CC3 Build pens must boot as drive A: - unfortunately most BIOSes nowadays try to boot USB mass storage devices as drive C:.
See TEC1656521 How to make a universal Community Connect 3 Workstation Build USB Flash memory pen - This tricks DOS into thinking it is booting from a floppy even if the BIOS thinks the USB pen is a 'hard disk' and normally boots as C:.
Using a similar technique, you could have all your CC3 build floppies on just one Flash pen and load any image - for example, just add to the menu.lst file for each disk image, using a menu entry such as:
You can make an image of each of your floppies (or 1.44MB Netac USB pens) using the RMPrepUSB USB->File button and save as a .IMA file.title CC3 Build disk for RM Expert 3030 and 3020 (from Hard disk UFD)
map /build1.ima (fd0)
# map the first partition of the UFD as a floppy disk
map (hd0) (hd32)
# map the UFD as a CD
map (hd1) (hd0)
# map the real hard disk as hard disk 0
# hook Int13 interrupts so all map changes take affect
# set the file root as the floppy disk
# load the io.sys code into memory from the floppy disk (now ufd is fd0)
# Tweak BIOS device numbers so DOS sees 1 floppy and 1 hd
