if you make a filesystem on it, you can mount it with mount.

It is going to take about as long to copy netscape to a ramdisk as it
takes to start netscape from a hd.

Linux, left to itself, uses all available ram to cache the most recently
used hd pages, so you can read them back from ram when you need them. I
don't think you are going to beat the default behavior with an explicit
ramdisk setup, but you are free to try. If you can predict what the
most active pages will be better than the OS, you will get better
performance by controlling it yourself. I have done it with a mainframe
OS, with one specific app that I had a lot to do with designing, but I
haven't got that far with linux. Yet.
