Same for me, except I've built the full 16 bit interface. I think there's
something fatally wrong with the patched ADFS when it comes to deducing
which drive is which: I reported this to Jonathan last weekend.

I gave it a go and was a bit puzzled as the investigate option spun the
floppy drive for drives 0 and 4 and resulted in 640k as the answer.

At the command line though
 *MOUNT 0  the HDD clicked but had a broken directory
 *MOUNT 1  the HDD clicked but had a broken directory
 *MOUNT 4  mounted the floppy

The report of a broken directory makes sense, since I'd not formatted it!

Indeed there is - I'll send it to you off the list,
