 Please dont use this board. The fastlane is "supported", but not well
enough.

 Darn, you already have?

 I must admit, that I do not see a solution. I am a bit lost, because
you where doing very fine by trying all the things you did by removing
and replacing boards and such.

 The issue is, that your IDE-drive obviously does not release
the "grip" of the probe-routines. For SCSI I would recommend to
try the -I option. This doesnt work for IDE...

 Sorry, no (obvious|instaneous) help.
