A counter point: we have several hundred servers of various makes[*], siz=

and ages -- most OS versions since 4.11 right up to 7.1-p3, typically wit=
h
40+ GB HDDs for the system disk (depending on age -- the most recent mach=

have 160GB) -- all laid out in the all-in-one fashion and we've never see=

problem described. I can only suppose Lawrence ran into a specific mothe=
rboard
or BIOS limitation.
