Hiya Bart, Stock C-64's have no autobooting facility except with a cartridge plugged into the expansion port. You are correct in that writing the program to EPROM would allow it to autoboot. For this to work you must incorporate the EPROM a cartridge which contains the special "CBM-80" code and program vectors at $8000. See the Commodore 64 Programmers Reference Guide for details. Stock C-128 computers do have a built in autoboot facility when booted in C-128 mode. Some C-64 cartridge devices which allow autobooting a program from disk come to mind. A CMD RAMLink will allow you to autoboot from any disk device on power-up/reset. The great thing about RAMLink is that you can load the desired program onto it's RAM-disk and boot it almost instantly. Because RAMLink is externally powered, your program will still autoboot no matter how long the computer has been powered off. SuperSnapshot includes a disk autoboot feature which works with 1541/71 drives (and I think 1581 as well.) A utility program is included to write a special boot block to the disk you want to autoboot. Every time the computer is powered-on or reset, SuperSnapshot checks the drive (device #8 only) for the special boot block. The boot block contains instructions for running the program. I've read about other cartridges which provide autoboot facility to C-64 but I've only used the ones mentioned above.
