can´t install because usb keyboard...

[xpanic]

hello, i can´t install open server 5.0.2 or 5.0.4, the machine is a dell optiplex gx280 with only usb ports for keyboard and mouse, i had made the precraid disk for the installation(because the SATA), in "boot:" i typed:
defbootstr link=precraid
after sizing memory, the keyboard is blocked, the installation continues, but when ask´s for the precraid disk and type enter or 'q' it can´t continue because the keyboard is blocked, any suggestions?

i have tried too adding "disable=uhci" to the boot string, but does not work.

neither of these versions have a clue what usb is.
also do not use anything before 5.0.6a on a P4 or Xeon processor.

does any body have made the installation from a serial console?, i think this can help to skip the problem.
