I know this is kind of a silly thing to do but I was just :wondering if it is possible. : :I tried it on my BP6, but got a "panic: NO BSP found!" or something like :that on boot. If this is indeed possible I can give it another go, and :post my mptable, dmesg, and kernel conf. : :Tom Embt :tom@embt.com It should work just fine, simply compile and run a UP kernel on it (or perhaps an SMP kernel with NCPU set to 1). A number of machines at a company I consult for run UP kernels on SMP boxes with only one cpu populated. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
