Notes

Q1b

  • USB boot from device attached to external USB hub is very slow (likely stuck at USB 1.1 speeds), it’s best to connect the USB device directly to the port
  • USB touchscreen - TouchKit (eGalaxTouch)
    • works as an emulated USB mouse
    • works without drivers, but lacks calibration, also is not initialized all the time (probably not initialized from cold boot)

Q1

  • Unit is defective (does not turn on)
    • Southbridge seems to be burnt (has visible dark spot on the resin package)
    • Missing HDD + ZIF cable
    • RAM stick (Samsung 1 GB DDR2 SODIMM) was not inserted correctly
  • Power circuit OK (charges battery)
