Just going by what you write...BTW, what are you using as a reference?

I've used ftp://ftp.seagate.com/acrobat/reference/111-1c.pdf a lot.
Also other IDE implementations on ATMegas.



PATA-6 is sort of a kludge supported by double-writing (MSB first) to each of the address registers without any intervening access to any other register. Intel employs this sort of thing on their older 8-bit peripheral support chips.

OK - but those drives should also work on non-PATA-6 systems but with
reduced capacity - right?
