This time, two new drives showed up in the partitioner (/dev/nvme0n1 and /dev/nvme1n1), but they're both listed as unknown (their capacities, however, are displayed as 400.1 GB and 512.1 GB respectively, which technically identifies the first as the SSD and the second as the M.2 drive). Going back to section 2.5 of the mobo datasheet suggests that we should assign each device in the expansion slot an IRQ (from my understanding, an IRQ is a number from 0 to 15 that marks the priority level of the device). To do so, we have to use the BIOS menu, so I aborted the installation and pressed the 'Delete' key during the boot up to get to the BIOS menu.
But through the entire tree of menus, I was only able to find an IRQ for Serial Port 1 and Serial Port 2, under NCT6779D Super IO Configuration. Wikipedia's [https://en.wikipedia.org/wiki/Interrupt_request_(PC_architecture) article on interrupt requests] notes that, "PCI Express does not have physical interrupt lines at all, and uses MSI exclusively." So I guess IRQs are no longer a big deal (they "went the way of the dodo," as Ed says).
