The file eio.sys is known as ASUS Kernel Mode Driver for NT from ASUSTek Computer Inc. Kernel mode drivers such as eio.sys run in the kernel mode, which is an environment with exceptionally high level privileges. In the kernel mode of an operating system, the code that is being executed has complete and uninterrupted access to all the hardware components of the system. Drivers such as the ASUS Kernel Mode Driver for NT can execute any instruction it needs on the CPU without waiting, and can reference available memory address. Kernel mode drivers are used for core operating system components that include management instruments, direct memory access (DMA), plug and play device drivers, power management, input and out queries, video drivers, and crash drivers. If a kernel mode driver like eio.sys malfunctions or crashes, the whole operating system crashes, destroying all the data and information that is held in the primary hard drive.
