There should be an option to do so in the BIOS.
Hyperthreading has to be enabled or disabled in the BIOS.
Actually, hyperthreading is Intel's name for its implementation of simultaneous multithreading.
Hyperthreading provides high speed information processing by enabling a new set of instructions to start before the previous set finished.
In the BIOS settings, there will be an option to "enable HyperThreading". To get to the BIOS on your system, you will usually need to hit F1, F2, or Del right after you turn it on. The location to enable HyperThreading varies quite a bit, but will usually be under a menu labeled either "Advanced Settings" or "CPU Options" or something similar. Note, your CPU must support HyperThreading to be able to see this option. AMD CPUs do NOT support HyperThreading. Additionally, only select High-end or Server CPUs from Intel will support it (Core i7 and i9, or Xeon CPUs only).
No.

That depends on the chipset the motherboard uses. 865P, 850E, 845PE, 845GE, 845GV, 845E, and 845G chipsets will all work with a hyperthreading Pentium 4 (a BIOS update may be required to support hyperthreading capabilities). Older chipsets like the original 845 and 850 won't work.
Windows XP and Windows Vista, Intel's Hyperthreading did not exist before these Operating Systems. Now I may be wrong here, but I am confident that hyperthreading is a technology built into the processor itself, and any operating system should be able to utilize it. You are right to the extent that Hyper Threading is built into the processor itself, but a chipset and OS which supports hyper threading are also required. Here is the link which gives the list of OS which supports Hyperthreading http://www.intel.com/support/processors/sb/CS-017343.htm Windows XP supports HT Technology ,but widows and windows 9x/me does not
