Explanation for technical issues :
PnP device :
Device that has Plug & Play compatibility. That means it will request for DMA,
IRQ, I/O and Memory from the PnP BIOS and all these requests can be re-
locatable. In other words, these devices do not utilize any fixed resources.
All PCI devices and all ISA PnP devices are PnP devices.
Legacy device :
A legacy device is a device that all its resources are fixed by hardware (or selected
by jumpers).
All ISA Non-PnP devices are legacy device.
Extended System Configuration Data (ESCD) :
A media between the user and the system BIOS for passing the legacy devices
information‘s. This information is stored in the onboard NVRAM (flash ROM).
