Thank you Kris, and all who took the time to respond.

I shortened it to simply: CFLAGS+= -march=athlon-4 Why? You ask? Well, in the past (late 4, and all 5.x) many (most?) builds continued to echo the MNO-CPUFEATURE that the kernel always recognised & echoed during boot (All INTEL PIII's). But it appears that MAKE & 6 have no trouble with just the CPUTYPE?= , as everything that I've built (some 100+ apps) echo: -march=athlon-4 -march=athlon-4 during the entire build. *Clearly* reinforcing your /brilliant/ and /insightful/ response. :) I LOVE 6! I must admit, I was apprehensive about upgrading any further along than I had. Things got a bit wobbly towards the end of 4 and all through 5 - for me on the 55 some servers I'm running here. But WOW! What a change. Smoothe as silk and MUCH faster. Thank you Kris, and all whom contributed to this WONDERFUL next phase/ version! I got my first copy more years ago than I care to admit. A search for "where's ELVI" in altavista turned up a copy on a campus server (we all know /which/ campus). No I wasn't a student. But it was just sitting there, and I couldn't resist. I downloaded everything and loaded it - Goodbye M$DOS; the rest was history. I was hooked. I never looked back. :) Thanks again, and to who made this possible. --Chris -- panic: kernel trap (ignored) ----------------------------------------------------------------- FreeBSD 5.4-RELEASE-p12 (SMP - 900x2) Tue Mar 7 19:37:23 PST 2006 /////////////////////////////////////////////////////////////////
