The Intel
®
 IA-32 architecture processors (e.g., Pentium
®
 4 and Pentium III processors) may contain design defects or errors
known as errata. Current characterized errata are available on request.
Hyper-Threading Technology requires a computer system with an Intel
®
 Pentium
®
 4 processor supporting Hyper-Threading
Technology and an HT Technology enabled chipset, BIOS and operating system. Performance will vary depending on the
specific hardware and software you use. See 
 for more in-
formation including details on which processors support HT Technology.
Intel
®
 Virtualization Technology requires a computer system with an enabled Intel
®
 processor, BIOS, virtual machine monitor
(VMM) and for some uses, certain platform software enabled for it. Functionality, performance or other benefits will vary de-
pending on hardware and software configurations. Intel
®
 Virtualization Technology-enabled BIOS and VMM applications are
currently in development.
Intel
®
 Extended Memory 64 Technology (Intel
®
 EM64T) requires a computer system with a processor, chipset, BIOS, OS,
device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) with-
out an Intel EM64T-enabled BIOS. 
Performance will vary depending on your hardware and software configurations. Intel
EM64T-enabled OS, BIOS, device drivers and applications may not be available. 
Check with your vendor for more
information.
