Some questions after upgrading Blizzard 2040 with 68060 CPU

You need to use the proper phase 5 68060 libraries (aminet)if you already haven't installed them.  Also for the fpu to work properly you need to have blizkick in your wbstartup drawer, plus there other third party maths libraries like hsmathlib which give a bit more speed.  There may be newer 68060 patches but thats how I remember doing things for my  A4000 cyberstorm mark 2.  The rainbow of colors you get on on reset and boot are normal and is phase 5's way of announcing to you that you now have the fastest 68k amiga you can get. 68060 is anywhere between 2 and 4 times as quick as 40 mhz 68040

Thanks a lot for your info, that's very useful.:-)

At the moment, even after already doing the install from a Blizzard install disk there is no blizkick in my wbstartup drawer. I will check out the things you mentioned.
 

Sorry blizkick is also useful as it moves your kickstart rom into fast ram, but what you want is cyberpatcher in wbstartup to get the fpu to work at full speed.  this is in the 68060 archive here: http://aminet.net/biz/p5.

btw how hard was it desolder all of the 68040 pins and then resolder the 68060 pins without damaging the board or cpu?

Either way why not just a stick a fan on it to be sure?

Don't forget to put cyberpatcher in wbstartup, as the 68060 doesn't have a full 68882 fpu instruction set, so when running fpu code cyberpatcher is necessary to trap these.  It makes  a huge difference to rendering speed and gives you a more responsive system when these cpu intensive tasks kick in, so multitasking improves.  Speaking of which I found that Executive (aminet, don't forget the key file) a fantastic utility to make multitasking even better than it is.  Just don't run stuff that bangs the hardware like Scala without configuring executive not to schedule it first.  A 68060 is for power users and you need all of the power utilities out there to make it shine
