Title: Amiga 4000 + 3640 Kickrom issues
Post by: direktorn on May 13, 2013, 10:51:14 AM

Hi,
I'm trying to kick 3.1 on my Amiga 4000 but most of the times end up in issues. If i start the computer cold it mostly works, it kicks 3.1 and reboots and WB loads. But after some time things start to crash and when i try to reboot it just crashes on the way (Wb never loads) and it's stuck in a inifity loop.
 
I'm not sure if there is a issue with the 3640 and MMU or other hardware stability issues. The amiga is a stock 4000 with an AriadneII, Picasso IV and GPV SCSI card.
 
I have tried cybermap and blizkick with the same results.
 
Any ideas about what could be wrong?

Define crash. Can you get it to boot to early startup? To no startup-sequence?
Freeze with screen colours? Guru? Keyboard caps-lock toggling for more than 10 times when crashing? Floppy drive clicking? Does it reboot itself?
What kickstart version are you kicking to and from?

The instability hapends on a software level - I can get into early startup. I get a GURU error before WB loads.
 
Kicking from 3.0 till 3.1
 
It always works the first time from a cold boot. So something is happening after the kick. The kickfile comes from my other Amiga 4000 with 3.1 roms.

Same each time?
Can you give some examples?

Check which version of 68040.library is in LIBS: or if it's there at all.
