I know that IBM uses Intel hardware in there machines so there might be 
a connection there with the usb memdisk boot problem.
You say it is Intel hardware - but does it have a IBM, Intel, or some 
other logo on it?  When you go into the BIOS setup, does it tell you who 
the BIOS manufacturer is?  It is usually Award, Ami, or Phoenix.  If it 
does not say, then it is probably IBM.
