USB keyboard and 5.3RC1

[Joshua Lewis]

I have been trying to install 5.3 since it went into BETA and now I am
trying to install from the RC1 CD. My problem is when the thing is done
booting into the systand install screen my USB keyboard is
non-responsive. I have tried other keyboards with no luck (I don't have
PS/2 ports on this motherboard.) Is there a way to boot to a 4.10 CD
(the 4.10 CD seems to work with my USB Keyboards fine) and then swap out
the CD and install 5.3? Or is there a way to boot to a floppy and run
the install. Any thoughts?
