Lucky for you, since you won't have to transfer a floppy by audio connection... there isn't a RamFAST SCSI utility disk. It's all in the ROM on your card. Take a look at the manual (hopefully you have a Rev D card...) on Asimov:

ftp://ftp.apple.asimov.net/pub/apple_II/documentation/hardware

and look for:
