Troubleshooting the PowerPro 601:
Most Commonly Asked Technical Questions
Non-Apple Hard Drive Formatting Issues
Apple's formatting software does not offer the "blind
transfers" option so if you used their formatting software
this is not an issue. However, if you used a third party
formatting software, you should contact the manufacturer of
the software (if it is not in your manual) and inquire about
disabling "blind transfers" on your accelerated Mac.
When a Macintosh owner purchases a new (or used) hard
drive, the disk is usually already formatted. Some disks are
shipped with software included that give the user some
control over the operation of their hard drive.
The program which controls access to the hard drive is
called a disk driver. The driver is written to the disk at
the time the disk is formatted. Most users never see this
operation and many don't even know that it has to occur
before their hard drive becomes usable by their
Macintosh.
Many disk drivers allow something called "blind
transfers" which was designed to speed up the transfer of
information between the hard drive and the Macintosh.
Many third party (non Apple) formatters provide the
"blind transfers" option that can cause compatibility
problems when you upgrade your Mac. For this reason, we
recommend you disable the "blind transfers" option before
installing your Turbo 040/Value 040/PowerPro 601.
Performing a Clean System Installation (System 7.5)
using Easy Install
Clean installation renames your System Folder and
installs a new System Folder on your hard disk drive. Any
special files you've added to your System Folder remain on
your hard disk, and you can install them into your new
System Folder after you install the system software. - Shut down your computer.
- Insert the Disk Tools Disk (from System 7.5) into the
floppy disk drive.
- Turn on your computer. The Disk Tools icon appears on
your screen.
- Double-click the Disk First Aid icon and follow the
onscreen instructions. Disk First Aid checks your hard
disk drive for any problems.
- When you are finished, choose Quit from the File
menu.
- Choose Restart from the Special menu.
- Insert the Install Me First disk into a floppy disk
drive and open the disk by double-clicking on its
icon.
- Open the Installer by double-clicking its icon.
- When you see the Installer's welcome screen, click
Continue. The Easy Install Dialog box appears.
- Make sure that the Destination Disk indicated on the
screen is the one on which which you want to install
system software. If the wrong disk name appears, click
the Switch Disk button until the correct disk name
appears.
- Hold down the Shift-Command-K to start the clean
installation.
- Click the Install New System Folder button and click
OK. In the Easy Install dialog box, the install button
changes to Clean Install.
- Follow the onscreen instructions. It takes a few
minutes to complete the installation.
- When you see a message reporting that the
installation was successful, you may need to click
Restart. (You need to restart only if you installed
software onto the startup disk.)
- Run the Daystar Installer to reinstall the PowerPro
601 software. (See "Installing the PowerPro 601 software"
in Chapter 8 of the PowerPro 601 manual.)
- You may want to copy some other files (such as screen
savers or other personalized items) from the "Previous
System Folder" into the System Folder. Be sure to test
these items for compatibility by following the
instructions in the previous section, "Testing for
compatibility".

Three Year Limited Warranty
Not Enough Memory to use the System 7.5 Installer
When you try to use the Installer, you see a message that
the installer is out of memory. Usually this means that your
disk cache or RAM disk is set to high.
Quit all open application programs. Open the Memory
control panel, set your disk cache to the the lowest
possible setting, turn off your RAM disk and turn on Virtual
Memory
Not Enough Memory to install software
When you try to use the Installer, you see a message that
your computer doesn't have enough memory to install the
software. This means that your Macintosh has less RAM
(random-access memory) than is required to use System
7.5
Contact your reseller for information on purchasing
additional memory.
Not enough disk space to install the System 7.5
software
When you try to use the Installer, you see a message that
there is not enough disk space available to install the
software
Make more space available on your hard disk by removing
some files from the disk. Make backup copies of the files,
if necessary, and then drag them to the Trash and choose
Empty Trash from the Special menu.
If you are installing from floppy disks, you can also try
starting up your Macintosh using the Install Me First
disk. Using the Installer this way requires less disk
space.
Difficulty modifying the System File when trying to
install System software
When you try to use the Installer, you see a message that
the System file cannot be modified (or repeated messages
asking if it's okay to modify the System file).
If virus-protection software is turned on, turn it off by
dragging it out of the System Folder and restarting your
computer. Turn it back on after installation.
Try disabling your extensions by holding down the Shift
key while you restart the computer (If you are installing
over a network, you cannot use this solution).
Your System Folder may be protected, or the System and
the Finder files may be locked. To turn off System Folder
Protection use the General Controls panel. To see if your
System file or Finder file is locked, select the file's
icon, then open the File menu and choose Get Info. To unlock
the file, click the Locked checkbox to remove the X. Restart
your computer and make sure that the System file and Finder
file are unlocked.
