Title: MOS for powerup reset problem
Post by: Flashlab on September 29, 2007, 04:18:18 PM

When I reset my Amiga when it's running MOS for Powerup it enters a reset loop and the powerled keeps blinking. Only when I power off I can reboot into AOS.

Does someone know could cause this?

IIRC it is not 100% guaranteed you could reset machine safely from PPC only mode. There was an explanation but I can not remember it anymore.

Pushing CTRL+Amiga+Amiga down 10 secs could help, or maybe not.

That actually does help. Maybe it has to do with the MapRom feature?

You're advised to disable maprom before launching MOS, esp if you're using for example BlizKick extresbuf.

I am using Blizkick with extresbuf. But in order for that to work I have disbabled maprom already in the CS-PPC menu.

Is there a way I can make this work?

Start blizkick without any options to remove it from memory. I had some script that would remove blizkick from memory (it reboots if bk was active) and then launch MOS if RMB was held down at boot.

So on the AOS side startup sequence:

Code: [Select]

rmbcheck ; or whatever you use to check for rmb
if warn
  blizkick >nil:
  moslaunch ; this was a script
else
  blizkick with normal options here...
endif
So if you powered the system up and held down RMB it would reboot and start MOS. If you had started the system with BlizKick already, it would reboot twice and start MOS.

But how do one make a script reset proof? Or did you held down right mouse button all the time??

@doctorq
I held the RMB thru the two reboots.

Obviously if you find this unbearable you could hack some temporary script copied in place that'd do then thing. I didn't need anything that fancy personally.

Blizkick without any arguments gives me the error that Kickstart restoring is not supported.

If I cold boot and start MOS right away the reset problem isn't happening so the problem lies with the Maprom.

Gah. I guess I never got the restore work with CS PPC then.

Bummer... Would it work if I rekick with a plain 40.68 image?

EDIT: Just tried and alas no...
