Hello all, I have a server currently running on a Pentium 4 box. Yesterday I bought an AMD 762 MPX chipset to go with two Athlon MP 2000+. The production server is running FreeBSD 5.2, a GENERIC with additional SCSI/RAID controllers trimmed off. The kernel and all of the userland + ports were built with -march=p4 flags and I am wondering if there's any way I can just plug the disk into the Athlon box without rebuilding everything with the exception of the world+kernel. FYI, the kernel is SMP-aware. How does the -march flag effect the userland programs? I am aware that only OpenSSL is capable of taking advantage of specific CPU instructions but other than that? Thank you for your time, Ihsan
