That's ok - it means that the kernel will run on both (i.e. less optimization). Ceri -- May the fire of my ancestors bring your last day!

Posted a reply to this a while back (check the archives). After installation you just need to recompile the kernel (see the freebsd handbook). You just need to uncomment/enable these options in the GENERIC kernel configuration like so: #cpuI486_CPU cpu I586_CPU cpu I686_CPU options SMP # Symmetric MultiProcessor Kernel options APIC_IO # Symmetric (APIC) I/O recompile and reboot: #cat /var/run/dmesg.boot | grep SMP should give you this message: SMP: AP CPU #1 Launched! If you're curious, you can run top. It will have a CPU column. -- Khairil Yusof <[EMAIL PROTECTED]> signature.asc Description: This is a digitally signed message part
Re: SMP kernel installation
Sorry after re-reading my reply one thing I did not make clear Install freebsd as you would with a uniprocessor machine, then boot that install and do what I recommend below - Mike > > You need to recompile the kernel with the SMP options turned on, install > the kernel and reboot.

Re: SMP kernel installation
You need to recompile the kernel with the SMP options turned on, install the kernel and reboot. On a reasonable modern machine takes less than 10 minutes. See /usr/src/sys/i386/conf/GENERIC and the FreeBSD Handbook. - Mike > Hi, > For a multiprocessor machine,to install FreeBSD,is > something extra needs to be done from what will be > done to install the OS for a uni processor machine?I > mean is there anything different to be installed for a > symmetric multi processor machine? > > thanks > shubha > > __ > Do You Yahoo!? > Everything you'll ever need on one web page > from News and Sport to Email and Music Charts > http://uk.my.yahoo.com > > To Unsubscribe: send mail to [EMAIL PROTECTED] > with "unsubscribe freebsd-questions" in the body of the message To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
