	I've only ever used async targets on mesh so far. I'll try to hook
up a hard drive to it on my beige g3 when I get a chance and see if I can
make it break. I remember getting sd0 cache synchronization failed from my
ZIP drive but that thing is a hunk of junk anyway.

	I had an ATTO card that should be OFW bootable that was an esiop
board. My understanding is that Apple and Sun OpenPROM fcode is
interchangeable; which is how Apple has the LSI Fusion MPT FiberChannel
cards to power the Xraid. I don't remember any success or unsuccessful
reports to the list mail though.
