I am using an ATMega168A-PU with a 16 MHz external clock.
I was able to upload the bootloader using the ATMega168/168p board.
Do I need to manually modify the fuse bits in boards.txt to configure my microcontroller to use a 16 MHz crystal? Thanks!

By uploading the bootloader you mean "burn bootloader" from the IDE menu, with one of my configurations selected?

The 168A looks functionally equivalent to the 168/168p, so the same fuses should apply to it (0xff, 0xdd, 0xf9 for an external 16MHz clock).
