No dice. Nothing earlier than an enhanced //e can cold boot from anything
other than a Disk II without a PR#. That's because they only consider devices
with the firmware ID bytes of a Disk II as disk devices when doing the cold
boot slot scan. No way around that. So that means no booting directly from
3.5 disks or slinky cards or anything else either.
