Using SCSI devices
Your computer has two separate SCSI busesÑa high-speed 10 MB per second internal SCSI bus for the built-in devices like the hard disk and the CD-ROM drive and a 5 MB per second bus primarily for external devices. You can connect up to seven devices in a
to each bus.

External SCSI devices, such as scanners, hard drives, CD-ROM drives, and removable­cartridge drives can be connected to your computer through the SCSI port on the back of your computer. Note that there is also an internal SCSI cable connected to this SCSI 5 MB per second chain in case the main internal SCSI bus is completely Þlled.
Connecting a SCSI device involves four steps:
■
Setting the deviceÕs SCSI ID number
■
Ensuring proper termination
■
Connecting the device
■
Installing a software device driver (if one is required)
Setting the SCSI ID
SCSI
Each device in a SCSI chain requires a unique number called a SCSI ID, which the computer uses to identify the device. The computer itself is assigned SCSI ID 7 and the internal hard disk is assigned SCSI ID 0. Every other device you install must have a unique number from 1 to 6.
Drives provided by Power normally come with SCSI ID pre-set as follows:
SCSI ID Device
0 primary internal hard drive (terminated)
1 optional additional hard drive
3 CD-ROM drive
5 optional removable-cartridge drive
7 motherboard (self-terminated)
16
PowerTower Pro UserÕs Guide
The way you assign SCSI IDs varies from device to device. On most external devices, the ID is displayed on the back of the device. You usually change it by pressing small buttons above or below the number display. For some external and most internal devices, changing the ID requires setting switches or moving jumpers. Refer to the documentation that came with the device for exact instructions.
The important thing to remember is that each device must have an ID that is unique within its bus. If there is an ID conßict, your computer and the SCSI devices connected to it will malfunction.
Ensuring proper termination
For a SCSI chain to work properly, it must be terminated correctly. The basic rule about SCSI termination is simple: the device at the end of the chain must be termination is recommended for external SCSI chains, as it reduces noise and increases reliability. Devices located between the computer and the end of the chain must be unterminated. Devices located between the computer and the end of the chain must be unterminated.
On the internal SCSI bus, any devices you install should be unterminated because the computerÕs hard disk at the end of the bus is terminated and all of the internal connectors are in the middle of the chain.
Chapter 2, Connecting Peripheral Devices
terminated
. Active
On the external bus, you need to consider where the device is placed in the chain and whether it has an internal terminator. (Most SCSI devices use removable external terminators, but some older devices have built-in terminators that are difÞcult to remove.)
■
If you have an internally terminated device, place it at the end of the chain and remove or disable external terminators from other devices in the chain.
■
If none of the devices is internally terminated, place an external terminator on the last device in the chain and on no other device.
See the documentation that came with each device for information about how it is terminated.

Connecting an external SCSI device
The SCSI port, marked with g computer and devices such as hard disks, CD-ROM drives, scanners, printers, tape backup drives, and so on.
To connect a single SCSI device (or the Þrst device in a chain), you need a SCSI cable with a 25-pin connector on one end and a 50-pin connector on the other. For each additional external device, you need a cable with 50-pin connectors on both ends. The cables you use should be double-shielded and have approximately 110-ohm impedance. Most SCSI problems are the result of low-grade cables. Of the SCSI cables our engineers have tested, Apple and APS cables are recommended for consistent reliability. We also recommend using active termination on external chains to minimize termination problems.

Connecting an internal SCSI device
You install internal SCSI devices in one of the computerÕs internal storage bays. See ÒInstalling internal storage devicesÓ in Chapter 3 for instructions on installing internal SCSI devices.

Some SCSI devices require special software called device drivers to operate with your computer. If a device driver is required, it is normally supplied with the device; if you are unsure whether one is required, contact the manufacturer of the device. Follow the installation instructions supplied by the manufacturer. If a device driver is not supplied, you can assume that the device does not need one.

Flashing question mark on start-up
In order for your computer to start-up successfully, the computer must have a valid System Folder to start from. A ßashing question mark indicates that the computer is unable to locate a valid system folder on the hard disk or any other bootable device (i.e. a ßoppy disk, the CD-ROM, etc.). This is typically caused by lack of a bootable device, a device interfering in the boot-up process, or a corrupted System Folder.
1.
VERIFY that all external SCSI devices such as hard drives and scanners are turned on and properly conÞgured as detailed inÒUsing HDT Primer PE to test and repair SCSI disks,Ó starting on page 44.
One of the main causes of ßashing question marks is related to poorly conÞgured SCSI chains.

