How does one make an SDXC memory chip serve as a start up disk?

Yes, you may use an SD or SDXC card as a startup disk as long as you have formatted it at Mac OS Extended and changed the default partition table to GUID.
About the SD and SDXC card slot
Thank you very much!
No worries, I'm happy to help.
NOTE: The SD card slot is not fast, but it does may a good emergency boot/recovery device.
Very true, and that is its intended use. Thanks for the input.
