This package installs a fix for an issue under Microsoft Windows XP on a computer with an Intel ICH5 southbridge. The driver that is used for the IDE controller may be the generic Pciide.sys driver instead of the correct Intelide.sys driver. If the computer has hot-swappable drive bays, the computer may stop responding (lock up) when you swap between two ultra DMA devices. This occurs because Pciide.sys does not support this type of swapping.
For more information about this issue, refer to Microsoft Knowledge Base article 322359, ''Intelide.sys Is Not Used on Computers with ICH4 or ICH5.''
