B10.1.5.1 Current storage FAQs
See http://www.microsoft.com/winlogo/hardware/storage/.
B10.1.5.2 DAC support and PCI storage adapters for large-memory systems [Clarification]
SDG3:30-32]
Requirements for PCI adapters to support the PCI DAC command are defined in A1.1.6. For storage devices, at a minimum this includes adapters implemented in or designed as primary storage components -- RAID, Fibre Channel, high-speed SCSI, and so on -- for systems that support more than 4 GB of system memory.
See "Large Memory Enabled Device Driver Hardware and Software Requirements" in the Windows DDK; design guidelines are summarized at http://www.microsoft.com/hwdev/newPC/PAEdrv.htm

B10.1.5.4 Support for ATA Bus Master DMA [Clarification]
[STOR-0341; SDG3:146]
-
Required for ATA controllers.
-
Required for ATA devices, and ATAPI-based hard drives.
-
Recommended for ATAPI peripherals other than hard drives, including CD and DVD devices.
In particular, non-hard disk ATAPI devices (CD, DVD, ZIP, Orb, and magneto-optical devices, and so on) are not required to support Ultra DMA transfers. However, non-hard disk ATAPI devices often share the bus with other devices. Therefore, non-hard-disk ATAPI devices must support ATAPI-5 bus termination schemes such that a device sharing the bus can achieve the bus timing necessary to perform Ultra DMA transfers.
-
Recommended for ATAPI removable media drives.

B10.1.5.5 Media status notification [Correction]
[STOR-0342; SDG3:149]
The intent of the requirement for media status notification is for devices to support the commands of the implemented bus interface so the operating system can detect when a media event has taken place. The requirements for removable storage devices are defined in the following table; they apply either to single LUN devices or to devices that are part of a Multiple LUN device.
