A3.R Mobile PC Client - Future Requirements
Announcement of additional future requirements will be published at http://www.microsoft.com/winlogo/hardware/system/
A4.0 Legacy-Free PC System Requirements
This section describes additional requirements or exceptions to the requirements defined earlier in Section A1.0.
A4.1 Legacy-Free PC System - Windows Compatibility A4.1.1 ACPI legacy-free support is reported as described in "ACPI Changes for Legacy Free"
[BIOS-0015; SDG3:27, 28]
http://www.microsoft.com/hwdev/onnow/download/LFreeACPI.doc
-
LEGACY_DEVICES flag is set to 0 in the ACPI FADT as defined in ACPI section 5.2.1.
-
ACPI reset mechanism as defined in ACPI section 4.7.5.
-
8042 flag is set to 0 in systems that do not include an 8042 controller; value is set to 1 in a mobile or desktop system that includes an 8042 controller.
-
Debug Port Table in the BIOS, as described in ACPI section 5.2.11.
A4.1.2 Plug and Play detection does not report the presence of Super I/O-dependent components
Based on addresses and exceptions listed in A4.1.3.
A4.1.3 No components claim to use the restricted port addresses
[BIOS-0045]
Restricted addresses:
COM = 2E8-2EF, 2F8-2FF, 3E8-3EF, 3F8-3FF
LPT = 278-27A, 378-37A, 3BC-3BE
Sound Blaster = 0220-022F
Joystick/game port = 0x200-0x20F
MPU-401 (MIDI) = 0330-0331
FDC = 3F0-3F7
Keyboard/mouse controller = 0060, 0064
The following exceptions apply:
-
An internal COM port header can be used as a debug port solution if the COM port is not exposed to the end user and does not use the I/O addresses listed in this table; these listed addresses must be claimed in the BIOS but not used. The relocated I/O address must be reported in the ACPI Debug Port table.
-
Systems that use the 8042 controller internally can use the related restricted addresses if the 8042 flag is set to 1 in the ACPI FADT. The 8042 flag must be set to 0 in systems that do not include an 8042 controller.
-
Systems can provide Super I/O-based IrDA support through the year 2001. Both desktop and mobile PCs can use the 8042 controller internally, but must not include external PS/2 connectors. Legacy-free systems that use the 8042 controller internally must set the 8042 flag to 1 in the ACPI FADT.
