===Towers:===
 +
*Replace RAM with tested memory (if we have the appropriate tested RAM)
 +
*If the computer has an Intel processor, install a hard drive with a Xubuntu image installed
 +
*If the computer has a PPC processor, install a blank hard drive
 +
===Laptops:===
 +
*Find the appropriate power supply for your laptop.  Check the bottom of the laptop for power requirements.  Ask your instructor if you can't find this.
 +
*Laptop RAM is never tested before being installed, so you can leave the RAM the computer came with for the moment
 +
*For MacBooks -- replace the HDD with an imaged one
 +
*For iBooks, MacBook Pros and other hard-to-work-on laptops, leave the HDD where it is and you'll follow directions to wipe it later
 +
*Attach keyboard/mouse, monitor, network cable, and power cord (as necessary)
 +
===iMacs:===
 +
*INTEL: HDDs are difficult to install, so you'll wipe the drive and install an operating system following the directions in this packet later.  RAM is easy to install, but it's laptop-sized memory, which we only test in systems, so it's okay to leave the pre-installed RAM where you'll test it later.
 +
*PPC: HDDs are difficult to install, so you'll wipe the drive following the directions in this packet later.  Depending on the model, RAM is easy to install.  Check the model number on iFixit.com to see which one you have.  Ask your instructor for clarification.

==Booting into OS X==
 +
There are a couple of ways to boot into OSX 10.  Apple computers tend to boot to external hard drives more reliably, but the hard drives themselves are not as reliable as the network.  As of writing this, Photobooth is not available on network boots, so if you are working on a computer with a built-in camera, you should boot to an external drive to test the camera.

 +
'''From Network:'''
 +
* Connect ethernet cable from the wall to the system
 +
* Hold down the ''N'' key on the keyboard while the system starts up to enter the network boot screen.
 +
 
 +
'''From External HDD:'''
 +
* Connect the OS X 10.5 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 (OS X Testing HDD) from the Startup Manager to boot into OS X
 +
* If a warning box appears while you are logging in, just click "ignore"

===Install components for triage===
 
−
*If working on a standard desktop system:
 
−
**Install a tested/wiped HDD
 
−
**Install tested RAM in each available memory slot
 
−
**Install a tested battery
 
−
*If working on a system with a built-in display:
 
−
**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 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.

===Set the system clock and NVRAM in Open Firmware===
 
−
While starting up, hold the '''Option+Apple+o+f''' keys.  Release the keys when the Open Firmware prompt comes up.  In order to set the system clock in open firmware, you need to run a set of commands Open Firmware understands.  The command you will be running uses the following syntax:
 
−
*<code>decimal dev rtc [seconds minutes hour day month year] set-time</code>
 
−
All values aside from the year should be two-digit numbers in 24-hour format.  The year should be a four-digit number.  Additionally, the clock needs to be set to UTC, so remember to add 7 hours to the current time if on regular time or 8 hours during Daylight Saving Time.  For example, to set the clock to 1:58 PM on September 18th, 2009, the command would be
 
−
*<code>decimal dev rtc 00 58 20 18 09 2009 set-time</code>
 
−
To reset the NVRAM type the following commands in the specified order:
 
−
*<code>reset-nvram</code>
 
−
*<code>set-defaults</code>
 
−
*<code>reset-all</code>
 
  
−
The system will reboot after the '''reset-all''' command is entered.
+
==Test the memory==
 +
This test should only be run if you were not able to install all tested memory (anything with Laptop RAM or older iMacs)
 +
*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 depending on the amount of RAM and the speed of the processor. With large amounts of RAM (over 1.0 GB) it may take up to an hour.
 +
* If any memory fails the test, replace it with good tested memory

#**<code>badblocks -wvvf -c1024 -e1 /dev/hda</code>
 
−
#* If that command fails, try
 
−
#**<code>badblocks -wvvf -c1024 -e1 /dev/sda</code>
 
−
#* It will take anywhere from 3 to 8 hours to run badblocks.
 
−
#** If there are any bad blocks we must replace the hard drive.
 
−
#** If there are no bad blocks, you can proceed with the installation. To do this type "exit" to leave the shell, select "Partition drives" from the list, choose "Guided Partitioning" when the partitioner starts and then accept the defaults and the rest of the installation will proceed automatically.

* Check to see if the splash screen has been enabled. To do this, run the following in a terminal:
 
−
**<code>cat /etc/usplash.conf</code>
 
−
** If the splash screen has been configured to work already, you should see an entry that looks like this (the numbers may be different, but the syntax will be the same):
 
−
***<code>xres=1024 yres=768</code>
 
−
** If no entry is found, one must be added. To do so, do the following:
 
−
*** If you are working on a system with a built-in display, determine the display's native resolution.
 
