[ Support for Archive QIC-24 on Emulex? ]
Should be OK.  The one in my 3/260 works...

I don't have an ACB4000, but here is something you might try that
should at least let the stuipd thing be recognized by autoconfig.

Put an explicit line in your autoconfig for the device,
with "flags 1" at the end,  i.e.:

	sd0 at scsibus0 target 0 lun 0 flags 1

Also, apply this change below.  Please let me know if it works!
