Here is a link which describes in detail , how the UBR7223 boots with a flash and PCMCIA card.

ATA PCMCIA Flash disks use different command syntax when referring to the PCMCIA slot. Substitute the command syntax disk0: or disk1: if you are using an ATA PCMCIA Flash disk instead of slot0: or slot1: which refers to Linear PCMCIA Flash memory cards. When you see an error message such as "%Error opening slot0: (Device not ready)", try using the dir disk0: command