A nonnative application will not install properly.
Turn off the PowerPro 601. Open the PowerPro Control
Panel and select 68040 Startup, then shutdown your Mac.
Restart your Macintosh and reinstall the software.
Overall Performance seems sluggish or an application
runs slower than it did before installing the card.
Make sure that you have disabled the Easy Access and
CloseView Control Panels and have updated your System
software to a full "Universal" version.
If the program is PowerPC native, make sure the the
PowerPro 601 was turned on during the programs installation.
Some program installers detect which processor is being used
and only install a version for that processor.
Be sure that Modern Memory Manager is turned on in the
Memory control panel.
If the program is not PowerPC native, it may run faster
if you turn off the card when you use it. Use PowerPro
Control Panel to switch to the 68040.
Decrease in computer's speed after adding a control
panel or system extension
The software may not work well with Power Macintosh
computers. To find out if your new system extension or
control panel software is the problem, hold down the Space
bar while you start up your computer. When the Extensions
Manager (Included with System 7.5) opens, turn of the
suspect file. Close the Extensions Manager to resume
startup. If the computer performs better when the software
is turned off, contact the software's manufacturer for
information or an upgrade.
Screen Refresh seems sluggish and you are using a NuBus
accelerated video card.
Many NuBus accelerated video cards require an upgrade to
their ROM chip and driver software to operate at optimal
performance with PowerPC. Consult the card's vendor to
ensure that you are using the latest version for the PowerPC
machines.
Hard disk performance seems sluggish
Make sure that your hard disks are using a formatter that
supports SCSI Manager 4.3
The computer behaves strangely or has problems starting
up with the PowerPro 601 card turned on.
It may help to clear out all of the computer's settings
(PRAM) by holding down the Command-Option-P-R keys
simultaneously while the computer is starting up. (Make sure
the Caps Lock key is not pressed.) After restarting, you
will need to run to turn on the PowerPro 601 using the
PowerPro control panel. You may need to use other control
panels to adjust your settings for the date, time monitors,
and file sharing, and you may need to reselect your printer
in the Chooser.
At startup an error informs you that the PowerPro RAM or
cache is either not installed properly or is failing
This error message should only apply to PowerPro boards
that have optional slots for memory SIMMs and a 1 MB
Level 2 cache daughtercard
Make sure the SIMMs and the cache card (if your PowerPro
Model's cache is a daughtercard) are installed. If you
continue to have this problem...
Try removing the SIMMs or the daughtercard cache,
whichever was listed in the error message. If removing the
SIMMs solves the problem, replace them with known working
modules.
I cannot boot after installing the PowerPro 601 100 MHz
Board.
The clock jumper may not be set properly. It needs to
placed on the top two pins (Pins 1 and 2) in a 25 MHz
Macintosh and on the bottom two pins (Pins 2 and 3) for 33
MHz Macintosh. The factory setting is for a 33 MHz
Macintosh. Refer to the user manual for proper
installation.
My computer says it's running at 75 MHz after installing
the PowerPro 601 100 MHz Board.
The clock jumper may not be set properly. It needs to
placed on the top two pins (Pins 1 and 2) in a 25 MHz
Macintosh and on the bottom two pins (Pins 2 and 3) for 33
MHz Macintosh. The factory setting is for a 33 MHz
Macintosh. Refer to the user manual for proper
installation.
I can't boot in PowerPro 601 mode even though the
installation is correct.
The PowerPro 601 100 MHz board cannot switch processor
modes until you shut down your Macintosh. When the computer
restarts, you may notice that your computer's startup sound
is different. The startup sounds depends on the processor
the computer uses.
Getting an Unimplemented Trap error after installing my
PowerPro 601 100 MHz.
The operating System may be corrupt or not installed
properly. Make sure System 7.5 was installed during a clean
install. To do this, hold down the COMMAND - SHIFT - K keys
while doing a custom install selecting "System for any
Macintosh".
Do I need to install the Photoshop extras that come on
the installer diskettes with PowerPro 601 board?
Photoshop extra includes native filters for improved
performance with Photoshop 2.5.1. They are not necessary for
Photoshop versions 3.0 or above, because they PowerPC native
applications.
How do I add Memory to my PowerPro 601 100 MHz
board?
The PowerPro 601 100 MHz board is not designed to hold
any RAM. It utilizes the RAM on the motherboard of the
Macintosh the PowerPro is installed into. You can only add
memory to the PowerPro 601 66 MHz/ 80 MHz with RAM expansion
slots.
What is the minimum about RAM that I need to use with
the PowerPro 601?
