The problem is, I could get this new machine without HDs, so the only option would be to move the RAID controller and disks over from the old server. And yes, this is P4 Xeon, so it's not the same core. (Somewhat) reduced performance is not my biggest concern. If I can bring the server up (even with reduced performance) then I can rebuild stuff as time permits. Actually, I was thinking, does the code that GCC 2.9.5 generates even make difference between CPUTYPE=p3 and CPUTYPE=p4 ? -- Toomas Aas | toomas.aas@raad.tartu.ee | http://www.raad.tartu.ee/~toomas/ * One can never know for sure what a deserted area looks like.
