a simple modification will make chipsets that don't recognise hyperthreading on Pentium 4s magically recognise the ground breaking technology Intel is introducing for the brains of a computer.
That will be all the more important this year as Intel readies a push to make all Pentium 4s, starting from speeds as low as 2.4GHz, hyperthreaded ready.
The only chip that currently is hyperthread enabled is the 3.06GHz and third party motherboard makers have to use new chipsets to recognise that fact.
But, we understand, there is very little difference indeed between the old lamps and the new lamps.
Intel makes the hyperthreading miracle happen by changing the state of a single pin in a Pentium 4 socket.
If that pin is left as it is, the 3.06GHz Pentium 4 will run but hyperthreading is disabled at the hardware level.
Circuit modifications may be used, however, to place that single pin in the right state which magically switches on the hyperthreading that Intel hopes to charge a cool $10 extra for, when most Pentium 4s become hyperthread enabled.
Natch, the BIOS is an important factor and has to support the HT enable/disable option in computer setup, but that appears to be about all that's required.
We understand that some enterprising third party engineers are hard at work to offer mods for folk who want hyperthreading but don't necessarily want new motherboards for old.
