Unmodified Device Driver Reuse and Improved System Dependability via Virtual Machines

The driver directly controls its device via a pass-through enhancement to the virtual machine, which permits the device driver OS (DD/OS) to access the device’s registers, ports, and receive hardware inte ...

Low Pin Count
The Low Pin Count bus, or LPC bus, is used on IBM-compatible personal computers to connect low-bandwidth devices to the CPU, such as the boot ROM, ""legacy"" I/O devices (integrated into a super I/O chip), and Trusted Platform Module (TPM). ""Legacy"" I/O devices usually include serial and parallel ports, PS/2 keyboard, PS/2 mouse, and floppy disk controller.Most PC motherboards with a LPC bus have either a Platform Controller Hub (PCH) or a southbridge chip, which acts as the host and controls the LPC bus. All other devices connected to the physical wires of the LPC bus are peripherals.
