Yes the slowness is due to ADFSBuffers not being configured. However if your machine has a hard drive (and I have yet to hear of an A5000 without one) *DO NOT* configure ADFSBuffers on! There is a bug in the RO3.00 implementation of ADFSBuffers that causes hard drive access' to deliver random Address Exceptions, errors and occasionally corrupt freespace maps. Because the errors are random you will have a hard time tracking it down if you aren't aware of this problem. What this means is that you will have to live with slow floppy access' till you upgrade to RO3.1 which has that problem cured. (Mind you it has a nice new one just for fun. Thankfully it is only a real problem when low 8- buffers are configured.) Philip
