Actually the M60 works fine with a Dothan core upgrade although no one has tested the 765 for obvious reasons. I've done enough BIOS-related programming to realized nothing is for sure.

They won't be. Intel has no desire for Prescott to be in a mobile version. Those people who incorporate desktop processors into laptops are silly in my opinion since they should make a choice. Those laptops are neither good in the mobile sense nor are they good in the desktop sense. Too much compromise on each side. That's why I bought a large Centrino "workstation" notebook (Dell M60), an ultra portable 1.99 pound laptop equipped with ULV Centrino (JVC 7310), PocketPC PDA (Ipaq 5500 series), and have one prescott equipped desktop. I use what is best for the job. Anyway, refer to my "article" here for Intel's mobile plans for the next couple months or so:

What you should care about is the 775J, it's also coming out in Q4 2004.

It is clocked at 2.13ghz, and bumps up the FSB to 533mhz.
Most current Pentium M owners *should* care because the 765 is the highest clocked processor they could upgrade to. Also, its not the 775J, but the 770 that will be the 2.13Ghz Pentium M. J stands for Excecute Disabled (NX) bit enabled Intel processors. Finally Intel CPUs will have what other architectures have had for so long.

Hrana, do you think wewould be able to use a 400 FSB Dothan with the NX bit on current 855 based lappies?

I highly doubt it because Intel says that NX bit functionality requires another BIOS upgrade and I don't think manufacturers will do that for the 400Mhz FSB Pentium M products. Its always possible, but I doubt it. Expect it with the 533Mhz FSB Pentium M. That way those manufacturers can milk us for a "new" feature.

I won't be suprised by a milk job and I know a bios update would be required, but there are going to be 400 FSB Dothans with the NX bit available. That's why I'm asking.

I will get in touch with my contact at Dell to see what they have planned. If in fact 400Mhz Dothan's come out with the NX bit, its always possible that manufacturers may decide to put them into 915 chipset boards and may totally forgo updating current 855 boards. I'll ask though, hopefully they will.

That's what I'm afraid of. I'm buying now because I want to give the 915 and PCI-E video time to mature before I jump in. Too much new in that platform to experiment on a laptop. Desktop, maybe.

I don't think the current 400MHz Dothan's are scheduled to go much past 2GHz. The 765 may have been added to fill the gap caused by delays in moving to Alviso. Most P-M chips faster than that will be for Alviso, and I don't think any current P-M notebook motherboards will support the 533MHz chips. There's not much of an upgrade path since Intel is moving to the new chipset.

Plus, any guesses on the increased performance?

That's the reason I'm currently waiting for the 533 to come out, so I know I can upgrade it in the future as and when new chips come out further down the 533 P-M line.

Thanks

wow the 2.1 ghz is more of a rip than the 2.0ghz ever was at that price pt. extra 237 bucks for 100mhz??
I got my 755 for 400 bucks and I already think thats the most I'd ever pay for a mobile cpu.

forget about the 7x5 series. it's all about the 7x0 series and the faster 533mhz bus

its hard to forget the 7x5 cpus when the 7x0 series probably requires buying a whole other notebook/motherboard to take advantage of it.

well, I'm not really sure, but I think it is a feature meant to avoid giving a process the permission to execute something from its stack (like current x86 architectures do). The reason for this is to prevent the possibility to suffer buffer overflow attacks... but, again, i'm not really sure just a conjecture...

See here:

Quote:
Execution protection (NX, or no execute) is an operating system feature that relies on processor hardware to mark memory with an attribute indicating that code should not be executed from that memory. Execution protection functions on a per-virtual memory page basis, most often leveraging a bit in the page table entry (PTE) to mark the memory page.

Execution protection prevents code execution from data pages such as the default heap, various stacks, and memory pools. Protection can be applied in both user and kernel-mode. As execution protection prevents data execution from the stack, the specific exploit leveraged by the recent MSBlaster worm would have resulted in a memory access violation and termination of the process. On a system with execution protection, MSBlaster would have been limited to a Denial-of-Service (DOS) attack, but would not have had the ability to replicate and spread to other systems. This would have significantly limited the scope and impact of the worm. And although MSBlaster in its original form may have been less malicious, it should be noted that execution protection is by no means a comprehensive defense against all viruses, worms, and other malicious code.

Oh, well, I was right, although my explanation wasn't really nice... thank you for the links!
