You might check whether the BIOS config is set to autodetect drives at startup; in many BIOSes each IDE channel can be set to Auto/None or a specific config. Try setting all installed drives to a specific configuration, and any unused channels to None. Autodetection can sometimes take a long time. I also find that detection of cd/dvd drives is sometimes very slow...

Nope, same-oh, same-oh right down to a configuration with nothing more than a single IDE drive and a video card. The diagnosis of 2GB memory is immediate and then the thing just sits for a minute or more before finally showing the configuration (attached drives, etc.) --Chuck
