Picasso II Is Making A2000 Lock Up

[dannyp1]

For the first time I was trying to install a Picasso II card in my A2000.  It seems to work ok until I start opening windows.  If I can get the drive icon to open a window I usually can't open the next drawer.  The icon will light up, and the computer freezes.  I can still move the pointer around but can't do anything.  The icon I double clicked on stays lite up.  Any ideas?  I figured I'd ask before I started going through a long process of trying to eliminate things.  I have an A2000 R6.2 motherboard.  G-Force 030 accelerator with 16 megs of ram on it.  Megachip for 2 megs of chip Ram.  ECS chip set.  Lisa flicker fixer in video slot plugged into the Picasso II.  I changed it to a picasso 600X400 screen mode and was stuck there and not able to do anything.  I had to physically remove the Picasso card to be able to change screen modes to an ECS supported mode to be able to do anything with the computer.  Any ideas or something obvious I'm missing?  Thanks,

I should mention I have 3.1 roms and OS 3.9.

Are you using P96 from OS 3.9?

[dannyp1]

No, as of right now I am only using what is loaded from the Picasso II install disks version 2.2  I have not installed P96 yet.  I also have seen that there is an install disk version 2.4 that I could download.  I didn't want to get too far along installing more software until I had a little better handle on what was happening.  It would throw more variables into the mix but maybe I'll have to.

Two suggestions:

Make sure you have set the jumper for the Picasso's memory to either use segmented or unsegmented (recommended).

You may also want to install enforcer as there may be conflicts between the 68020/30 caches and ZII memory accesses to the Picasso board.

If you're using an old Zorro II memory board you may want to make sure the dram chips on it are at least as fast or nearly as those on the Picasso; if there's a wide discrepancy between the speed rating (e.g. 150ns on the ZII memory board and 80ns on the Picasso) you could be asking for trouble.  Generally, I've had no problem with 100ns drams on a ZII board and 70 or 80ns on the Picasso II.  It's worth a shot.

And also make sure all those dram chips on any memory board, including the Picasso are seated properly.  You could even try reseating the ones on the Picasso in case there's a bad contact.

Forget that outdated Picasso software. And you must get rid of it completely, it may cause problems with p96. Not to say that I was quite happy with that software until I got p96 and noticed the huge speed increase and improved stability (excluding SysInfo, which does work on original Picasso screen but not on P96).
