Both, the xAPIC is mostly backwards compatible. The extension of the ID field just uses bits that are reserved (and hard-wired to 0) on the older APICs. Thus, if one uses 0xFF to address all CPU's (the only real difference), then it will work on both types of APICs. > I'm not happy with my Circa 1996 dual P90 box.

The P90 breakage isn't related to any APIC changes AFAICT. Do you have any more details of the exact breakage on the P90?

It wasn't clear to me at the time whether the discussion was geared toward having both APIC and xAPIC support, or only xAPIC support. Maybe you could clear that up. I'm not happy with my Circa 1996 dual P90 box. It's not inconceivable that non-xAPIC processors might get deprecated in the rush to more than 16 CPU's, like my ASUS dual P90 box seems to have been. Also, the recent change to make SSE instructions the build default also bit me on one of my machines without SSE support. -- Terry ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Re: PIII SMP
I have 5.1-RELEASE running on a dual PIII/850 SM P6DGH; lots of APIC errors on boot, but no obvious effects. I was able to complete a complete "make buildworld ... mergemaster" cycle, plus rebuild ports (including OpenOffice) with no errors. "mptable" won't completely run, but, again, no obvious symptoms.

Excellent resource! Thanks for posting this! BTW: Since the PIII's run in slightly older motherboards, it's probably worth pointing out that a number of the Intel chipsets are known to have problems with PCI bus master arbitration when you have more than 2 PCI bus master devices in the box; the one I definitely recognized as being a problem was the NX, but I had also heard there were issues with the FX and the ServerWorks III, as well. Checking "Tom's Hardware" is probably a good idea. I didn't see this mentioned in any of the "Notes"/"Comment" sections. -- Terry ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

[EMAIL PROTECTED] wrote: dear list, buying two PIII for a dual system ... what do i have to pay attention to (besides the requirements of the M/B)? aka ... are all PIII SMP capable? thanks Make sure the stepping is identical. Some motherboards require Tualatin's to be able to run dual, others will happily run even Celeron CPU's in smp. I personally run a Dell Poweredge 1500SC motherboard with two Tualatin 1.13GHz PIII's, and Ive had no problems at all with it. I also run a MSI 649D-Pro motherboard with two PIII 1Ghz (not Tualatin) which also works great, but performance wise it's no match for the dual Tualatin. I would say Tualatin's are youre best bet, they are a little expensive but they work great in dual systems, thats what they are designed for. Just make sure your motherboard can handle Tualatins. -- R ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You want the stepping to be the same. You may not be happy with P III's. I'm not sure if the SMP code has been changed to handle only the xAPIC now, or not; there was a discussion a little while back about supporting more than 16 CPUs in a machine, which would require this change. I know that my Dual P90 machine has been unable to run -current for quite some time due to some changes that went in to the low level mp_machdep code.
