Unknown GS error - Help?

[gachenb@eis.calstate.edu (Greg R. Achenbach)]

Last night, I was trying to install ProSel onto the RAMDisk in my ROM 1 
GS with 4 meg PaceMark SIMM memory card.  Things were going along fine 
until I got this error:

>PY/COPY.GSTOREMML
error occurred - press a key

Any ideas?  Thanks in advance.
