A4.2.1 “ACPI Changes for Legacy-Free PCs”
Incorporated in the current ACPI specification

A4.2.2 Debug Port Specification, V. 1.0 or later
http://www.microsoft.com/hwdev/platform/PCdesign/LR/debugspec.asp
WHQL Test Specification References:
Chapter 18, Legacy-Free Test Specification
See A1.3.
A4.3.1 - See A4.4.9 A4.3.2 - See A4.4.10 A4.4 Legacy-Free PC System - Windows Experience
Design Guideline References:

New docking stations designed for legacy-free mobile PCs must follow these requirements.
A4.4.1 No external serial, parallel, or PS/2-compatible ports and no ISA-based game ports or MPU-401 (MIDI) ports available for external connection or detected by the operating system
See A4.1.3
A4.4.2 See A2.4.1 A4.4.4 No FDC detected
To support migration away from legacy devices, floppy disk drives on legacy-free systems must be based on a solution other than an FDC. Solutions include: ATAPI floppy disk drive compliant with SFF-8070i, USB, IEEE 1394, PC Card, or SCSI-based floppy disk drives.
A4.4.5 DELETED A4.4.6 Peripherals provided with the system use non-legacy connectors and do not depend on real mode for installation or configuration
Peripherals included with the system must offer a non-legacy interface such as PCI, USB, USB 2.0, SCSI, IEEE 1394, or CardBus. Peripherals can include both a legacy interface and a non-legacy interface. Proprietary interfaces are not acceptable.
Keyboard and mouse must also use non-legacy interfaces.
A4.4.7 External input devices included with the system are HID compliant
All USB keyboards, pointing devices, game pads, and their connections included with a system must comply with the USB Device Class Definition for Human Interface Devices (HID), Version 1.1, and USB HID Usage Tables, Version 1.1. This is required whether the devices are implemented as wired or wireless.
A4.4.8 MS-DOS is not required to install or run any utilities, games, or other software provided with the system A4.4.9 No BIOS boot dependencies on ISA or other legacy devices, and no ISA-related components appear on BIOS setup screen A4.4.10 BIOS supports USB input devices at boot, and does not include hardware emulation of the 8042 controller in systems where no 8042 controller is present
