I have installed SunoS 4.1.4 on a an IPX and then tried to start Open
Windows 3 from the command line.
I get a garbled screen that looks like this:
http://i.imgur.com/jWcbqYO.jpg?1
It looks like there is a mismatch between what resolution Open WIndows is
using and how the frame buffer is configured. My screen reports that the
framebuffer is outputting 1280x1024 at 76Hz.
How can this be adjusted? I have read this manual:
http://bitsavers.informatik.uni-stuttgart.de/pdf/sun/openWindows/Open_Windo…
and various FAQs trying to modify EEPROM settings etc but it won't work.
I understand that the 13W3 cable includes a number of sense lines so that
the framebuffer can adjust to the monitor used. I haven't checked how 13W3
to VGA cable is configured but I assume it tells the FB to use
1280x1024 at 76Hz since it is what the screen reports.
On the other hand, when SunOS boots it finds the cgsix0 and reports that
the resolution is 1000x1022!?
Any idea on how to set different resolutions in Open Windows? What I am not
understanding here? The word resolution is not even mentioned in the
Installation manual for Open Windows above...

I think you may need to
force the display if you can to the 1000x1022
resolution. That doesn't sound too far off what I recall the
resolutions were.
are you connecting into the thing thru serial so you can poke around? I
don't recall for sure if the default loaded system allows serial login,
but you might be able to get on thru the serial port and adjust things
as well. I didn't read the guide above, this is from fighting with the
systems long ago.
I used a box that was made by Raritan or such to convert the video and
keyboard to allow connection to VGA KVM and those boxes had some active
circuitry in them to do things with the selects. They weren't doing
anything as far as sync adjustment, but may have pulled a different set
of settings to both the Sun system and to the KVM and on to the
display. I did not have much trouble with that, so don't recall having
to play with the frame buffer settings.
thanks

Sorry. I failed to mention that it works fine at the SunOS prompt. I have a
standard text terminal so I don't need to have a serial until I bring up
Open Windows. But how can I get it to use 1000x1022 anyhow. It seems that
when it start up it is at 1280x1024 at 76Hz probably because of the sense
lines.
If I am able to change the sense lines I could probably set it to 1152x900
according to this table: http://pinouts.ru/Video/SunVideo_pinout.shtml
But it would probably hard to do it without some kind of adapter or surgery
to the cable.
The 1000x1022 resolution is not on the list so I doubt that I can force it
into that easily, or? And 1000x1022 is a really strange setting anyway.
Where does that come from?

Do you happen to remember what resolution you were using?

It does.

If it's a "modern" flatscreen, don't necessarily trust that. I've
seen
flatscreens claim some very, um, "creative" things about the input
signal if it doesn't use quite the sync timings the screen wants (which
are, of course, invariably undocumented).
For example, my usual desktop machine is a SPARCstation-20. Years ago,
I figured out how to get them to generate resultions the ROMs don't
account for. Recently, I tried to drive a recent flatscreen with a
SS20, and, while fidding with the various timings, I had the flatscreen
report wildly ludicrous resolutions when all I was changing was the
sync timing.

That's...odd. I can't help wondering where it got that. Out of all
the framebuffers I've poked at, I've never seen that resolution. The
usual resolutions close to that are 1152x900 and 1280x1024, and those
are landscape, not portrait.
If you can test-boot NetBSD - from a CD or from the network, for
example - I'd be interested to hear what it thinks the resolution is.
Also, if you can capture printenv output from the ok prompt, I'd be
curious about that too.
