this motherboard happens to be a trenton technology ntm5600 with 2x E5540 4c/8t xeons that came with the motherboard. (all the high tech companies are in georgia these days.) i'm sure that you could plop 2 8-thread cpus in most common server motherboards with reasonable bios and have similar success. i did need to change MAXCPU to 16 and employ a bit of subterfuge, as there are no mp entries for the odd numbered threads, i needed to fake them. also, there is some plan 9 funkyness with apic ids >= 8, so starting the second 8 maches takes many seconds. > why cant it be two 8-core xeons? it could be a single 8c/16t xeon 7500 or two with ht turned off. but i've never tried the 7500-series. $2500 motherboards seem just a tad rich to me. - erik
