Via will release its Esther processor next semester and will use the pentium M fsb pinout layout and probably will release some mini-atx or mini-itx compatible mobo, who know will serve for the pentium m too!
Hope the Via that build a compatible chipset (cheap), too!
But Ali would be our salvation, because will release this year a new series of chipsets
ALi M1685 North Bridge for the next-generation of Intel Pentium 4, Prescott and Pentium M processors in PGA or LGA packaging will be mass produced already in the second quarter of the year. ALi M1685 will support single-channel DDR and DDR2 SDRAM memory at 400, 533 and 667MHz. When coupled with M1566 I/O controller, the M1685+M1566 combination will provide 1 x16 PCI Express port for graphics and 2 x1 PCI Express slots for other add-in cards or some on-board peripherals, such as LAN controller and even 1 x4 PCI Express slot for bandwidth-hungry add-in cards.
This chipset smokes! Will use HT to connect southbridge and many features!
ALi M1691 North Bridge is projected to come out in late 2004 and is expected to be considerably faster than the previously mentioned M1685. It will feature dual-channel DDR and DDR2 (DDR-II) memory and will also be compatible with future processors from Intel, such as Prescott and Pentium M (probably, the Dothan). The M1691 is anticipated to work with M1673 South Bridge that sports High-Definition (Azalia) audio as well as some other interesting peculiarities.
One thought that I just had about present mobile Dothans is that the multiplier is downward unlocked for it to support Speedstep. Does anyone know if this feature has to be supported by special instructions at the chipset level in the i855 chipset or is it bios enabled. If it is bios enabled, then that would give us a chance at 200 fsb Dothans on i865 or i875 chipset boards.
I just found out that Upgradeware has a forum and I just posted a message over there asking if they are planning any kind of adapter so that we could run a P-M proc on our P4 boards. Here is the thread I started over there if you want to go and post, voicing your opinions on a socket adapter.
I just read a great review on the Dothan 2.0's performance at Anandtech yesterday and picked up some neat info at the end of the article. It seems that Shuttle has woken up to the possibilities of using P-M in their SFF systems and is presently designing a SFF system to use P-M procs. I just hope that they use a desktop chipset such as i865 or i875 with it, along with some good overclocking adjustments so we can truly explore the true power of these processors. They also point out in that article that Intel is also coming out with some ULV versions of Dothan clocked at 1100 and 1000 MHz. To me, that flags 200 fsb overclocks with that low multi on processor hand picked for their strength to run at ultra low voltages. The model numbers for them are 723 for the 1.0 and 733 for the 1.1 processors. This really sounds to me like an Intel version of the mobile XP's, albeit at a lot higher price.
Actually GH, Intel's s-spec finder shows P-M procs as both 478 and 479 pin procs. I believe the extra pin on the 479 pin versions are to keep them from bieng plugged into a P4 board. Here's a screenie of the P-M s-specs:
Reading the mobo manual, it fits boths version BGA e FGA
But backing to the 479 pin number history. Like the Intel cpu Xeon 603 and 604 pins interfaces. Newer 604 cpu boards accept the 603 cpu old version.
Checking with a zoom in the manual pdf pics, they use a SL7EP (that is a 478 pin version) to show how to install the cpu. So I think that will works with any Pentium M processor.
Because I intend to buy an used Banias cpu, until Dothan prices drop.
That's not entirely true. To run in the small notebooks that some Pentium Ms are in, yes, they need to put out a fairly small amount of heat. But a laptop can have a very high heat output CPU- like a 3.4GHz Prescott, which is what's in my Dell.
Comments
I couldn't find any information about the pin layout... am I just blind?
You're Blind Ghoos!
Go to Mudds post here. Clicnk the link to Intel's Spec Sheet and pg 37 of the pdf has the pin out.
Oh, sorry in the Via news don't talk about the fsb layout.
Here some comments about the fsb pinout layout, Via licensed from Intel the technology.

- 128KB L2 Cache
- 26.2 Million Transistors
- 31.7 Square Millimeters Die Size
- 200MHz Banias Bus (800MHz quad-pumped) and VIA "V4" Bus

Hope the mobos factories use these chipsets to make desktop boards soon
If we got the adapters made by one of the companies.
How to get news bios versions for these standard P4 boards? The mobo companies will make? Or need some especialist to make for us?

And $275 is still absurd for a single CPU board, but it's a hell of a lot better than the ~$400 for the Radisys board.
Plus you get some overclocking options too.

I need to find out if those guys ship to the US...
In USA Aopen site already shows it as new release, so I think that will be in Newegg store soon. The price will be a suprise...
But another question is where to get these 479pin pentium M processors?
I researched in Ebay and stores, they just have the 478pin version
???? some clue?
Because the new Aopen mobo just use the 479 pin version....
S478 cpus will work in a 479 pin socket.
Wow, are they different interfaces? or the same?
They are the same interface. Intel just removed the extra pin that was originally put on them to keep them from being plugged into a P4 board.

I still don't see it for sale anywhere.
This would make a great livingroom box, small and quiet.

Last tuesday Aopen's release says that the board is now shipping, but will cost $270 ( MSRP)
Of course, when hit the final consumer market will reduce a little this price like all products.
But I think that will cost about U$230 for us... (I could buy a MSI K8T Master2-FAR dual Opteron mobo instead)

I think that only sell in Japan at moment.
But the price will be same Aopen mobo. :bawling:
