Hi, I've just installed a fc5 machine. He needs this rev because it is compatible with his bruker software. Anyway, he already had 1 gig of memory in the machine, but when we put another bank of memory (1 gig) we could not boot up. We did a switch and they (both 1 gig dimms) and they both work apart, but not together. Has anyone ran into this problem? I guess I could look on fedoraproject.org to see if fc5 supports 2 gigs of ram. Anyway, any suggestions/advice/opinions are appreciated. Thank you in advance. Paula
