[comp.os.minix] Winchester task for the Adaptec-2072 RLL controller

SJONES%HAMPVMS.BITNET@mitvma.mit.edu (Steve Jones) (10/31/88)

Greetings All,

        My latest sob story is that the machine I was using in the
computing center here was momentarily taken out of service to
install a new 3.5 inch disk drive. The bad news is that for some reason
they decided to scrub the hard disk and start over from scratch. This
tends to result in elimination of the Minix partitions on said device,
and can slow down development efforts on a given machine.

        So while I recover from the shock, I thought I might see if anyone
has modified the XT winchester task to communicate properly with the
Adaptec 2072 8 bit RLL hard disk controller. I would also be interested to
hear if someone has run a Seagate ST-277R successfuly with the above
controller. I am not quite certain, but I believe that this drive can
be accomodated with 16 bit addresses (retailers claim a capacity of from
60 to 65.5 megabytes for this drive). Reassurances would be welcome.

        If you are kind enough to send source, please send a complete
source rather than diffs or whatever variety, and please, no encoding
other than p'rhaps uuencode or Listserv-PUNCH. I have attempted to use the
posted patches I could find for the Adaptec-2072 with an ST-238R, but
so far to no avail (I didn't try hard-coding param0 and param1 - I
was going to when I discovered the tragedy outlined above).

        Thanks in advance to everyone who replies. Please EMail or SEND/FILE,
and I will post a summary.

--Steve.
