 You might try some of the different operating system settings there and see if 
 they help.  I would try them all to be honest and see if any of them allow 
 the install CD to boot ok.

 Hmm, it's probably in the chipset but the manufacturer might have chosen not 
 to install any USB ports for some reason.

 The 5.2.1 install floppies don't use GENERIC but a stripped down kernel.  The 
 install CD should use GENERIC though if you boot off of the CD and don't use 
 any floppies.
