How much would you pay for a ms> 7200rpm 4GB IDE disk? Yes, you have a point there :-). You know, it would be nice if we had a "Buying Hardware for FreeBSD" section in the handbook in which many of the points that keep coming up can be written out for new folks. EG:- Experiences with motherboards, graphics chipsets, cards controllers, disks. Beware the: frumious RZ1000. cyrix write back caching, no caching > 64MB in some mother boards motherboards w/o cache consistency support the vlb master slot problem Mach64 / sio3 port clashes et al. Advice to people setting up news servers, gateways, or personal play machines. Discussions of tradeoffs; limits run into: Eg: the MEMSIZE option to the kernel what kind of configurations are good for 10/100/1000 users when SCSI is cost effective and when IDE is good enough Tuning the OS maybe; setting up partitions for netnews (inodes mix) better NFS performance thru any magic Is anyone doing this kind of compilation already?
