If this is true, how can it be turned on? Could a bios code release from Intel to the mobo makers allow this, or do they need to manufacture new chips?

64bit capability on Prescotts

they would have to manufacture new chips.
just like on 2.53b's, there is HT, its just disabled, intel didn't enable it untill the 3.06.
prescott celerons will also have their 64bitness turned on.

No. When you hear "64-bit is already built into Prescott" it means that the Prescott core physically supports it, but it is permanently disabled until Intel feels they want to enable it. They will have to ship new, EMT64 enabled Prescotts once the time comes. Once they decide to "switch them on" they will be able to do so quite easily.
It is not just speculation that Prescotts have switched-off EMT64 either, because Dell is selling EMT64 enabled P4 workstations in their Small Business store right now.
Intel plans to release "F" series of their P4 Prescotts which will have EMT64 extensions.

They want people to keep buying non 64-bit ones now and then when the 64-bit OS and software is available, they will make the 64-bit CPUs and make more money as people upgrade to the 64-bit CPUs.

I wouldn't go for the 775 chipsets as yet. The benchmark results are still inferior, PCI express still isn't widely available, DDR2 is getting better over time.
I think that it will be the chipset that replaces the 775 that will bring us a proper performance-boost.
The 64bit technology is of course ready and available. I think Microsoft and Intel together are waiting for signs of market-saturation with the 32bit systems. They will launch their new technologies when it suits their wallets and not when it suits us.

I've been saying that from the start.
But wouldn't it be cool if they did release some..."code" or something that would allow all the prescotts on the market to run 64bit.
And dont' they sell Xeons with 64bit already? Xeon is basically a P4, so of course 64bit is already ready.

The 2.4Bs would have had HT built in, but permenantly disabled. Then, when they felt the time was right (ie they needed an ace to play against AMD
) they started enabling it. EMT64 and HTT are probably enabled/disabled at such a low level that it would be nigh impossible to enable them if disabled.

I other words they want to suck more money and toss in the phrase EMT64, which is completely useless whilst its disabled. If Xeons have EMT, then why not just sell them with another name and brand them P4, just like they did with Extreme edition, so that if you buy it today you can still use it when the time is right.......Doesnt it cost money to incoperate into a chip capabilities that are disabled and will never be enabled...?

no, it would cost much more to develop 2 seperate CPU's, one with it simply not present at all, and the other with it present, but disabled and dormant.
this way, when they feel the time is right (read, when the REAL computer world catches on to 64bits, aka when Microsoft releases a 64bit OS that is suitable in a CORPORATE environment) they can flip a switch, start pumping out emt64 chips, and get the corporations with the big bucks to buy again.

Intel is selling Nocona Xeons right now with EMT64. The Nocona is based on the Prescott core. So it would be much more expensive to produce two chips.
As suggested, they don't see a need to sell a cpu that has that technology until a mainstream os i.e. Micro$oft is ready.
All this does it help Intel in the long run. People are buying the "older" 32 bit non-enabled 64 bit chips like crazy still, so they don't have any modivation until the software is at the market.
