IDE in Mega STE?

<< < (3/7) > >>

tuxie:
Ja hab ich dann bein Lesen auch rausbekommen. Was mich interessieren würde, ist der zweite IDE Anschluß ein echter zweiter oder nur für Master und Slave. Weiß das jemand? Wenn das ein echter zweiter ist, würde es mich interessieren welcher Speicherbereich da verwende worden ist.

Lukas Frank:
Soweit ich das gelesen habe ist es ein zweiter IDE Port und wird nur von HDDriver unterstützt ...

tuxie:
Der erste IDE Port wird ja ab $F00000 bis $F00039 eingeblendet und so wie ichs bei Uwe Seimet gelesen habe soll direkt dannach der zweite kommen.

Aber wie sehen dann die Register aus?

Ab $F00100 ?

Lukas Frank:
... keine Ahnung aber hat der Milan nicht auch zwei IDE Ports !

Ansonsten frage einfach Uwe Seimet der weiss das ...

Zitat aus dem "atari-forum.com" Betrag ->

 it has the following features.....

* IDE Controller with two ports, one primary which is Atari compatible and bootable. The second is compatible, but not bootable. Therefore providing 4 IDE devices.
* TOS 2.06 address decoder, with external pins for ROM's (or ROM upgrade board)
* Primary & Secondary ports are switchable.
Consider this, you boot from your primary drive, but it becomes corrupt. You flick a switch to your backup drive on the second port, and now it becomes the primary port and kazam your back in business.
* Possibility to stack the board, therefore offering upto 8 IDE devices (still testing this one)
* HDDriver support for both primary & secondary ports. (Already talked to Uwe about supporting, and he's currently giving me some beta versions for test).
* Possibility to go into the STE - currently with adapter - shown. Later it's possible to switch out the 68000 DIP socket for this directly. (Just tested with STE motherboard I got from Chandler :D )
* Finally, it's all done with Logic chips. A challenge I set myself to fiddle with stuff 8) . Therefore easily solderable for those who have the skills, and no programmable chips are involved, obviously if it's just the bare board.
