I figured out that the command C:Wicher LOAD CFGRAM causes the system to reboot with a guru.

If I comment that line out of the s:wicher-startup file it loads workbench but I am left with a strange number for FastRAM. Usually something that looks like 10 12 or once even 18 MB of RAM. The system then eventually fails and reboots, even at 7MHz.

I am using rev.2a which I bought from Inertial Computing. I downloaded the Wicher Installer v2.2 adf file from the Retro 7-bit site. Is there a mismatch with the software perhaps?

I should also add that I am using an NTSC Amiga 500 Rev 6A with Kickstart 2.05 and Workbench 2.1. I also have a 2MB Agnus/2MB ChipRAM board installed.

What exact version of Kickstart do you have? 37.350?
