[Oberon] AosCD.ISO.zip blank screen Aha!

[Paul Reed]

OK, I now understand what's going on - I put a spare
drive onto the secondary IDE bus and the Aos CD
boots fine.

With only the CD-ROM drive on the secondary bus, the
IDE driver fails to reset (see previous trace, 
compared with working trace below) and IDE3 is not 
recognized.  Any chance of fixing this?

Note that exactly the same problem happens with
Native - I hadn't tried mounting the CD before,
but it only works if a hard drive is added to
the bus.  Presumably the same driver?

Also, the old drive is recognized twice (it IS
old, and I checked the jumpers are set correctly).
Is this also something which could be fixed?

See why Wirth built his own hardware?  :)
