I would assume that as well. Yes it matters what steppings are mixed in terms of support but Intel DOES support a number of mixed steppings and OEMs like HP have shipped mixed stepping Proliant machines (I was on the fore-front of this issue with another platform so I know this to be fact). In fact there is some public documentation about this is you can stand Intel's search feature on their website :D! -aps ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Don't recognizing SMP...
I installed FreeBSD 7.0 on HP DL 380. As you saw this result, it is not recognized as 2 CPUs. it recognized Only one CPU... If this is a DL380 G2 you may have to enable smp by choosing either windows, solaris or linux as os from bios before you get both cpu's. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner.
