If i am reading right i see you are trying to map 10MB into zorro2 space,and only 8MB is allowed.seems you have a conflict there,try removing 2MB off the GVP or supra(maybe just yank the supra temporarily to see if it runs stable?)
if all fails put the mask back to what it was before and see if that helps.
You shouldn't be using a mountlist with a autobooting hd controller,you would change the mask with hdtoolbox or whatever your using(gvp tools) in each partition in the RDB.
you mention your settings drop the 2meg of ram off the MMR when you drop the "dram" command.. Are you sure the 2MB on the MMR is good?-bad ram can cause you headaches. IS it in the right sockets? is it actually 2MB? double check this and verify it.
as for the commands in the user startup,its probabaly fine there since it just gets started later. but a Run >NIL: in front of the line may help the popup requester issue.
The MMR is a cantankerous piece of equipment when combined with other old boards sometimes. Your best bet would be adding a full 8MB to the MMR,since its 32bit ram-it will be much faster. ditch the 16bit ram boards. i have had trouble in the past with 32bit ram and 16bit ram living together with some cards but i dont think this is your trouble(yet)..
