Can't get any display with OS 3.9

[Ancalimon]

3 possibilities:

1) If you have the VGAOnly and VGAOnly.info in your Devs:Monitors directory and it might be causing a problem. copy them back to Sys:Storage/Monitors/  and delete them from Devs:Monitors


2) your monitor does not support the saved screenmode

boot without startup-sequence and delete the

screenmode.prefs in SYS:Prefs/Env-Archive/Sys


cd SYS:Prefs/Env-Archive/Sys
delete screenmode.prefs

3) does pressing spacebar in boot menu (hold two mouse buttons) have any strange effects?

[Ancalimon]

if you can see the early boot menu than you must see the Workbench screen too.  They use the same frequency


Try moving the PAL monitor file to storage as well like you did with the VGAonly file.


What happens when you boot without startup-sequence and use the command loadwb  from there?

also try choosing ntsc from the display option and click use and click boot.

[Ancalimon]

Do you have some kind of internal scan doubler?

or do you use some kind of external display adapter?  You should connect your 1084 directly to your Amiga without anything between them.

What is P96 or CGX?  Anything I can do to remove/modify?

Do you have the Workbench disks and a spare harddrive or a card so that you can do a fresh install of AmigaOS ?

If you are seeing the early boot menu properly in both ntsc and pal modes, there's something wrong with your Workbench install.  Probably some library is a wrong version.

boot without startup-sequence

now type the following:

S:
ed startup-sequence

take clear pictures of your startup-sequence text (a couple of them since it should be a long text, simply scroll down and take other pictures) and show them to us.

I don't know about the CF card;

But you can try mounting pc0  to read and write to 720kb double density pc floppies.

I guess it would work when you boot without startup-sequence? anyone?

try to write the following:

sys:storage/dosdrivers
mount pc0:

if it works, you'll be able to copy files to a pc formatted double density floppy this way:

copy S:Startup-Sequence to PC0:

[Ancalimon]

go and get one from the nearest shop!

or take a couple of clear photos to show us what's in your startup-sequence and user-startup files.

run >nil: nil:

SetPatchMrgCop


I bet it's SetPatchMrgCop.

I don't even know what they are for!

the first one looks like maybe the person you bought the machine from made a script which clears the memory.


simply put a  ;  in front of those lines to comment them out (or simply delete those lines) and save the file.  Won't be causing any more problems.

run >nil: nil:

SetPatchMrgCop


I bet it's one of these two.

I don't even know what they are for!


(the rest are mainly assigns to installed programs&games and some lines added by AmigaOS3.9)
