Troubleshooting The Turbo 601
Most Commonly Asked Technical Questions
- QUESTION: When I try booting off my System 7.5 Disk Tools diskette,
it tells me that this disk will not work with this Macintosh.
What do I do to make this work?
- ANSWER: You need to build a "bootable Floppy" diskette. To do
this copy the System Folder from the System 7.5 Disk Tools diskette
to your desktop. Eject the Disk Tools diskette and insert a new
high density diskette (name this diskette ¥T601 Startup¥). Copy
the System Folder from the desktop (the one you just copied from
the System 7.5 Disk Tools diskette) to the T601 Startup diskette.
Copy the Turbo 601 System Enabler (which you will find located
on your startup hard drive in the System Folder) to the root level
of the System Folder on the T601 Startup diskette. You will now
be able to use this T601 Startup diskette as a bootable floppy
in Turbo 601 mode.
- QUESTION: What do I do if I get the system error "Floating Point
Coprocessor not installed" and then a system crash in System 7.5?
- ANSWER: 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. Non-native 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 SoftFPU (you can find information
about SoftFPU on many on-line services). 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.
- QUESTION: I upgraded from a Turbo 040 to a Turbo 601. The speed
in native applications is good, but my older applications are
running slower. Why?
- ANSWER: A Turbo 601 66 MHz emulates at approximately the speed
of a 25 MHz 68040. A Turbo 601 100 MHz emulates at approximately
the speed of a 33 MHz 68040. You need to upgrade all of your software
to the PowerPC native version, where possible, and check with
the vendor of any 3rd party hardware to verify that the hardware
is PowerPC 601 compatible in order to take full advantage of the
PowerPC 601 chip.
- QUESTION: I installed a DayStar Turbo 601 board and now some of
my existing hardware does not work properly. What should I do?
- ANSWER: Verify that your Video Board, SCSI Board, or other hardware
is PowerPC 601 compatible. Contact your hardware vendor to assure
PowerPC 601 firmware compatibility.
- QUESTION: I am not seeing much of a performance increase with
the Turbo 601 installed. What is slowing it down?
- ANSWER: Make sure you are running native software and verify that
it 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
non-native. Three of these files are CloseView, Easy Access and
World Script. These three files were probably installed during
the System 7.5 installation.
- QUESTION: I am getting Type 11 and Bus errors. What should I do
to correct this problem?
- ANSWER: Disable all 3rd party CDEVs and INITs and restart. It
may be a software conflict.
- QUESTION: I am getting a bus error on boot and the dialog box
tells me to restart with extensions off. I reboot holding down
the shift key but I get the same error? What should I do to correct
this problem?
- ANSWER: Remove all NuBus boards and disconnect any external SCSI
devices. If possible, use on-board video. If you still get the
same error, build a bootable floppy and boot off of it. If either
of these tests work then the Turbo 601 is probably working properly.
The problem is either hardware or software that is not PowerPC
601 compatible. Contact your hardware/software vendor for a compatible
upgrade. If you still get the same message, it may be a defective
board. If within 30 days of purchase contact your dealer or contact
DayStar Technical Support at 770-967-2077 for repair or replacement
of the board.
- QUESTION: Does the PowerPC 601 chip have an FPU?
- ANSWER: Native applications are written to recognize the 601's
FPU. If you are running native software you will have an FPU.
If you are running non-native software you will NOT have an FPU
because emulated software expects an 68040 FPU which is only present
when running software called SoftFPU (you can find information
about SoftFPU on many on-line services).
- QUESTION: I installed a DayStar Turbo 601 board and now it appears
that I have an INIT conflict. What should I do?
- ANSWER: If you have an INIT conflict, verify that your software
is PowerPC 601 compatible. Contact your software/hardware vendor
for a compatible upgrade. Using non-native INITs greatly reduces
system performance. If no PowerPC upgrade is available the Macintosh
can be restarted in 68030 mode. This is a feature of the Turbo
601 Control Panel.
- QUESTION: I installed a DayStar Turbo 601 board and now I get
random system errors and system crashes. Is there something wrong
with my board?
- ANSWER: Probably not. Make sure System 7.5 was installed by doing
a clean install. To do this, hold down the COMMAND - SHIFT - K
keys while doing a custom install selecting ¥System for any Macintosh¥.
For details refer to Apple's manuals.
- QUESTION: What is the latest version of DayStar software for Turbo
601?
- ANSWER: The current version of our Turbo 601 software is version
1.1. For more details read TSB 101.
- QUESTION: Norton System Info says my machine is running slower
than a Quadra 605. What benchmark software should I use?
- ANSWER: There are several technical issues regarding the Turbo
601 and the Norton System Info benchmark utility. For several
different reasons, System Info does not report reliable benchmark
information. When the emulated version of System Info is installed
on pre-upgrade non-PowerPC machines, it will not perform native-mode
tests on the PowerPC chip. Further, FPU results vary depending
upon which version of the System 7.5 math library you have installed.
Other internal problems cause Norton System Info to report less-than-real-world
performance on the CPU index. DayStar recommends testing with
the widely recognized MacBench 3.0 benchmark. MacBench 3.0, a
product of Ziff-Davis Labs is available from the Ziff-Davis site on the World Wide Web.
- QUESTION: How much of a performance gain will I see with a Turbo
601 66/100 MHz?
- ANSWER We have a performance gains chart on our Faxback System
showing stock machine, 68040 and 601 products. Ask for document
#9030. This information is also available on our World Wide Web
home page at http://www.daystar.com.
- QUESTION: Do I need system 7.5?
- ANSWER: Yes, because it is required for PowerPC 601 operation.
System 7.5 is not included with the Turbo 601. Install System
7.5 doing a clean install. To do this, hold down the COMMAND -
SHIFT - K keys while doing a custom install selecting ¥System
for any Macintosh¥.
- QUESTION: I purchased a Turbo 601 which requires System 7.5. Doesn't
System Software come with the Turbo 601?
- ANSWER: No, only the PowerCard 601, PowerPro 601 40/50 MHz and
PowerPro 601 50/66 MHz ship with System Software.
- QUESTION: Is the Turbo 601 a NuBus board?
- ANSWER: No. The Turbo 601 plugs into your PDS (processor direct
slot).
- QUESTION: Can I keep my ethernet or video board in a IIsi?
- ANSWER: No. The Turbo 601 IIsi Adapter board plugs into the PDS
of the Mac IIsi and then the Turbo 601 plugs into the only slot
on the adapter board.
- QUESTION: I have a Turbo 601 installed on a IIvx and I only get
256 colors in Turbo 601 mode. I get thousands of colors in 030
mode. Am I doing something wrong?
- ANSWER: No, you are not doing anything wrong. There is a fix for
this problem. It does require that we replace parts on the board.
To accomplish this fix, contact Tech Support via fax at 770-967-3018.
We will send you a form stating everything that you need to do
to send the board in.
- QUESTION: Is the FWB SCSI JackHammer board compatible with the
Turbo 601?
- ANSWER: Yes. The "Enable SCSI Manager 4.3" checkbox must be checked
in the Turbo 601 Contol Panel to enable the use of the JackHammer
board. Be sure to read chapter 5 of the Turbo 601 User Manual
for more information.
