QNX4.25 Hardware Upgrade

hi all,

i am Using QNX 4.25 on Dell Optiplex 266 with IDE HD and PS2 kbd and Mouse

I Try To Install The Qnx 4.25 on Dell Optiplex 760 with SATA HD and USB mous and kbd

I Make a Partion on the Sata HD using Fsys.atapi when i Begin To Install starting With The Boot Disk The Keyboard Hangs
and This Seems Logic as The USB not Recognized In The QNX boot

Any Help in This Situation
