I don't think I have your exact supermicro board but ones I've used in
the past have had on board SCSI that had to be disabled
otherwise it would sit there for 30s thinking about why things were so
quiet on the bus.
Similarly PXE boot takes a while, but you say you've turned that off.
I don't think I got the one I was playing with down to much less than
30s ... which felt like an age even though I wasn't booting it very often.