Isolating system software issues
If the problem your are trying to troubleshoot is not in the list in the preceding section, or if the procedures suggested there do not resolve them, you may need to use a more general troubleshooting approach outlined in this section. Most of the issues you will encounter will be caused by incompatible or corrupted software.
In order to isolate the issue, it is necessary to use a process of elimination to Þnd the single element that is the source of your issue. The method presented here is a general one designed to demonstrate the way to approach troubleshooting your computer. Though variation may need to be made in this approach for speciÞc situations, this process provides a general guideline you may follow to isolate most issues. If this process does not result in a solution to your problem, go to ÒTechnical Support Contact Information,Ó starting on page 51.

1.
REMOVE all peripherals from the back of the computer except the mouse, monitor, and keyboard.
Examples of peripheral devices include removable drives, network connections, scanners, and modems. It always easiest to test for conßicts caused by external devices Þrst. If, after removing your peripherals, your issue goes away, add back your peripherals one-at-a-time, restarting each time to verify whether or not the newly added peripheral is the source of your issue.
2.
Use the Extensions Manager to test the computer with System 7.5.x extensions only.
The Extensions Manager is located in the Control Panels folder and can be accessed via the Apple menu. You can also access the Extensions Manager during startup by holding down the Space bar as the computer boots. You can use the Extensions Manager to test the computer with only the Apple system software, excluding all non-Apple extensions and control panels which may be causing conßicts. You can do this by selecting ÒSystem 7.5.xÓ from the Sets pull-down menu. Once you select ÒSystem 7.5.xÓ you will notice that the check marks next to several items in the Extensions ManagerÕs extensions list disappear. A check mark next to an item indicates that the item is active. The items without checks marks are non-Apple system software and were disabled when you selected ÒSystem 7.5.xÓ.
3.
If after setting the computer to ÒSystem 7.5.xÓ the issue does not occur, it is most likely related to a conßicting or corrupted extension. Turn the disabled extensions on one-by-one, restarting the computer each time, and verifying that the extension you just added back is not the source of your issue.
If your issue returns after adding back an extension, disable that extension. Remove the suspect extension and try re-installing it to see if the copy on you hard drive is corrupted. If replacing the suspect extension with a fresh copy fails, contact the manufacturer of the extension to report your issue. They may have a newer version which resolves your issue.
4.
TEST the issue when booted from the Power CD.
If the issue does not occur when booted from the CD your issue may be a corrupted System Folder. If it continues to occur, the application you are trying to use may be corrupted.

Chapter 4, Troubleshooting
Starting up from the Power CD
In order to test the hard disk or reinstall system software, it is necessary to startup from the Power Computing System Software CD. There are two primary methods for booting from the Power CD:
Method 1 - The Startup Disk control panel
If the computer boots off the hard disk normally and mounts the Power CD on the desktop when it is inserted in the CD-ROM, you can boot from the Power CD using the Startup Disk control panel located in the Control Panels folder underneath the Apple menu.
When you open the Startup Disk control panel, you should see icons of all the volumes you have mounted on the desktop including the hard disk and the Power CD. The hard disk will most likely be highlighted.
1. SELECT the Power CD icon by clicking on it one time.
2. CLOSE the Startup Disk control panel.
3. SELECT Restart from the Special menu.
Tip: If the CD-ROM ejects upon restart, push it immediately back in. Otherwise, the
CD will not be present when the computer needs it for startup.
Method 2 - The Startup Key sequence
If the computer is unable to boot, or the CD-ROM is unable to mount when youÕre booted up from the hard drive, you will be unable to access the Startup Disk control panel. In these instances, you should use the startup key command sequence to boot-up from the Power CD. To do this:
1. Insert the Power Computing System Software CD into the CD-ROM player
with the artwork side of the CD facing up.

