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
http:/
/www.intel.com/info/hyperthreading/
for more information including details on which processors support HT Technology.
Φ
Intel
®
Extended Memory 64 Technology (Intel
®
EM64T) requires a computer system with a processor, chipset, BIOS, operating system, device
drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS.
Performance will vary depending on your hardware and software configurations. See
http://www.intel.com/info/em64t
for more information including
details on which processors support EM64T or consult with your system vendor for more information.
Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system.
Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.
