Boards We Like to Test

How to Test

  • Grab a Motherboard, check for visual defects (blown caps, mutilated components)
  • Secure MoBo to plate, ensuring the risers are not grounding out the board.
  • Test batery,
  • Add a processor and a fan for that processor
  • Add some memory
  • Attempt to post
    • connect the minimal things needed to post (power, keyboard, video, etc)
  • power down, then attach:
    • imaged hard drive to IDE1
    • CD Drive to IDE2
    • Floppy Drive to FD controler
    • periferials (mouse, keyboard, Video)
  • Boot into BIOS
    • change the boot order to be Floopy, harddrive
  • Boot up to Operating System
    • Check that the mouse and keyboard work
    • If you have onboard video check that it works.
    • Test all the USB ports with a mouse
    • play a audio cd, and look at a data cd
    • look at the contents of a floppy disk
    • run stress-test
  • Some cases might call for testing
    • RAID
    • SATA

So You have all the parts and a Knoppix disk.

  • First make sure everything is plugged in yeah.
 If you have never booted from a live linux cd or Knoppix now is the time to learn.
  After the system POSTs you will be met by a command prompt it will say somewhere 
  to press F2 or F3 for a cheat sheet, feel free to do so. or you could just type:
     
        knoppix 2

 then enter. That command will boot the system into run level 2
 which is short for start the system without the X server.
  • next check if the system can see all the hardware and anything else you plugged into it.
 hint: use dmesg
  • well, what if?

What if what!! It should work right RIGHT! Not all the time is right sometimes It just doesn't work. 

hint number two: check for bad capacitors. what are bad caps?? well google it or ask Dave Haskins ;)
, but most if the time if it doesn't work then it just doesn't work.

HAVE FUN
