BIOS Update Can Enable 64-bit Capability on Prescott Chips, Says Web-Site

A Taiwan based web-site reported a rumour claiming there is a possibility to enable 64-bit capability on Intel’s latest Pentium 4 microprocessors in LGA775 form-factor using a mainboard BIOS update. While the information may be correct, it is currently highly-unlikely that such operation will becomes popular.

“Lately there have been some rumours about some special BIOS that can ‘turn on’ the 64-bit [capability] on the [Intel Pentium 4] “Prescott” processors. I have made some enquiries and it seems that there are works in progress [that] are still in ‘alpha’ stage,” a claim over the web-site OC WorkBench states.

Intel’s Extended Memory 64 Technology also known as 64-bit Extension Technology or IA32e lets Intel’s 90nm microprocessors for desktops, workstations, 2-way and 4/8-way servers to execute specially-written 64-bit code while maintaining absolute compatibility with today’s 32-bit applications.

Previously it was believed that all Intel Pentium 4 processors “Prescott” in LGA775 packaging would sport EM64T, but Intel denied such claim. Intel said it would ship Prescott processors with 64-bit capability for 1P applications only to system integrators requesting such microprocessors for their servers and workstations. Although all Prescott CPUs, including Intel Pentium 4 and Celeron D, are 64-bit from micro-architectural standpoint, processors supplying for retail channels as well as for typical desktops have their 64-bit capability disabled.

It is unclear, how Intel suspends 64-bit capability on its chips and whether it is possible to enable it on the level of BIOS, a small program that commands computers’ mainboards.

Historically Intel disabled certain functionality on its chips in a way that it was nearly impossibly to enable it using BIOS or software tweaks. For instance, sources close to the company said virtually all Intel Pentium 4 processors at 130nm fabrication process featured Hyper-Threading technology, long before the company officially unveiled its first HT chip Intel Pentium 4 3.06GHz in late 2002. While some could enable the Hyper-Threading on various chips that did not support it officially, there were reported only a few number of such cases.

Leading workstation makers, such as HP, currently offer PCs with Intel's 64-bit Pentium 4 chips installed with Linux operating system installed. Intel is expected to officially enable EM64T on its desktop products when it releases Intel Pentium 4 processors 600-series in late February, 2005.

mấy ông thần spam ác quá .. ặc ặc ..
sang năm thì Intel nó cho con dothan ra desktop để đánh trả AMD nhưng liệu ai có tiền mua nổi con dothan/MOBO không ? hiện tại mobo cho dothan khoãng $300. AMD cũng sắp ra con mobile A64 30w để đánh con dothan trên trận chiến notebook trong nay mai. tiếp đó AMD sẽ ra tiếp con dual core để đàn áp Intel truớc khi Intel cho ra dual core.

IBM đang nghiên cúu cái tech gì quên cha rồi hình như là strain techII.. nếu thành công thì nó sẽ chạy double speed của CPU hiện tại.. anh em sẽ có con CPU 6ghz để fold.
