Hi anarcholab
Thanks for getting back to me.
The problem appears to be just with TOS 2.06. It might not be worth your time fixing it. I think I'll buy a TOS switcher.

I tested a few combinations:
** STEEM
* .ST image
STF 1MB RAM TOS 1.02 **OK**
STE 1MB RAM TOS 1.06 **OK (autoboots)**
STE 1MB RAM TOS 1.62 **OK (autoboots)**
STE 4MB RAM TOS 1.62 **OK (autoboots)**
STE 1MB RAM TOS 2.06 **4 bombs reading disk**
STE 4MB RAM TOS 2.06 **4 bombs reading disk**
* created new .ST image and copied LASER15 folder over
STE 4MB RAM TOS 2.06 **hangs on 'LADEN'**
** REAL HARDWARE STE 4MB RAM TOS 2.06
.ST image: **4 bombs reading disk**
new disk: **hangs on 'LADEN'**
