FOOTNOTES [Δ]

1. Choosing USB Boot and booting with a USB flash drive plugged in makes boot procedure extremely long (1m30 just to pass the IBM splash screen). However, it ends up booting the OS in the USB drive (assuming one is indeed present).
2. Internal CD/FD means the ones in the UltraBase for X series models.
