It seems that you sent this to me only, and not back to the list, so I have cc'ed it back onto the list. I am in agreement here and feel the minimun information that should be given when talking about a motherboard is the the manufacture, model, chip set used, and bus types (IE, ASUS PCI/I-P54TP4 Intel Triton chip set, PCI/ISA). The BIOS mfg can be relavent when discusion problems, as one bios may allow setup changes that others do not. As a person who deals in hardware that allows me to clearly identify the board mentally in my mind. I often find myself asking for this information as the first thing I do when I see these types of postings, so can we all save that time and try to be more complete when posting this type of information. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
