You use a programmer to program the ROM with the values.

A response is only as good as the question. More information allows us to offer more in response....

what ROM? Do you mean ROME perhaps? you enter data somewhere in ROME?

Its really not clear. If we dont know kind of ROM, it could be ROME.

All roads lead to Rome or isnt it?

I assume you mean PROM or EPROM or EEPROM.

ROM or Mask-ROM are usually programmed during manufacturing. PROMs are user programmable and can be programmed ONLY once. EPROMs can be programmed and then reprogram again.

Is your circuit something like this?
