precisely, move it from devs:monitors to storage:monitors  8-)

And select a new screenmode But why would you use AGA for desktop use ?? Bvision problems?

[pan1k]

I tried that. My bvision died. and all i get is a blank screen. If i boot with no startup sequence i get a dos shell. help?

Its just an idea.....

....but in this thread Costabunny had an A4000 stuck in the wrong screenmode, so it could be of help to you. Basically she replaced the 'screenmode.prefs' file in Workbench:Prefs/Env-Archive/sys  with the one from a Workbench floppy disk. I also found that deleteing the 'screenmode.prefs' file forced an A1200 Desktop back to HiRes screenmode. Hopefully you have a scandoubler and can boot into a Workbench floppy to gain access to the Workbench partition of your hard drive.

Yeah, when I was having problems with my Cybervision board I just removed the Cybervision driver from DEVS:Monitors/ and then copied over the screenmode.prefs with one from a normal stock WB floppy disk.

It reverts to normal Hi-Res mode then.  But then there is a major PROBLEM.  The new Workbench 3.9 screenmode requester is TOO LARGE for the Hi-RES mode.  The buttons for ACCEPT and CANCEL extend below the NTSC Hi-Res screen.  You can see all your screenmodes listed, and can test them, but you cannot select them the with SAVE, USE and CANCEL buttons because they are cut off below the bottom edge of the screen!  You you cannot then get out of Hi-Res mode into something more useable like 640x400 Interlace, etc.

In a way, this is sort of a bug/design flaw in OS3.9 (unless anyone knows a solution for this).

Hmmm......

Call me mad  :lol: but I've just checked this out on one my my main systems, an A4000 with Picasso-II, scandoubler and running OS3.9.

I put copies of the 'PicassoII' icon from Devs/Monitors, 'ChangeScreen' from WBStartup and the 'screenmode.prefs' file from Workbench:Prefs/Env-Archive/Sys onto a blank floppy disk, and then deleted them all :-o

The A4000 then booted into a rather colourless HiRes Workbench screen and I was able to go into Prefs/ScreenMode and see Save Use and Cancel without problem.

As it was to hand from yesterday, I then also booted into a Workbench 2.05 floppy. There was no problem to swap disks and put the files 'PicassoII' and 'ChangeScreen' back in from here. Oddly enough, after a reboot the A4000 was in 640X480 16Bit without a 'screenmode.prefs' file being present, so there must be a reference to it in another file. But I clicked Save anyway and a new 'screenmode.prefs' file miraculously appeared in Workbench:Prefs/Env-Archive/sys :-)


@ ral-clan

I have indeed come across your problem of not being able to see Save Use and Cancel, but I can't remember under what circumstances.

I wonder if you were able to see the buttons because you have a PAL Amiga (I assume that's what the German developers of OS3.9 also used).  On my NTSC A3000 these buttons were cut off in Hi-Res 640x200 mode.  You PAL users get an extra 20 or so lines of resolution at the bottom of the screen in Hi-res mode, don't you?

Also, as I recall I was using Workbench in "backdrop" mode.  I wonder if I would be able to scroll down to the buttons if it was in "window" mode.

Lastly, I think this problem only happens with the new screenprefs program in OS3.9 and not with the older one in OS3.1.

56 lines that is.

You know, P(lay) A(dditional) L(uxus)  :lol:

I just had a try but couldn't get the screen selection in a scrollable window.

But NTSC could be your problem mate, as I've just switched on an Amiga while keeping both mouse buttons held down. When pressing the SPACE bar at the 'Amiga Early Startup Menu' to switch from PAL to NTSC, the 'Boot' and 'Boot With No Startup-Sequence' buttons move down at least 1" (that's about 25.4mm to us Brits)  :-)

Pressing 's', 'u', or 'c' should work. I don't have a 3.9 machine in front of me right now, but I believe the gadgets have keyboard shortcuts assigned.

If that doesn't work, save the changes manually by getting Save As... from the menu and saving as ENVARC:sys/screenmode.prefs. Then reboot.

[Ral-Clan]

These are all good tips.  As I recall I had tried to use keyboard shortcuts and had no luck.  But I wasn't aware there was a "Save As" menu option, & I had totally forgotten that I could boot up in PAL by pressing SPACE at the early startup menu.
