Good morning from Michigan, USA!
A few weeks ago, I purchased an AEC-7720u to use with my ICD MIO (1mb version), and was able to have MetalGuy66 send me the ROM upgrade for it (Thank you, MG!). I ordered a new SCSI cable from Amazon last week, and started messing around with things this past weekend but then got to wondering why I was even bothering since I use my SIO2USB for pretty much everything already. So, I figured I'd sell the card and cable and get my investment back at this point.
However, while I wait to see if anyone expresses interest in it, I think I'd still like to see if I can get it up and running with the MIO, but the instructions that come with the Acard are far too simplistic for my level of understanding-- and since I never ventured into the hard drive aspects of the MIO back in the day (SCSI drives were simply too prohibitive for me back in the early 90s!!), nor did I ever have to mess with SCSI configurations when I went PC, I am turning to the pros here after not being able to track down via Search any info that seemed helpful.
So, I have the MIO and the card and what I presume is a feasible PATA IDE hard drive (I have a 4gb as well as a 13gb).
What do I do next? And didn't I read somewhere that the MIO's SCSI interface is upside-down (or was it the BBox that is upside-down)?
I presume that I'll need to provide power to BOTH the hard drive as well as the card. The instructions for the card are crazy-vague about the power terminator jumper, saying that its default is on, yet there isn't a jumper ON that connection (J2, I think, since I don't have the card near me atm).
As for the hard drive, should it be set to Single? I would presume that the answer is yes, but this is SCSI, so... uncertainty there.
In the MIO configuration, I change the drive type to SCSI, of course (right?). But then it asks me for ID, LUN and I'm lost again. I did read on an ST board elsewhere on the internet that ALL of the jumpers need to be off to get an ID of "0" when connecting to an ST. Is that the case here with the MIO, as well? And what is the LUN to be set as?
The next thing it asked was something that had 256 as the first option when I spacebar'd it. I didn't go past that because, again, I've no idea what it's for or what I need to set it as.
The next thing after that had something like a Start setting and then an End setting. I think I went with 256 as the start, and then did the end as 4096, and ended up with the size (left column) being 1mb. What do I do with either a 4gb or 13gb drive, then? Are there max limits for the Atari or MIO when it comes to these settings?
After this set of steps, do I then proceed with SpartaDOS's HDINIT? And what will it need to be told?
Lastly, rather than a mechanical drive, should I perhaps look into buying an IDE-to-CF interface instead? And if so, what should I look for in the CF (for example, capacity limits?)?
I really do apologize for what looks to me, as I re-read this, a LOT of hand-holding-- I'm hoping that this might not only help ME but also anyone else in the future who is just as unfamiliar with this aspect of 8-bitting. If this works, though, I'll obviously keep the card. But right now, it seems like such a daunting project compared to peeling and repairing mylars on 1200XLs <nervous chuckle>.
