Powering Internal and External Devices
See the specifications in Chapter 2 to determine whether the D4–470’s internal
power supply is adequate to power internal accessory devices. Use external power
only for CD–ROM drives and other external devices. The D4–470 power supply is
not designed to power external devices.
Changing the CPU
Because of the range of choices and the complexity of setup when you change
CPUs, we are unable to offer technical support or warranty coverage in the event
that a CPU change is made.
