Windows Dual-Boot Question

I would like to know if it is possible to set up my computer so that it can dual-boot to either Windows Me or Windows 98 (1st edition). My computer is currently running Windows Me on a FAT32 system with a single partition. I would prefer to keepthe existing single partition and install Windows 98 in a separate directory called Win98 without repartitioning the hard disk into two separate partitions — is this possible? **Also does Windows 98 1st Ed. support USB 1.1 devices?