all at the same time.
Tip: There are Command, Option, and Shift keys on both the left and right sides of the
keyboard, these keys are identical in function. For the purposes of starting up from the Power CD, it is always easier to hold down the Command, Option, and Shift keys on the right-hand side of the keyboard. The Delete key is also on the right-hand side, but has no counterpart on the left. By holding all keys down on the right-hand side, only one hand is needed to hold all keys, freeing your other hand to use the mouse.
3. While continuing to hold these four keys, SELECT Restart from the
Special menu.
4. Continue holding the keys down. You will see a ßashing question mark,
then a Happy Macintosh face. RELEASE the four keys. The computer should now boot from the Power CD.
Tip: When you use the Startup key sequence to boot from the Power CD, you will
notice that hard disk does not automatically show up on the desktop when the computer is Þnished booting. This is because the startup key sequence suppresses the hard disk at startup allowing the computer to start from the Power CD. (In order to test or repair the hard disk, you must Þrst mount it by following the instructions for mounting the hard disk as detailed in ÒMounting the hard disk,Ó starting on page 45.)
Using Disk First Aid
Disk First Aid can be used as a Þrst step to Þxing minor issues on most Macintosh storage volumes such as hard disks (SCSI and IDE) and removable cartridges. Disk First Aid can be found in the Apple Utilities folder by opening the Power CD, then opening the Utilities folder, and Þnally opening the Apple Utilities folder. Double-click on Disk First Aid to launch it.
When Disk First Aid is open you will see ÒSelect volume(s) to verifyÓ at the top of the Disk First Aid window. Underneath it you will see the icons of the Power CD, your hard disk, and any other volumes mounted on the system.

Chapter 4, Troubleshooting
■ SELECT the volume you want to verify by clicking one time on its icon. Typically you
will want to verify your hard disk, but you can verify any Macintosh (HFS) volume.
Disk First Aid will then test the selected volume for directory issues. If any issues are found, they will be displayed in the ÒReview instructions and resultsÓ Þeld in the Disk First Aid window. If no issues are found, Disk First Aid will report that, ÒThe volume (your disk name) appears to be OK.Ó
If Disk First Aid does Þnd issues with this disk, you will see one of two responses:
A. ÒThe volume (your volume) needs to be repaired.Ó Ð Disk First Aid has detected minor issues on your hard disk which it can repair for you. To repair the hard disk:
1. SELECT the device you wish to repair, then
2. PRESS the ÒRepairÓ button in the lower-left-hand corner of the Disk
First Aid window.
B. ÒIssues were found but Disk First Aid could not repair them.Ó Ð The issues found were too severe to be Þxed by Disk First Aid. If you own another disk repair program, you may try using it to repair the drive. If the second disk repair program is unsuccessful, or you do not have another disk repair program, re-initialize the damaged drive using Hard Disk Toolkit as detailed in ÒRe-initializing the hard disk,Ó starting on page 46.
Using HDT Primer PE to test and repair SCSI disks
HDT Primer PE is the formatting software Power Computing includes for formatting, initializing, and testing SCSI storage devices. If your problem involves an IDE drive, go to ÒUsing Drive Setup for test and repair IDE hard disks,Ó starting on page 46.
Although most devices can be formatted by HDT Primer PE, it does not support all devices. To verify that HDT Primer PE supports your SCSI device, consult the ÒSupported DevicesÓ Þle accompanying HDT Primer in the Hard Disk Toolkit PE folder. The Hard Disk Toolkit PE folder is located in the Utilities folder on Power CD.
This section includes explanation of only the most frequently used functions of HDT Primer PE. For more detailed information on how to use HDT Primer PE, consult ÒWhat is HDT Primer PE?Ó on page 177.
44 PowerTower Pro UserÕs Guide For Technical Support, Call 1-800-708-6227
Chapter 4, Troubleshooting
When HDT Primer is launched, you will be presented with a list of SCSI devices connected to your computer. Your hard disk will most likely be the device located at ID 0. The volume name will normally be that of your hard drive. However, if the hard drive has not been mounted yet, the volume name ÒN/AÓ will appear in its place.
Mounting the hard disk
If your hard disk icon does not appear on the desktop, you can use HDT Primer PE to make it appear by mounting it. To mount a hard disk:
1. SELECT the device you wish to mount, then
2. PRESS the ÔmountÕ icon on the toolbar on the right hand side of the HDT
Primer PE window.
Testing the hard disk
If a hard disk seems to be performing unreliably, you may use HDT Primer PE to test the physical integrity of the hard disk. This test goes a step further than Disk First Aid as it tests the actual medium rather than only testing the software structures on the medium.
To test a disk:
1. SELECT the device you wish to test, then
2. PRESS the ÔtestÕ icon on the toolbar on the right hand side of the HDT
Primer PE window.
■ If the drive passes, the drive is physically Þne, but may contain software imperfections
which could be the source of your issue. RE-INITIALIZING the hard disk should erase all software on the drive, removing the corruption.
■ If the drive fails, the actual hardware of the drive is most likely damaged, CONTACT
Power Computing Technical Support for further assistance.

