HARDDRIVE QUERIES.(1K)

what purpose does my mighty 16mb of internal RAM serve if i install a harddrive? does it still need to be in the 1K? if so, can you switch between / use both?
p.s anyone got any info / hints / tips on harddrive install.

thanks.

this link will explain things much quicker...
