Windows XP SP2 is available on CD and can be downloaded from the Microsoft website. IT departments have already been advised to test application software compatibility before deploying SP2, but it has emerged that the upgrade could also cause some PC hardware to fail.
Microsoft has set up a page on its website which lists the PC manufacturers providing information on the SP2 update. At the time of writing, Microsoft listed only a handful of PC makers - IBM was notably missing.
Hewlett-Packard’s site listed 15 desktop PCs, a point of sale system and two blade servers that it had tested with SP2. It noted a number of incompatibilities, most of which could be resolved through software configuration.
IBM warned that use of the Windows firewall in XP SP2 could cause its iSeries Access for Windows functions to fail. The iSeries Access software is a client application designed to communicate with an IBM iSeries family of servers across a network.
Dell warned users of its Inspiron 9100 or XPS with the ATI Mobility Radeon 9800 video card not to install SP2. It said, "Currently the video driver loses functionality when SP2 is installed."
