Dual Processor 1

[slurpyx]

Guys... as my prev post states.. am a newbie

i installed FreeBSD 4.9 on a dual processor machince..

1) How would i know if i am using or running on dual processor?

2) By default.. does FreeBSD probes the hardware (dual processor) and then installed it? or do i have to slap a new kernel? if so.. how?

If you type "sysctl hw.ncpu", it'll tell you how many CPUs are currently configured, I believe. Otherwise, you can look at the bootup messages which are stored in "/var/run/dmesg.boot".

SMP support isn't in the generic kernel, however. You'll need to uncomment some lines in the kernel config for it, and the comments tell you which ones. As far as how to rebuild the kernel, I suggest reading the FreeBSD handbook/docs, as linked to from the FreeBSD website.

tnx dude!

is there a bin or a port.. or just an easy way to enable smp? kinda like a port or something...

You just need to uncomment 2 lines in the kernel config, and recompile it. It isn't very hard.

yeah.. ive read it.. but.. the thing is.. am a bit scared.. if my new kernel doesnt work can i rly use the old kernel? is this 100% fault free

i already did the compile and make... hmm.. it worked! its showing up 2 processor..


how do i check the process? will "top" do the trick?
