You need to type the full path to the directory which contains the "a" "ad" "d" etc folders in it.
Thanks heinblod. That fixed it. I needed to go one level deeper in the path to where the 'a' package was stored. Adding an additional "slackware" directory to my path solved the problem.
I figured out how to use Option # 2 ("Install from a hard drive partition") under "SOURCE MEDIA SELECTION". dmesg showed errors attempting to mount filesystem types FAT, ext2, ext3. Apparently ext4 is not supported for this function.
When I wrote the -current file structure to an ext2 formatted flash drive the setup option worked as expected.
