This is the in-progress checklist for PPC desktop and laptops. Please go to the discussion pagefor the in-progress Intel instructions.

OS X Triage

Getting Started

Attach keyboard/mouse, monitor, network cable, and power cord (as necessary)


Install components for triage

Only install tested components if working on a standard desktop system (PowerMacG4 and PowerMacG5); do not install tested components on hard-to-open systems

    • Install a tested/wiped HDD
    • Install the appropriate amount of tested RAM
    • Install a tested battery
  • If working on a system with a built-in display (Laptop, iMacG4, iMacG5):
    • Install tested RAM in each available memory slot
      • NOTE: certain models (iMac G4s in particular) use SODIMMs (laptop memory) instead of/in addition to standard desktop memory. Go ahead and use untested memory for the SODIMM slot, as we'll test that memory later in the process
    • Install a tested battery if it is easily accessible (if the system uses a 3.6v battery, it can be done while installing RAM)
    • Install an AirPort/AirPort Extreme wireless card if not already present
  • If working on an oddball system (e.g. Mac mini):
    • Ask an instructor for further direction

You may need to install more parts than specifications require in order to test the system (e.g. you may need to install more RAM in a system than we'd actually need for building because we want to test all the RAM slots at once). If that's the case, remember to remove any excess components after the triage is complete.


Hardware Testing

Wipe the Hard Drive: ONLY COMPLETE THIS STEP IF YOU WERE NOT ABLE TO SWAP IN A WIPED HARD DRIVE

If it isn't easy to replace the hard drive with one that is wiped we'll need to wipe the hard drive that is in the computer. This specifically applies to all Mac laptops and iMacG5s with iSight:

  • Boot to the network by starting the computer and holding down the N key.
  • At the first boot prompt choose w (ltsp disk wiper).
  • When the computer stops at a log-in prompt, change to alternate terminal 7 by selecting the control+alt+F7 keys simultaneously. You may need to hold the FN key on laptops as well.
  • When you get the tty7 prompt, type disktest and select return. This should start the S.M.A.R.T. test.
  • Wait for confirmation of the HDD, then press enter.
  • If the drive passes the S.M.A.R.T. test it will automatically start the badblocks test which will wipe the disk. If it fails the S.M.A.R.T test it will tell you to recycle the drive.

The badblocks test usually takes 4 or more hours to run.


Reset the NVRAM

To reset the NVRAM we must first boot into Open Firmware. We do this by starting the computer and holding down the option-apple-O-F keys simultaneously. When the Open Firmware screen comes up you can type the following commands in the specified order:

  • reset-nvram
  • set-defaults
  • reset-all

The system will reboot after the reset-all command is entered.



Boot into OS X from an external FireWire HDD

  • Connect the OS X 10.4 FireWire HDD to the system
  • Connect the FireWire HDD to a power source
  • Make sure the FireWire HDD is turned on (there's a power switch on the back of the drive)
  • Hold the Option key on the keyboard while system starts up to enter the Startup Manager
  • Select the FireWire drive from the Startup Manager to boot into OS X 10.4

Log into OS X

  • If a warning box appears while you are logging in, just click "ignore"

Confirm hardware

  • Click on the System Profiler icon in the dock.
  • Check the ATA and Memory sections of System Profiler to confirm that it matches what you've added to the system so far
    • If it fails to see the HDD or reports the amount of memory incorrectly, the system may have a bad logic board and end up getting recycled. Ask an instructor for troubleshooting assistance
  • Check the Disc Burning section of System Profiler to see what the optical drive in the system can do

Test CD writing

If you determined that the optical drive in the system can write CD-RWs, do the following:

  • Erase a rewritable CD disk
    • Insert a CD-RW disk
    • Open up Disk Utility (Click on the Disk Utility icon in the dock)
    • Click on the optical drive on the left sidebar of the Disk Utility window
    • Click on the Erase tab that comes up on the right side of the window
    • Confirm that it will perform a quick erase, and click on the Erase button
    • When the erasing is complete you'll get a dialog box. Choose Open Finder from the drop down menu and click OK. This will mount the disk on the desktop.
  • Write to a blank rewritable disk
    • Select the burnme.cdr file in the left panel of Disk Utility and click the Burn button at the top of Disk Utility.
    • The disk should automatically eject when finished. If the disk icon still appears of the desktop, drag it into the trash.
    • Leave Disk Utility open for the following step.

Erase the internal hard drive so that the Mac OSX installer will recognize it

    • Select the hard drive in the left panel of Disk Utility
    • Choose the Erase tab
    • Clock on the Erase button at the lower right
    • Quit the disk Utility application

Check if WiFi works

  • Click on the AirPort icon near the upper-right corner of the screen
  • Check to see if the Freegeek wireless network shows up on the list

Disconnect the wired network, select Freegeek from the list, open up a browser, and navigate to any web page. If you see the Free Geek click-through page, it works.


Test the memory

This test should only be run if you were not able to install all tested memory (in the case of laptops and iMac g4 internal memory).

  • Open "rember" by clicking on the icon in the dock.
  • click ok, leave selected default settings, and run the test.
    • The test should take 5-30 minutes
  • If any memory fails the test, replace it with good tested memory

Stress test the cpu

  • Click on the cpu test icon in the dock
  • choose primenet as the test type and start test
    • This should take 3-10 minutes
  • If this test fails, mark the printme sheet with the test results and sell the computer as-is, or recycle it - ask your instructor

Stress test the gpu

  • Set up the screen saver for the gpu test.
    • Under the Apple menu select System Preferences > Desktops and Screen Saver
    • Scroll down to the bottom and select GPULife
    • Select Options, unclick limit framerate and click show framerate
    • Set Zoom to 1 and click OK
  • Drag your mouse arrow to the very bottom right-hand corner of the screen.
  • A black screen should come up with lots of colorful moving dots which are being generated by the gpu.
  • Look for any artifacting (obvious glitches, lines, popping lights, cross hatching). Any artifacting points to gpu failure.
  • Also check to see that the frames per second number at the bottom left-hand of the screen stays consistent.
  • If everything looks good after a minute or so, you can exit the screen by moving your mouse out of the corner.
  • If there are any gross artifacts, such as lines on the screen or a plaid screen, then note the defects on the printme sheet and sell the computer as-is or recycle it - ask your instructor. Occasional white pixels are OK.

Preparing Computer for End User

Generate "printme" report for system

  • In a terminal, type printme
  • Enter your volunteer ID in the Volunteer ID field
  • Job should be Builder
  • Type should be Apple or Apple Laptop
  • Choose whether the computer is covered or not (if it has an Uncovered Electronic Device sticker on it somewhere, it's NOT covered. If it does NOT have a Uncovered Electronic Device sticker, it's covered)
  • Choose whether the computer is an FG-PDX system or not (if it has a FG-PDX sticker, it's covered. If it does NOT have a FG-PDX sticker, it's NOT covered)
  • Notes should include the following information:
    • no OS installed
    • processor type and speed
    • Hard Drive size
    • memory size and speed
    • optical drive info
    • wireless card info
  • Print to HP LaserJet 5 (This printer is referred to as Classroom when on an Ubuntu Operating system at Free Geek) The listing for Laserjet 5 is for the build printer.

Prep system for the store

  • Clean the system and remove any stickers from the previous owner
  • Add small Free Geek sticker to the system
  • Bundle system with a power supply (if a laptop)
  • Take the system to the store or place on storage shelf as appropriate.
