A500 expansion taken-need CD Rom

[Miked]

How do you get an Amiga 500 to boot off the hard drive hooked up to the expansion slot, while also using a Commodore A570 CD Rom?  Or am I in trouble?

Thanks guys.  After reading my post, I realize I wasn't all too clear.  But I got my answer

On a side note, whats the fastest CD ROM drive that should be run on an A500?  I know the A570 is a 1x drive, I would think that the computer could handle a slightly higher speed without any ill effects.
