How to Disable Cache Shadowing on Windows Vistaby Tammy Clevenger
Users who experience the blue screen of death in Microsoft Windows Vista might receive the error message to disable caching or shadowing to repair the error. Disabling disk caching and shadowing is not performed within the Vista operating system, however. Instead, this setting is configured in the computer's BIOS. The BIOS is the small program that runs when the computer starts up. The BIOS determines the media the computer will boot from as well as several rudimentary hardware settings. Disk caching and shadowing are two of these hardware settings.
Reboot the computer.
Press the "Esc" key, the "Delete" key, the "F2" key or the "Enter" key (or the key/key combination indicated by your boot process) to open the BIOS program, when prompted. A notification will appear early in the boot process regarding which key to press to open the BIOS. Press the indicated key. The BIOS opens.
Page through the BIOS using the "Alt" + "P" keys or the "Page Down" key until you locate the disk caching and shadowing entries. Note that the key combination to page through the BIOS may differ by BIOS and by version of the BIOS. Follow the on-screen instructions to page through the BIOS program.
Highlight the "Disk Caching" option and disable this option according to the on-screen instructions.
Highlight the "Disk Shadowing" option and disable this option according to the on-screen instructions.
Press the "Esc" key and select the "Save and Reboot" option. The computer will reboot and utilize the new BIOS settings. Disk caching and disk shadowing are disabled.
