[Coco] FD ROM Images

[Mark Marlette]

Bill,

You can build what ever you want to. Learn from CF baseline, it is all there. It is complex.

The sIDE is more than capable of handling it, as long as you do it correctly.

I can tell that you don't understand the basis of operation/terminology, thus your confusion. ??? Everything is there, just put it all together and you'll be an expert.

I 'll admit that I haven't read the manual in quite sometime, nor will I be in the near future. No time...

You can't FLASH a .bin....or at least I don't because of the 5 byte header.

CF is a master... LBA is the method we talk to it. You could have a CHS master, then you will have to do something in the driver to tell it, to do CHS. All this you will need to know and figure out. Maybe your drive does both, maybe it only does one.....Don't know....Go look up the data on your drives and build the descriptors as needed. Watch the auto query bit in SuperDriver, can stomp on your HDB-DOS partition if you let it.

Good luck.

Back to development.....


Regards,

Mark

Me neither.  :-)

I assumed that and had it up to the point of having NitrOS9 on a
40M hard disk with a bunch of Floppy images for Basic as well.

I am trying to do this without the CF as I prefer real disks and in
order to have both a Master and a Slave no CF.  Right?

And again and again and again.  :-)

Maybe I'm just old fashioned but I prefer real disks.  And I am not sure
where CF stands now as far as maximum number of writes.

I thought when you use it the CF is Master?

I eventually figured that out.  I tried using bigger disks originally
and had a lot of problems until I determined what the disk size limit
was.

Well, the installing NitrOS9 doc seemed to work really well, but I am
having problems with the sIDE doc.  :-)

I do appreciate all the help.
