some XPS or other Dell desktop model has bios option of halt on error: all but keyboard, none, all.  user can choose option to skip start up error.  however this is poorly documented in manual when it mentions bios.  for example in XPS 730 which seems to be old phoenix bios.

not sure if the latter Aptico bios prevalent in Dell is doing better.

unless you own a pc in your hand to inspect, very hard to help others by following Dell menu.

Does any XPS 8930 user see a bios option to halt on error etc?
