A1200 Freezing problems...

I had similar issues, the machine would hang (sudden black screen) during boot, or shortly after while running something CPU intensive, regardless of clock rate. Adding juice to the floppy connector solved the problem for me. (Only happens with one of my A1200 motherboards :shrug:) As has been pointed out though, I would certainly check software first.

Cool. In some cases though, the expansion port can't supply enough juice for the card to run reliably (there is a voltage drop between the PSU port and the expansion port). Plugging a floppy connector from your PSU to the floppy connector on your A1200 motherboard will help (fixed random "hangs" in my case). Actually, this is probably a good idea to do anyway.

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?

The libs from PG are the original libs, and should work fine. Make sure you're using the correct 040 lib, you want the (very small filesize) "dummy" 040 lib as opposed to the normal one (for 040 cards).

-edit- If you like, you can try Thor's libs, they work fine on my 1260 card.

OMG, WhichAmiga crashes my rig too! Piru, WTF?? :lol:

Actually, it seems to have something to do with my RemApollo/modified KS setup. When I use the Mu tools for remap/etc, WhichAmiga works fine. It also works fine with a bare 3.1 install and Apollo CPU libs, and again with *no* CPU lib. (I'll see if I can narrow down what does cause the crash.)

Another thing I just remembered, later versions of SetPatch (at least 44.38 here) load the 68060 library directly, so you don't need any 68040 lib in that case.

OK, weird. At first I thought there was a clash between exec441 and WhichAmiga, as WhichAmiga would crash using a ROM modified with exec441 (and compiled with Remus), yet no crash with a clean ROM "grab".

Turns out, WhichAmiga crashes with my funky combination of using RemApollo with the MMULibs/MuFastZero (discouraged in RemApollo docs) -- but ONLY if the ROM has been compiled with Remus! With a remapped clean grab, there is no crash. Split the ROM and compile (without changing a thing, aside from perhaps the order of the ROM contents), and WhichAmiga crashes.

Anyway, sorry to get a little off topic. Bottom line in regard to WhichAmiga crashing and the Apollo 1260: It should not, using the Apollo lib, Thor's lib, or *no* CPU library at all, on clean 3.1 or 3.9 installs. (Remember that 3.1 will need the dummy library, as the computer will crash during boot with the wrong 68040 library.) If it does, there may be a hardware fault/timing issue somewhere. (In the case of having a bunch of expansions, you definitely should add juice to the floppy connector.)

So, I just supply power from a PSU floppy connector --> mobo floppy power connector??? Will it be ok?

Yes, it will be fine, no worries. :-)
