Microsoft is pushing out through Windows Update a final compatibility update for Windows Vista’s ReadyBoost Feature, according to Nick White at the Vista team blog. The update will give ReadyBoost, which uses USB drives for caching to improve system performance, the ability to use 8-gigabyte and larger SD cards improves support for SDHC (Secure Digital High Capacity) and SDIO (Secure Digital Input-Output) cards and improves support for SDHC and SDIO cards.
New features that are enabled in this package
The following new features are enabled in this package:
- Support for SD High Capacity (SDHC) cards that are 8 gigabytes (GB) or larger in Windows Vista.
- Support for dual voltage (1.8-volt and 3.3-volt) Secure Digital/MultiMediaCards (SD/MMC) cards in Windows Vista.
- Support for Secure Digital Input Output (SDIO) cards in Windows Vista.
SDIO cards use an interface that adds functionality for a range of devices, such as GPS devices, Ethernet adapters, Wi-Fi or Bluetooth adapters, modems, scanners, fingerprint readers, bar-code readers, IrDA adapters, FM radio tuners, TV tuners, digital cameras, hard drives, and so on.
Note Specific hardware is required to take advantage of these new features. For example, the computer must have a supported SD Controller to use SDHC, SDIO SD, or MMC cards.

In addition to the new features that are enabled, this package fixes a problem in which the SD card may occasionally stop responding after a Windows Vista-based computer resumes from sleep (S3) or from hibernation (S4).
