A1200 Freezing problems...

[mfilos]

Hi guys,

I have an A1200 revision 1B mobo with an Apollo 1260@66mhz accelerator with 64MB RAM.
After I had my 1240 upgraded by PG succesfully and running great I discovered that from time to time my Amiga freezes and I have to reset. This happens EVERYTIME I run WhichAmiga and sometimes on MUI programs, MagicMenu etc.
Despite SysInfo and SysSpeed didn't give me any problems, I tried MemTest and saw that I got some errors in my Memory modules. I decided then to change my SIMMS to new ones. I got a set of 4x32MB SIMMS that I used and everything worked just fine with the same freezes though.
I then realised that it could have been the PSU that I was using from an A500. I guessed that maybe FastATA+ScanMagic+Subway could cause this instability due to lack of power.
Yesterday I received at last my DBox, Mediator, Voodoo3, SB128, NIC so I guessed it was the only way to find out!
Everything worked just fine and run without problems with Picasso96, USB works just fine, accelerator just fine but guess what?... Same freezes in WhichAmiga or sometimes on WB screen on Boot.

I haven't made a post all this time since I didn't knew about whether is was a Memory problem or PSU...
Now though... I'm kinda out of ideas except one!
The only thing I can imagine would be a mobo revision thing as timing issues. The fact that it's neither a 2B or 1D.4 (in order for me to perform the timing fixing hacks) doesn't leave me with options of what to do.
Since 1B is a really old mobo revision, does it require BOTH timing fixing hacks? Does it requires something else, or it's a general issue?
Does anyone having an Apollo 1260 with a revision 1B mobo had the same issues or is it another problem?

I find it extremely irritating not being able to use my Amiga after investing so much money
I don't have a problem searching for another mobo (1D.4) but I wanna know for sure that I won't have a problem or in the best case... If I can make my current mobo to work flawlesly with my current setup

Cheers and thanks in advance

Thanks for the reply...

PG has very nicely attached Oscillator female pins on the Apollo Board for me to change easily wherever I wanted the Oscillator to the native 50Mhz one in case I had problems with the 66Mhz Oscillator.
I already tried with the native 50Mhz without any other difference than the speed decrease in SysSpeed and SysInfo.

As for Libs I installed the ones that PG supplied in the disk. I don't remember correctly but I think I also tried the LIBS that AmigaRecource.cx had but no difference again
I think the LIBS are ok. Can anyone PM me a link with his working LIBS to be 100% sure that it's not the LIBS as a first start?

Still it's odd that SysSpeed and SysInfo run ok and WhichAmiga freezes the system while displaying "Evaluating System"

Atm I'm running in an DBox tower so my PSU is not an issue since it's 350W. Apart from that my Libs are the ones that PG supplied to me via a floppy once he returned my board that upgraded from 040 to 060.

I made some progress also:
I tried booting in WB3.1 (without the 040 & 060 libs) via Floppy and WhichAmiga runs now displaying no FPU and MMU not in use. Dunno if that is supposed to be ok since the libs are not present. Fact is that I don't get a freeze :S

I tried putting 040 & 060 out of libs in DH0 in order for the System 3.9 to boot without them to see what it will do.
System booted just fine... So I putted them back :S

You thing that this is the Libs issue for sure?

If so, where can I get the original ones for Apollo 1260? AmigaRecource DMS file?

Any other guesses?

Thanks for the support...

My Setpatch is 44.38 and my system has nothing more than BB1+BB2, MUI, drivers for FastATA/Subway/Mediator/Picasso96 and some progs like DOpus,ShapeShifter.
I tried Thor's Libs with no success. Gave me an error on line 2206 iirc - and that setpatch can't be patched. Anyway I manually copied the 060 lib of that pack but no difference.
My libs are the correct Apollo 1260 libs with a dummy (small file) 040 lib and another (unused i think) 68o4o.library (with o instead of 0 - large one).

Just a little notice before I try it since I haven't got it 100%. You advise me to give a little juice to the floppy connector. You mean the default power connector that supplies the floppy in desktop case? So, I just supply power from a PSU floppy connector --> mobo floppy power connector??? Will it be ok?
