RH Questions on my RH72 box

#1) How do I get the floppy to mount? I keep getting an error that no file
system is declared or it is invalid.

#2) How do I get Java to work in Konquerer. I have already checked the boxes
to enable it globally but I get Java errors on any site with java script
running. Same sites work fine with Netcape and with Mozilla it says I need a
plug in but every time I try to install the plug in it fails.
