I recently upgraded my Indigo Elan to 4.0.5f and found a strange thing
happening with gr_osview.  I use the following .grosview:

  cpu tracksum(5)
  rmemc
  pswap
  opt noborder arbsize origin(1073,650) winsize(200,150)

What appears to happen is gr_osview is interrupting the graphics pipe.
Approx every 2 sec (the gr_osview's sample time) any graphic activity
freezes.  Pyro is erratic, any object in a free spin will momentarily
pause, ...

If I kill gr_osview and restart it with 'gr_osview -a', I do not get
the graphic interrupt.  If I restart it with my .grosview, the
interrupt returns.

The only thing that I can guess is that changed size of 
gr_osview is causing it to interrupt the graphics pipe.

Anybody seen this and/or any suggestions ? 
(Other than don't change the size of gr_osview)

This is true. The development option is quite reasonable value. You get

going to economize on anything, go for third party RAM and peripherals.

We bought our Tahiti II directly from MaxOptix.  After much
difficulty we finally found out that S1 #7, labelled 
"disable unit attention" must be ON when the drive is
connected to a Macintosh.  Since the error messages you
quote mention "unit attention" I suspect this is also
true for SGI drives.  The Unit Attention state occurs
when a SCSI bus reset takes place; it is a way for the
drive to tell the controller "check my status BEFORE you
do anything else."  Many controllers ignore this
request, and try to acces the drive anyway.

Perhaps somebody from SGI can tell us whether I am correct
about all this as it applies to SGI hardware; I've never
tried the optical drive on our SGI so I only know what
happens with Macs.

	No we do not offer a "dumb" graphics terminal.  If you can get by
without GL graphics you could add an X terminal.  It would be useful for
everything you do except GL rendering.

On a DS3100 with Ultrix 4.2a.

While the functionality is clearly correct (ie it does return the
proper directory/name) , "tempnam" does consistantly return a 
ENOENT errno, as does "tmpnam".

I think the easiest way out would be to put a symbolic link in /usr/tmp
on the server, to point /usr/tmp/shmtrans0 to /tmp/shmtrans0.  On each
client, if /tmp is local, the link will point to the local version.

This is a problem with the printer's "emulation sensing" mode.  You

The standard Unix utility "compress" comes with most Irix versions
(type "man compress" for instructions).  Is that what you need?

Source code for that is probably impossible to get unless you have
an *expensive* source license; do you really need source?

I suspect that you are logged in as root, since "." is not already in 
your path. The path for non-privileged users contains "." by default. 
Look in a sytems administration text (e.g. Nemeth et.al.,  Farrow & 
Thompson) to see why it is not a good idea to have "." in the path for

I'm sure you meant that D/A converters have 18-bit resolutions
as mentioned in "relnotes eoe 13" in 4.0.5F.

Now, I figured DSP56001 for audio interface control handles 24-bit
audio data with digital I/F, and 16/18 bits of them with analog I/F.
Is the rest of the lower bits simply masked to zero when transferring
a 16-bit A/D data to GIO-Bus or digital I/F, and when supplying 24-bit
AIFF data to 18-bit D/A converter?
Is there any chance to upgrade the A/D and D/A converter to a higher
resolution considering that there are such as high as 20-bit reso.?

What about the new machine with R4400?  Is the audio interface going
to be the same with Indigo using 56001?

Thanx in advance.

  I am happy to report that this does indeed eliminate the ugly artifacts.  I also

I have added an alternate df1 data file to the ftp site. It contains the Earth elevation 
data and a simple color scheme based on the elevation (blue+green+white). I have also
documented the 'u' key, which can be used to change orbital characteristics
in conjunction with 's' (inside star system, press'u', press 's', use mouse to select
planet, use mouse to select stat, enter new number with keyboard<ENTER>). It's handy
for moving planets around or altering the axial tilt. A good one is to set the orbital
period to 100000000 and then make the planet rotate fast on its axis.

I don't know how it tries to read the capacity, but as I recall, the
readcapacity command fails on CD-ROM drives when no media is present.

Furthermore, the SGI drive defaults to 512 byte logical sectors after
power on or SCSI bus reset, and the NeXT probably won't try to set
the logical size for most apps, so you may have to write a short program
on the NeXT to set the logical block size to 2048.

Audio disks use a different command set, and the logical block size
is irrelevant in that mode.
