Which bootloader for serial non-usb?

I have arduino-0018 and I have breadboarded an arduino using straight serial. Which bootloader do I need? I understand that some bootloaders expect to upload a driver to an ftdi usb chip.


Same bootloader supports straight serial or USB serial. The bootloader doesn't know how the serial data arrives to the chip and the Arduino IDE just allows you to select the serial port you wish to use. When using a USB serial convertor chip a driver does need to be installed in the PC's OS, not down to the FTDI chip.


Thanks, my mistake. Live and learn.
