One beep usually signifies no RAM installed. Open the machine, and remove the module/s,clean and then make sure they are firmly seated and try again. If still no joy may well be high density PC modules which will not work.

PC2700 is backwards compatible with 2100. Here are the memory specs from OWC at www.macsales.com:-

At less than twenty bucks per module you can't go wrong as they are <ac specialist and have a lifetime guarantee with their modules.
