A4000T not giving video output from my Cybervision64 Card

@Pierre:

Removing these files and directories will remove both CyberGraphX and Picasso96:
ENVARC:CyberGraphX
ENVARC:cybergraphics
ENVARC:Picasso96
ENVARC:Sys/screenmode.prefs
SYS:Prefs/Presets/monitors
LIBS:cgxsystem.library
LIBS:cgxvideo.library
LIBS:cgxbootpic.library
LIBS:cybergraphics.library
LIBS:cyberintuition.library
LIBS:cyberlayers.library
LIBS:vilintuisup.library
LIBS:Picasso96
SYS:Prefs/CGXMode
SYS:Prefs/CGXMode.info
SYS:Prefs/CyberGraphX
SYS:Prefs/CyberGraphX.info
SYS:Prefs/Picasso96Mode
SYS:Prefs/Picasso96Mode.info
SYS:Prefs/PVS
SYS:Prefs/PVS.info

Not all files/directories will exist in your system, but just keep going through the list from start to end.

Also, in SYS:Devs/Monitors you need to remove a file which is called something like CyberVision64, CV64, CVision64, Picasso96, P96. When you find it, also remove its .info file.

A reboot afterwards is required.

Btw, in which way cant you switch resolutions? Sometimes bad software will make it impossible for workbench to change resolution (it cant close the screen). The only way then is to select a resolution, save and then reboot. You will then have the new resolition at next boot. Try disabling everything in your WBStartup and User-Startup and then see if you can switch resolutions then.

Patrik,

Yes the cybergrahpx Vs. the AGA video output does makes sense.  Riddle me this if all else could the motherboard be at fault here, which is my worst fear!


At the moment Im not at my computer :-(..
the monitor is a Viewsonic 19" not sure which model but I will find out..I also
been useing an Idek 17" you know the one they used to sell just for the Amgia
way back when..
Resolution is 1024x768..nothing too crazy and with out being at my Amiga not sure the frequencies..

I have full confidence that we/I will get this up and running again..but has anyone run into a similar problem and the fault being the Motherboard???


Again thanks for everyone helping out with this!!!Just to let everyone know that I have been an Amiga fan since before they were released and a proud owner since 1988..

i am just about to do this purge. thanks.

currently I can not even view the cgx displaymodes in the screen mode selector.  they are not available.  hope this fixes it.

[Vlabguy1]

If you could please post your results..
Thanks
Rich

so far removing the files..rebooting...reinstalling 4.1 drivers did not work.  I am "pretty" sure the card works and totaly sure the computer is working so it must be something with my OS/install. it pains me that i will try this fresh install and then maybe have the same result!  I must be doing something wrong?

[zipper]

Have you 3.9 BB2? You need better than CGX 4.1

This has v42.7 lib:

Thanks for the reply.  Im actually running OS3.1  The Cybergraphx software intalls fine and Im able to select screen modes from the prefs. but when I
select a CV mode the computer does the switch but with out any output to
my know working monitor.  

I ask again could this be a Motherboard problem???

Thanks again
Rich

take a look in SYS:Devs/monitors/ if the CV632D(?) file, have its icon.

I know that this isn't totally on subject, but for future reference I suggest that you take a look at this photo that I posted: Important C64 3D graphics card mod

Sorry if your board isn't the same, but drivers or no drivers, monitor or no monitor, the two lattice chips on my C64 3D run aufully hot. If your gfx card has one of these chips and its cold after a hour with power applied, then i'd suspect that it could be fried.

