Am I right ? http://svn.freebsd.org/viewvc/base/releng/7.3/sys/i386/conf/GENERIC?revision=203736&view=markup or http://tinyurl.com/28km4fc shows that --- # To make an SMP kernel, the next two lines are needed options SMP # Symmetric MultiProcessor Kernel device apic# I/O APIC --- is part of GENERIC on 7.3, ergo you needn't recompile to enjoy multiple processing joy in all(most of) its glory.

Multicore CPU's are realistically cheap, Dual and Quad Core CPU's would run you somewhere between $50-$100 in the U.S. Now as for a Multi-Core/Multi-CPU setup, that would cost you considerably more. Especially if you want more then 2 Multi-Core CPU's. pricewatch.com is a great place to judge prices (again, in the U.S.) HTH, C- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Need to compile kernel for 2 or more processors?
Hello all. I hope this question does not sound so stupid. I am sorry in advance. I am doing my guideline of the activities I need to do to change an old 2 processors INtel 386 machine with 1GB of ram and 30GB of hard disk. The machine is working fine but after more than 10 years of working will be replaced for a new machine (could be an i3, i7, or xeon maybe). This one will be honored and will continue working as our secondary DNS. Actually is running Freebsd version 7.3 PRERELEASE . I will updated to 7.3 RELEASE. This machine has 2 physical processors and I remember that on old version of FreeBSD I have to compile the kernel so the second processor could be seen. I still do not know aht processor will be but I am looking for the strongest and cheapest combination of motherboard and processor. Anyway, I was wondering, if it is only one physycal processor with 2-4 embedded (xeon by exmaple) I guess that actually we do not have to change the kernel so all processors can be seen? Am I right ? By the way, if you can suggest based on experience the best combination on price performance of motherboard/processor to follow (not necessary the latest one) please let me know.