Re-initializing the hard disk
If the low level data on your hard disk becomes corrupted and cannot be repaired by Disk First Aid or another drive maintenance program, it may be necessary to remove all software from the hard drive to eliminate the data corruption. You can do this by re-initializing the hard disks. To re-initialize the hard disk:
CAUTION: Re-initializing the hard disk will remove all data from it. Make certain you have backed-up your Þles prior to initializing the drive.
1. SELECT the device you wish to mount, then
2. CHOOSE the ÔinitializeÕ command from the ÒFileÓ menu.
You will be presented with a warning message which states, ÒThe disk at ID x already has data on it. Initializing it will wipe out all existing data with no possibility of recovery.
3. PRESS the ÒcontinueÓ button.
A dialog box will appear which asks you to ÒChoose a partitioning methodÓ.
4. Unless you wish to partition the drive into multiple volumes, select
ÒMaximum MacintoshÓ and press the ÒOKÓ button. To partition the drive into multiple volumes see ÒPartitioning,Ó starting on page 187.
Using Drive Setup for test and repair IDE hard disks
If your computer comes with an IDE hard disk, you will not be able to use HDT Primer PE to format or test it. To format and test IDE hard drives, you should instead use AppleÕs Drive Setup application. Drive Setup can be found on the Power CD in the For Apple IDE and Apple HDs Only folder. This folder is located in the Utilities folder in the Apple Utilities folder.
When you launch Drive Setup, you will be presented with a window that lists all the connected SCSI and IDE devices. Some of these devices may appear with the name <not supported>. These devices are meant for use with HDT Primer PE or some other SCSI driver. Your IDE drive will appear on the list with the type IDE. SCSI devices will appear the type SCSI.

Easy installing system software
In most cases, you will want to do an easy install when re-installing system software. This allows the computer to determine which components are appropriate for your computer and install them for you. The easy install is the default of the system software installer.
The easy install option should appear in the upper left-hand corner of the system software installer window.
Custom installing system software
The system software installer also allows you to custom install speciÞc categories or pieces of system software without having to re-install all the system software. For example, using the custom install option, you can re-install a general class of software such as the Printing software or a speciÞc Þle such as the LaserWriter 8 driver. A custom install is most often used for replacing a speciÞc component of corrupted or missing software. For example, if the Chooser crashed with a Type -39 error every time you opened it, it would be quicker to replace only the Chooser instead of re-installing all the system software. To perform a custom install:
1. SELECT Òeasy installÓ from the upper left-hand corner of the installer
window and continue holding your mouse button.
2. You should be presented with a list of options including Òcustom installÓ.
SELECT Òcustom installÓ and release the mouse button.
Clean installing system software
A clean installation of the system software disables the existing System Folder, re-naming it ÒPrevious System FolderÓ, and create a fresh System Folder on the hard drive. A clean installation of the system software does not delete or erase any of the software on your hard drive.
To clean install:
1. Once you see the system software installer window, HOLD down the
Command, Shift, and ÔKÕ keys simultaneously.
2. This should present a dialog box asking you to ÒSelect type of
installation.Ó SELECT ÒInstall new System FolderÓ.

PRESS the ÒOKÓ button.
3.
4. The ÒInstallÓ button should now read ÒClean install.Ó
After the clean installation, you will have a new System Folder containing only the licensed Apple system software, and a Previous System Folder which contains all your old system software. Because the new System Folder contains only Apple system software, non-Apple peripherals which require their own drivers will not function until the driver is reinstalled.
5. One such peripheral is the CD-ROM drive. Power Computing computers
use the FWB CD-ROM Toolkit instead of the Apple CD-ROM extension. You must re-install the CD-ROM software after performing a clean install.
6. VERIFY that the issue has been solved. Do not add back non-Apple
system software until you are certain that all your issues were Þxed by a clean install.
7. RE-INSTALL any non-Apple system software into the new system folder
one item at time. After adding an item to the system folder, restart and verify that the issue does not return. If the issue does return, remove the software you just added and contact that softwareÕs manufacturer.
8. Once all non-Apple system software has been reinstalled into the new

The desktop Þle is an invisible Þle on your hard disk which serves as both a table-of­contents and an index for all the data on your hard drive. If are experiencing issues with proper linking to aliases or with generic or incorrect icons appearing for your Þles, rebuilding the desktop may help resolve these issues.
To rebuild the desktop:
1. OPEN the Extension Manager. The Extensions Manager is located in the
Control Panels folder and is accessible via the Apple menu.

