OT: Slow booting, was re: Booting an IBM MP 3000 S/390 System

[Josh Dersch]

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.)
