Uh, the motherboard chipset does not "implement the instruction set", that's
what processors do.

Aha, so you're the guy ! I should have guessed. Email on the
way. Rgds

you are correct of course, p3 implements the instruction set.
OEM engineers also put other controllers (i/o, multimedia etc) into the
chipsets to lighten the load on the Intel processor, these controllers
change as more and more newer i/o technology comes online, like USB1.1,
USB2.0, USB3??, firewire,flashmemory cards etc. A2*/t2* motherboards
would support newer i/o, faster video etc the microPGA 850 processor is
way cheaper than mmc2 850 processor. microPGA packaging goes up to
1000mhz if i am not mistaken.

Nope, they put them there to provide interfaces to external devices.

Some day maybe.

So?

Uh, at 850 MHz talking about "faster video" is kind of like talking about a
"chaster prostitute".

all interfaces have controllers (processor) in them with instructions to
handle the data transfer task. ( ethernet, modem, sound, video,
parallel, serial, usb, firewire)

If you redefine "processor" to include a UART or the like maybe. The only
one of those functions that normally has anything that a computer scientist
would define as a "processor" is video, where the processors on high-end
boards are as complex as CPUs but specialized to the task. There are
ethernet boards with onboard processors that perform various tasks, but
they are not common and are seldom incorporated in typical chipsets used on
motherboards. Serial is handled by a slightly improved version of the same
UART used in the original IBM PC--only real difference is that it's now
implemented as a standard cell in a VLSI chip instead of as a standalone
chip. Modems used to have onboard processors but the trend has been away
from that, with processorless modems (aka "winmodems" or "linmodems") that
use the CPU for the functions formerly performed by the onboard processor
becoming the norm. Parallel is just a different reciever/transmitter chip,
again different in no major fashion from the one in the original IBM PC.
USB and Firewire the same, just bridging from those interfaces to PCI.
Even the disk interface normally has no processor--there _is_ a separate
processor involved, but it's on the disk itself, not the motherboard.

For each of these functions there are boards with onboard processors to
support the function, but they are typically specialized and somewhat
expensive products such as multiport serial boards intended to be used to
connect dozens of terminals, not devices that are normally found on a PC
motherboard.

Sorry, but you seem to have been seriously misinformed about the details of
implementation of the various I/O devices on contemporary motherboards.

With respect, I dare to disagree. Actually right now I am clicking on
Thinkpad 600E (gorgeous machine!) with pII 500 MHz processor installed and
running with no problems at all.

I read many posts on newsgroups that argue that 600E mainboard can't hold
MMC-2 pIII processors because of issues with boot (217 error) and embedded
32 megs of 66MHz RAM. Well, there is a forum (look for address below) where
I found answers to all the qestions. Now my 600E boots without tiniest
errors and runs with 500 MHz without memory instability at all (the key is
to modify, with embedded CMOS editor, few bits that disabling onboard RAM).
One and only problem (or rather a tiny disadvantage) is that L2 cache is not
enabled at boot time and one has to explicitly enable it later. But there is
a tool for Windows to do that; and Linux users have a special kernel module
for enabling L2 cache (both I used).

If someone is interested, here is the source:
http://www.wimsbios.com/phpBB2/viewtopic.php?t=4046&postday=08&postorder=asc
&start=0


"Sharedoc" rules the forum, he is the first who found a solution for most
600E upgrade problems 🙂. His solutions I have tested personaly and I
simply can't tell how happy I am that my DVD movies are playing flawless on
600E at last.

And Sharedoc et al planning to hit the 1000 MHz record in 600E 🙂 (they
developed a mod -- with soldering, unfortunately -- for enabling Speedstep
processors to run at full speed...).

Apologize for my poor English skills, by the way.