2. SELECT ÒAll offÓ from the Sets pop-up menu. This will disable all your
extensions. To insure the desktop is rebuilt properly, it is necessary to disable all non-essential extensions and control panels to eliminate the possibility of interference.
3. LOCATE the Macintosh Easy Open control panel and turn it on. The
Macintosh Easy Open control panel writes information to the desktop Þle and will need to be active when re-building the desktop.
4. HOLD down the Command and Option keys.
5. SELECT restart from the Special menu while continuing to hold Command
and Option.
6. CONTINUE holding Command and Option as the computer restarts.
7. When the computer is Þnished starting-up you will see a dialog box which
says, ÒAre you sure you want to rebuild the desktop?Ó PRESS ÒOKÓ.
Resetting (Zapping) the PRAM
Your computer maintains settings for the various peripherals connected to it, among other things, in the PRAM (parameter read-only memory). If the information in PRAM is not properly updated, your peripherals may not function properly. Mysterious peripheral issues can often be solved by resetting the PRAM and allowing it to re-build from scratch. The process to do this is known as zapping the PRAM. To zap the PRAM:
1. HOLD down the Command, Option, ÔPÕ, and ÔRÕ keys on the keyboard
simultaneously.
2. As you continue to hold these keys, SELECT Restart from the Special
menu.

Chapter 4, Troubleshooting
Continue holding these keys. You will hear a startup chime followed a few
3.
seconds later by another startup chime. The display will also ßash on and off. After the second chime, RELEASE the keys.
The PRAM should be reset. Some of your computerÕs settings will be set to the factory default. For example, AppleTalk will be set to connect via the printer port instead of the Ethernet port. You may need to reset such preferences.

Installing expansion cards
Follow the procedure below to install expansion cards.
What you need to know about adding expansion cards
You can install PCI cards in the PCI expansion slots on your motherboard to enhance your computerÕs capabilities. For example you can add video, networking, special-purpose acceleration, or communications capabilities to your computer by adding PCI cards. The motherboard allows you to install up to six standard PCI cards, one of which is normally the high-performance video card which comes with system.

Before you install any expansion cards, be sure to follow these guidelines to protect your computer:
■
Do not remove factory-installed cards from inside the computer. Removing a card incorrectly can damage it and the computer. Contact Technical Support if you believe a factory-installed card requires repair or replacement.
60
PowerTower Pro UserÕs Guide
■
The combined power consumption of the expansion cards you install must not exceed the limits of your computer. Refer to the documentation that came with your cards for their power consumption rating and to ÒPower requirementsÓ on page 159 in this manual for the power consumption limit for your computer. PCI cards are normally limited to 15 Watts or less power consumption per card.
■
Some cards may need to be installed by an authorized service provider. Refer to the documentation that came with the card.

Adding memory
Your computerÕs random-access memory (RAM) can be increased. Memory is increased by installing or replacing memory modules The computer uses DIMMs, or dual in-line memory modules for RAM. Make sure that the memory modules you purchase are the right ones for your computer. See Appendix B, ÒTechnical Information,Ó on page 153 for technical speciÞcations.
What you need to know about adding RAM
The computer has eight DIMM slots on the motherboard, near the front of the computer, (see the following motherboard illustration).

PowerTower Pro UserÕs Guide
The DIMM slots are organized into two banks, A and B. Bank A is toward the bottom and Bank B is above it, as labeled on the motherboard. Each bank has four slots, numbered A1Ð A4 and B1Ð B4.
DIMMs can be inserted in any order, but to achieve best performance, insert DIMMs of the same capacity in corresponding slots (A1 with B1, A2 with B2, etc.), to interleave RAM memory.
All DIMMs must be 168-pin, fast-paged mode, 70-nanosecond RAM access time or faster. You can install 8 MB, 16 MB, 32 MB, 64 MB, or 128 MB DIMMs up to a total capacity of 1 GB (i.e. 1024 MB).
To increase your systemÕs RAM, install additional DIMM modules in vacant DIMM slots; if there are no vacant slots, remove one or more lower-capacity DIMMs (see ÒRemoving a DIMMÓ on page 80) and replace them with modules of higher capacity. (see ÒInserting a DIMMÓ on page 80.)
