Reinstall OS4?

Just a quickie - do I need to reinstall OS4 if I've changed my Blizzard PPC card from an 040 model to a 060 model? (Different card - not an upgrade)

Cheers!

I don't think you need to reinstall. The 68k is deactivated by OS4 anyway.

@thomas

The word "Reinstall" Is an invention made by Micro$oft.
Its the same with "Reboot" "DeFrag".

Not an invention made by hyperion :)

Better ?

1)

The 680x0 JIT emulator (Petunia) thats built in to OS4 emulates the 680x0 faster then a real 680x0 CPU, programs are also highly accelerated by OS4 native system files, when they are used.

2)

Emulating the 680x0 CPU eradicates the need for context switches between to two CPU's, the result is no cpu cache flushes needed, the need for cpu cache flushes needed was always a problem whit WarpUP/PowerUP in the past, and has always resulted in slow downs, when ever AmigaOS3 communicated whit WarpUP OS.

3)

It's a shame that Petunia can not be used in UAE, because it does not support offset addresses as required by UAE.

The 68k CPU is killed at the startup, os4 is PPC only so you do not need to install os4 a second time

@badgerme

Did you get all those repetitions?

Just to repeat the answer once more: "No".

@tonyw

lol - yeah - I think I get the idea... so that is a 'No' isn't it - just want to be sure! :)

@badgerme

Pretty much.

@LiveForIt

Offset addresses? What is that? (I don't know how UAE is working internally, so forgive my ignorance.)
