Will XD-capable processors cost more? XD/NX-capable chips will be sold at approximately the same or slightly higher cost compared to versions without XD bit. When will they start showing up in the HP desktops I purchase? HP is shipping: • i915 chipset desktop systems with XD disabled in F10 Setup. • i945 chipset desktop systems with XD enabled in F10 Setup. What HP commercial desktops support this technology? • dc5100 • dc7100 • dc7600 • dx5150 • dx6100 • dx7200 • bc1000 What HP workstations support this technology? • HP Workstation xw4200 • HP Workstation xw6200 • HP Workstation xw8200 If the processor is changing, is the chipset changing as well? For Intel-based systems, newer chipsets, starting with the i915 chipset, provide support for XD. Will the system board change with the processor change? Intel chipset-based HP system boards support a wide range of Intel processors. You should not have to change system boards when upgrading processors unless the new processor requires: • Power output that the current system board does not support. • A different chipset than what is on the system board. Will my current applications work with this new technology? In "Known Issues" on page 13, review the table that provides a list of applications currently known to not function properly with XD/NX. The table also lists links to Microsoft Knowledge Base articles about incompatibilities found during XD/NX testing. 19