The PowerPro 601 Requires System 7.5 or later. When using
System 7.5 it is recommended that a minimum of 8 MB of RAM
be installed in the Macintosh.
I get a "Floating Point Coprocessor not installed" and
then a system crash in System 7.5
Clearing or (zapping) the Parameter RAM should resolve
this problem. To clear the Parameter RAM press COMMAND -
OPTION - P - R keys simultaneously during the complete
startup sequence. Once you hear the third bong or startup
sound release the pressed keys. Nonnative software will not
recognize the 601 FPU, nor will it look to the motherboard
to see if it has one. The software will use the PowerPC 601
chip's emulation, which does not emulate a 68040 FPU. You
will need to purchase the PowerPC version of SoftFPU from
John Neil and Associates. If you are still having this
problem do a clean install of System 7.5. To do this, hold
down the Command - Shift - K keys while doing a custom
install selecting "System for any Macintosh". Using System
Update 1.0 for System 7.5 replaces the math library with a
new native math library which resolves most of these
problems.
Some of my existing hardware does not work properly
after installation of the PowerPro 601.
Verify that your Video Board, SCSI Board, or other
hardware is PowerPC 601 compatible. Contact your hardware
vendor to assure PowerPC 601 firmware compatibility. Also,
remove SCSI Manager and SCSI Manager 4.3 from your
Extensions folder in your System Folder.
I am not seeing much of a performance increase with the
PowerPro 601 installed.
Make sure that you are running native software and verify
that is was installed for the PowerPC 601. Make sure your
video board is accelerated (not just compatible) for
PowerPC. Try disabling different CDEVs and INITs. Several
Control Panel Devices (CDEVs) drastically reduce PowerPC
performance, especially if they are nonnative. Three of
these files are CloseView, Easy Access and World Script.
These three files were probably installed during the System
7.5 installation.
I am getting Type 11 and Bus errors.
Disable all third party CDEVs and INITs and restart. It
may be a software conflict.
Composite SIMM Information
Apple has identified problems using composite SIMMs on
selected Macintosh Computer models. Due to the nature of
these problems, Apple Does not recommend the use of
composite SIMMs in any Macintosh computer.
Definition
A Composite SIMM is defined as a SIMM made up of banks of
many smaller DRAM devices, with additional bank-controlling
circuitry and perhaps buffers for the address and control
signals. A noncomposite SIMM, on the other hand, is
organized as a single bank of devices. As an example, a 16
MB composite SIMM would be made up of thirty-two 4-megabit
DRAM chips, along with the additional circuitry to control
the banks. Conversely, a noncomposite 16 MB SIMM would be
made up of eight 16-megabit chips only. Composite SIMMs are
made up of more commonly available and less expensive parts,
hence the attraction.
Problems
Composite SIMMs pose timing and electrical problems in
some Macintosh computers, particularly those optimized for
maximum DRAM performance, such as the Quadra 610, Macintosh
Quadra 650, Macintosh Quadra 800, and the Macintosh Quadra
900 series and all Power Macintosh computers.
Composite SIMMs have a larger number of DRAM devices than
the SIMMs Apple has tested with. The extra components result
in larger peak currents to the devices during read/write
accesses and refresh. These larger peak currents
subsequently result in added stress to the power system and
an overall increase in system noise. The increase in system
noise has caused problems on some systems such as the
Macintosh Quadra 900 and Macintosh Quadra 950.
The additional circuitry added to composite SIMMs appears
to add a slight amount of overhead to the timing of memory
accesses. The Macintosh Quadra 800 has very strict timing
guidelines (it requires 60-nanosecond DRAM), and is
particularly sensitive to this potential problem. These
problems may not occur until additional SIMMs are added (for
example, two composite SIMMs may work, but four composite
SIMMs may cause random failures or the system may not boot).
In addition, the larger physical dimensions of the composite
SIMMs may make proper installation difficult or
impossible.
May Work Under Some Conditions, But...
Composite SIMMs may work under some conditions, but users
may experience random failures such as startup failures,
system errors, or other strange crashes. The errors can vary
with different SIMMs, SIMM configurations, and vendors.
In addition, process variations in chips used in various
Macintosh computers (such as memory controllers) can mean
one CPU might act a little differently than the same model
manufactured at a different time. It's even possible to see
minute variations caused by temperature and supply
voltages.
Conclusion
Apple does not support composite SIMMs, nor does it
guarantee that they will work in any Macintosh, due to the
electrical and timing problems identified with selected
Macintosh computers. Apple recommends the use of
non-composite SIMMs because they are less likely to have
problems similar to those described in this Technical Note.
While presently expensive, it is expected that the cost of
16-megabit chip SIMMs will come down.
