The L3FS presumably uses standard OS calls through the ADFS to access 
sectors on the FS partition. So as the ADFS is patched to access IDE rather 
than SASI, it is transparant to the FS what is at the other end. The issue 
was creating the partition in the first place, the formatting program just 
hung when doing the free space test and seeing 512MB capacity, although in 
the loop that tests for available space, it did seem to be limited to 
&1FFFFF (512MB). Limiting it to 256MB ended up with the formatter accepting 
the size, but running out of memory for the FS map, even running on the 
CoPro.

According to Joel, the maximum partition space the L3FS can see in one drive 
is 64MB, so after limiting the formatter to that capacity it formatted 
sucessfully, and the L3FS booted fine and was happily serving away.

Mark.
