Hmm. The pd6729db.pdf document, page 40, says about the Ready/Busy flag
(bit 5 in Interface Status register): "..this status bit is only defined
for Memory Card Interface and is not valid in I/O Card Interface mode".
Should the code be polling this bit at all, if this is the case?
Also, bit 6 of the same register "indicates whether power to the card is
on". This bit appears to be 0 on my system with a Compact FLASH card
Well, I'll try to find the time to play with this a bit.. can't be a big
problem if someone just finds what it is.
Thanks for the datasheet pointers. I searched the intel web site for
hours, but couldn't find anything useful.
