machine, any Macintosh with 7MB
free RAM (Virtual Memory is OK) is sufficient.

There is currently no reliable way to run Mac OS 8 without
the debugger at this time; however, you should be able to
boot to Finder in most cases without a debugging machine
connected.

The latest version of the Power Macintosh Debugger is 2.1d13.

The debugger should be set to Remote Host, and the Modem
port. The serial cable needs to be in the modem port on the
Mac OS 8 machine, and in either the modem or the printer
port on the debugger machine.You can tell the debugger to always
 use either the modem or the printer port by setting 
"Target Preferences" under the Edit menu. Make sure that you
aren't using the port for something else (such as a real modem,
or AppleTalk).

When the debugger comes up, it asks you "Open which
symbolics file?" You can hit cancel at this point and load
.xSYM files later. If you don't have access to .xSYM files,
you can still do assembly language debugging. To keep this dialog
from appearing, choose "General Preferences..." from the Edit 
menu and deselect "Show open dialog at startup" in the "Other"
section.

If you aren't interested in DebugStrs, you can keep the
debugger from stopping for each DebugStr by choosing "Show
Process Browser" from the Views menu. For each process where
you want to disable DebugStrs, click to deselect the "Stop on
DebugStr()" and "Stop on Debugger()" checkboxes. To keep the
debugger from ever stopping on DebugStrs for any process, go to
General Preferences under the Edit Menu. Click to deselect
the "Set stop on Debugger()/DebugStr() default" checkbox under the
"Process Control" heading.

o  To enter the Power Mac debugger during startup, hold down
   the option key on the Mac OS 8 machine while it starts up.

o To enter the Power Mac debugger while running Mac OS 8,
   type command-shift-6 on the Mac OS 8 machine.

o To enter MacsBug, type command-shift-7 on the Mac OS 8
   machine (Note: MacsBug can be found in Bleeding Edge folder,
   D11E1:D11E1 MacsBug).

o To force an NMI (non-maskable interrupt) into the Kernel,
   type command-<Power Key> on the Mac OS 8 machine.

o  To reboot your Mac OS 8 machine, hold down command and
   control and press the power key.


Troubleshooting:
----------------
The Screen Saver is off by default. To enable it, create a
file called "Enable Screen Saver" and place it at the root
level of your Mac OS 8 drive.

Your hard disk must be 250MB or greater. This requirement is
fixed for DR1. After DR1 we will reevaluate this limitation.

It should not matter from which volume you booted System
7.5.x when you perform the Mac OS 8 install. You may be
booted from the Mac OS 8 volume or another. Make sure you
set the startup disk to be the Mac OS 8 volume and put the
caps lock key down when booting into Mac OS 8.

Sometimes if you look at the Mac OS 8 volume just after
installing, you'll see a folder called "%GLURG%" and no "Mac
OS Folder". This is because the installer uses that
temporary name during installation. If you close and reopen
the Mac OS 8 volume's window, you should see the "Mac OS
Folder".

You do not need to choose the "Update for Mac OS 8" menu item
in Drive Setup 2.0d5c2 if you have initialized your drive with
Drive Setup 2.0d5c2.
