which connector for SCSI?

hi,

I borrowed jason's pc532 so that I could work on fixing the cf_unit abuse
in several machine-specific drivers, and now I want to hook up a disk.

I see two sets of pins that look like the right thing physically:
CONN1 (away from everything else, near the edge of the board) and
CONN16 (next to the ISA-looking connectors that reportedly are really SCSI).
the CONN1 one is also labelled "Disk & Tape".

so just to be sure about what I'm doing here, I can plug a normal
internal-SCSI 50-pin cable into one of sets of pins above, right?
does it matter which one?

The one labeled "disk & tape" goes to the adaptek(?)
chip, which never had a working driver.  You want
the connector near the "ISA" slots (which carry
SCSI signals), which goes to an NCR chip.

There is a Mach driver for this chip, I believe.  I have the PC532 Mach 
sources laying around.  Maybe Chuq feels like writing a SCSI driver :-)

For a userland, it's probably easiest to start with the 1.5.3 release.
-current source can build most programs with a couple of provisos:

  - Pthreads don't build.
  - A handful of programs trip over gcc errors.
  - Lint isn't happy in places.  Sprinkle -k or MKLINT=no
  - Only static linking works.

I think the only programs you really need to use a -current kernel are
fsck_ffs and sysctl.  Maybe vmstat too if you want to use that.

Let me know if you have any hassles.

ok, thanks.  now I just need to figure out which way is up on the cable.  :-)

that does sound interesting.  send me the mach stuff and I'll add it to
my ever-growing list of stuff I'd like to do.

hmm, actually would you mind sending me a disk image?
that'll save me a bunch of messing around.
