Embedded systems with a PC/104 bus might have a configuration that does not have ISA enabled. This creates a problem in Comedi where the PC/104 drivers cannot be enabled.

I know there are one or two PC/104-Plus CPU boards with 64-bit processors that have a PC/104 ISA bus, but I don't know how well PC/104 ISA boards work on such systems when run in 64-bit mode. Is it worth worrying about them?
If you just want the option to build-test the ISA drivers, there is a COMPILE_TEST configuration option that could be checked, e.g.:
menuconfig COMEDI_ISA_DRIVERS bool "Comedi ISA and PC/104 drivers" depends on ISA || COMPILE_TEST ---help--- Enable comedi ISA and PC/104 drivers to be built -- -=( Ian Abbott @ MEV Ltd.
