USB floppies can use CBI mode: http://www.usb.org/developers/devclass_docs/usb_msc_overview_1.2.pdf I'd guess that some firmware supports booting w/ CBI, others support booting with mass storage, and most USB floppies can support both modes (and isn't mutually exclusive, as I said in my original reply). -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
