[Coco] [CoCo] Just learning OS-9 - Questions

[Luis Antoniosi (CoCoDemus)]

hi, as I said here is the rawcopy:

https://sites.google.com/site/tandycocoloco/dropbox

but in the form it is is only useful to copy from a disk image file to a
floppy. You must format the disk before as os-9 even if it's not going to
be an os-9 disk, and then copy it using:

 rawcopy hitchhike.dsk /d0@

of course you must have the disk image in your hard disk otherwise it won't
work as I cannot read (using I$Read) from a non os-9 floppy, it will stop
at the LSN0.

Just an idea, imagine if we had a special option to the DW server, like
HDB-DOS emulation we would have OS-9 LSN0 Fooling, DW would add and
artificial LSN0 based on the disk geometry. For the backup utility it just
need to skip the fake lsn0 and proceed with the copy writing the real lsn0
at the end.

Or, we can go for a low level access to ignore the lsn0, creating a special
os-9 driver maybe ?

just putting ideas on the table...