@zipper
that would explain a few things... VERY good info, I did have 3.9 with boing bag 2 and rom update!  
I'm am a bit frustrated as I have now reformated my "very nice install" ripped my 060 mkII out of the box!  I reinstalled 3.1 but now can't get the cdrom back online!  I'm sure all my hardware is working I just don't know if I have the time to EVER get it back together...all becasue I wanted to make a simple change.  The cv64 should go into the a3000 so that I can use the built in scandoubler with the monitor switch on board and the cv64/3d would go live in the a4k... SHOULD be easy!  The amiga is not "Plug and play" and is a far cry from it... it actualy has the WORST system for upgrading and installing hardware AND software that I have EVER seen.  Wnat to change somethign on the system ... gee forget all the time you spend setting things up becasue now you have to redo it all again... I hope that morphOS or OS4 have figured this stuff out becasue the classic sucks!
Sorry for the rant but I needed it.
thanks for the help.

PS.
No I do not think your motherboard has anything to do with your issues, it's (bad) software.  If your mother board had issues you would notice that BEFORE you even got the cv64 install.

@Pierre

Thanks for the PS at the end of your post!! I will keep that in mind and now
not lose any sleep over this one.  Im going to try a Retina Z3, then
a PicassoIV..then trying to think of some other boards I have that I could
test.  I prob wont get back to til this Sat.  
But Im still confused as to how I have bad software..which is could be
bad my OS 3.1 or the Cybergrapx??

Thanks again for all your intput.
Rich

[pierre]

rich, I think its your  monitor config.  Your monitor is not syncing..  what did you set it to during the install.  I gives you a list to shoose from ... 80htz....ext. try a lower setting see if that helps.  bad software, i mean botched install....

[Vlabguy1]

Pierre

Thanks for the response.  Even though I have done several installs I will keep
trying.  My worst fear is that the motherboard is toasted, which would not be
good :-(..And I dont even know how that would be possible.  I will post any
and all results for sure.  If anyone has/had  a similar prob. let me know what
happened with that..please!
Thanks again
Rich

Just one more thing..I tested all the ports and I have a voltage loss on the serial port???  Could this be a failing PowerSupply and could this effect my
Screen mode switching??

I know its a long shot, but I figured I would ask

[patrik]

@Pierre:

You don't need to reinstall your system.


@Vlabguy1:

If your motherboard was toasted, you would not come as far as being able to select a CV64 screenmode. And when on the subject - how in the world would you have managed to fry it by reinstalling the os?

Btw, what processor card do you have? If you have the stock Commodore 040-card, make sure you have 68040.library in LIBS:, if you have say a Phase5 040 or 060-card, make sure you have their 68040/68060.library in LIBS: installed correctly - see this thread.

If the libraries are not ok, the most odd things can happen as they help set the cpus caching policies etc. correctly.

Patrik,

Could just the video output part of the mother board be fried??  I didnt mean to imply that reinstalling OS would have fried the motherboard..Sometimes these things just burnout.  It is an old machine, although with very low hours.  
The 060 card that is in the machine is a QuickPak(I believe)board.  Which has
been running just great!!!
The more I learn you all of you Im beginning to think its a software thing.  
Well, speaking of odd things..could a incorrect OS install cause this problem?
Has anyone run into similar probs with the video output to a graphics card?
Im hoping it just a syncing problem and nothing permanent.

Thanks again Patrik!!

Long live AMIGA!

@Vlabguy1:

1. There is no video output part of the motherboard, which the CV64 depends on in any way.

2. As you have a 060-card, you MUST install the 68060.library correctly, or else the OS3.1 will think you have a 040 and try running it with the 68040.library. This is NOT supplied with OS3.1, and there should be a disk bundled with your card containing this.

As 3.1 does not know of 68060.library, there should also be a "dummy" 68040.library with the 68060.library on the disk, which should replace the Commodore 68040.library. Its only task is to load 68060.library when the OS asks for 68040.library.

So in short - there should be a disk bundled with your card, containing two files called "68040.library" and "68060.library". Just copy those two files to LIBS: and reboot.

If the 68060.library is not correctly installed, much will act wierd and it is very very possible that the graphics card will be affected.

3. Does the monitor you have connected to the CV64 remain in powersave mode or similar when selecting a CV64 screenmode with Prefs/Screenmode, or is it "active", albeit with a black picture?