−
**** If you can't figure out your display's native resolution, just stick to the numbers used below
 
−
*** Run the following in a terminal to open up the config file in an editor:
 
−
****<code>sudo nano /etc/usplash.conf</code>
 
−
*** Add the appropriate resolution to the file in the following syntax:
 
−
****<code>xres=1024 yres=768</code>

** Run the following in a terminal:
 
−
***<code>sudo lshw</code>
 
−
****This runs a command called '''lshw''' (which stands for "list hardware")  The items to pay attention to are:
 
−
** Read through the output of the command and find:
 
−
***Amount of system memory
 
−
**** You should be able to find this under the '''memory''' heading in '''lshw'''.  If you installed the memory yourself, this readout should display the same amount of memory as what you installed.
 
−
**** Systems we build should have, at minimum, '''512 MB''' of RAM.  Ask your instructor to confirm that your system has the correct amount of memory installed.
 
−
***Type of optical drive
 
−
**** This can be found under the '''cdrom''' heading in '''lshw'''. 
 
−
***Presence of wireless card
 
−
**** This should be under one of the '''network''' headings.  You should look for an entry that mentions something about "Wireless interface" or "Broadcom".  If that exists, the system has a wireless card.
 
−
*This is a good time to shut down the system and install additional memory or a wireless card if they are missing. Ubuntu will not run well with 256MB of memory and will sometimes generate errors that don't occur when 512MB or more memory is installed.

Getting Started

Visual inspections

  • What kind of computer are you working on? Is it a tower, laptop, all-in-one? Does it have an Intel or PPC processor? What's the model number printed on the bottom (if you can read it, mark it on your triage checklist)?
  • Check for damage

If the case is dirty, clean it off with a rag. If the (laptop) battery looks beaten up or warped, change it with a good one.

Set Up Your Computer

SEE MACBUILD SPECS TO DETERMINE WHAT KINDS OF HARDWARE YOU SHOULD BE INSTALLING IN THE COMPUTER YOU ARE REBUILDING

Towers:

  • Replace RAM with tested memory (if we have the appropriate tested RAM)
  • If the computer has an Intel processor, install a hard drive with a Xubuntu image installed
  • If the computer has a PPC processor, install a blank hard drive

Laptops:

  • Find the appropriate power supply for your laptop. Check the bottom of the laptop for power requirements. Ask your instructor if you can't find this.
  • Laptop RAM is never tested before being installed, so you can leave the RAM the computer came with for the moment
  • For MacBooks -- replace the HDD with an imaged one
  • For iBooks, MacBook Pros and other hard-to-work-on laptops, leave the HDD where it is and you'll follow directions to wipe it later
  • Attach keyboard/mouse, monitor, network cable, and power cord (as necessary)

iMacs:

  • INTEL: HDDs are difficult to install, so you'll wipe the drive and install an operating system following the directions in this packet later. RAM is easy to install, but it's laptop-sized memory, which we only test in systems, so it's okay to leave the pre-installed RAM where you'll test it later.
  • PPC: HDDs are difficult to install, so you'll wipe the drive following the directions in this packet later. Depending on the model, RAM is easy to install. Check the model number on iFixit.com to see which one you have. Ask your instructor for clarification.

OS X Triage

Booting into OS X

There are a couple of ways to boot into OSX 10. Apple computers tend to boot to external hard drives more reliably, but the hard drives themselves are not as reliable as the network. As of writing this, Photobooth is not available on network boots, so if you are working on a computer with a built-in camera, you should boot to an external drive to test the camera.

From Network:

  • Connect ethernet cable from the wall to the system
  • Hold down the N key on the keyboard while the system starts up to enter the network boot screen.

From External HDD:

  • Connect the OS X 10.5 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 (OS X Testing HDD) from the Startup Manager to boot 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 you did not install RAM or a HDD earlier, check the amount of memory now and compare with the MacBuild Spec Sheet. You can adjust RAM by shutting the computer down and removing or adding RAM at this point. Remember that you will probably still need to test the RAM
    • 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
  • Fill out the system specs on the Keeper label if they are not already filled out

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 on the desktop, drag it into the trash.

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.

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 or any other 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), this points to GPU failure.
  • 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, consult your instructor. Occasional white pixels are OK.

Test the iSight camera (Laptop and iMac only)

  • Double click on the OS X Testing HDD icon and then double click on Applications. Double click on the Photo Booth application to open it. If you can see yourself in the Photo Booth application the camera works.

Check The Battery (laptop only)

  • Select the Coconut Battery icon from dock. Note the battery capacity (not the current charge) and remember that we will need to enter this value in the Notes portion of the printme sheet. For example: "according to Coconut Battery the battery has 67% of original capacity".

Test the memory

This test should only be run if you were not able to install all tested memory (anything with Laptop RAM or older iMacs)

  • 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 depending on the amount of RAM and the speed of the processor. With large amounts of RAM (over 1.0 GB) it may take up to an hour.
  • If any memory fails the test, replace it with good tested memory

Bless the Hard Drive

  • Open a terminal and type
sudo bless --device /dev/disk0s1 --setBoot --legacy
  • You will be prompted for your password, enter "freegeek". It will look like nothing happened, but it worked!

Next Steps

Once you have finished all of these steps, the computer is ready for a QC. Check in with your instructor to check if there is time left in the shift for you to finish this yourself.
