Title: A1200 Yellow Screen
Post by: Retro_71 on November 28, 2007, 05:32:30 AM
Hi all,
Sometimes when i boot up i have a yellow screen, anyone know what the problem could be?
Also i have notice that my HDD is starting to act up and lose partiations. i have tried 3 drives 2.5" IDE although they were old the 20GB is not that old but i still get the same probs. i am getting a new ide cable (could that be the prob).

Thank you in advance.  :-D

Yellow screen normally means a CPU problem, so try re-seating your accelerator.

What your Amiga is telling you (http://www.amigahistory.co.uk/selftest.html)

As Moto says, it sounds like a hardware issue.  Check all socketed IC's under the hood and reseat them if neccecary.

I recently read that an A600 owner had the same issue with a buggy memory expansion.

Reseating them seems to have work 15 shut downs and no yellow screens. BUT my HDD is acting up when i put wb 3.1 and partition and then format the drive all seems ok until i reset or shut down then when it loads up it says DH0: not a DOS disk  :-(  Any ideas?
I have tried it with 3 HDD a 580, 720 and the 20gb (i have a 40GB somewhere should i even bother?) but i get the same problem.....  :boohoo:

Your problem could be related to the Max Transfer Size variable used by the file system:

and a visual tutorial:

You can also find tons of references to this by using the crappy search function on these forums.

Good luck!

Problem Solved....  :-D
Solution:
Although i have a 20GB Drive Wb3.1 saw it as 8GB fine. But if you use the default partition 4031/4031 only one partition is active (last parition formated) even with the different maxtransfer it didn't change that one partition ended up as NDOS. So i finally remember what i did years ago and took off 80mb off each partition and it worked..
My own fault for being out of the Amiga community for so long (won't let that happen again!)

Thanks for all your help with this.

Next step make sure overdrive works and get OS3.9 on there ASAP  :-D
