ADFSBuffers - Acorn's recommended settings

On any computer fitted with RISC OS 2 or RISC OS 3.00 we recommend 
that ADFSBuffers is always set at zero.

With RISC OS 3.10 it is possible to increase the value, however there 
is a slight chance that data on a floppy disc may become corrupted if 
ADFSBuffers is not set to zero. This only applies to the A3010, A3020, 
A4000, A5000 and A4. With these machines we recommend that ADFSBuffers 
is set to zero using the following process:

1) Save any work you wish to keep
2) Press F12
3) Type Configure ADFSBuffers 0
4) Press the Return key twice
5) Shutdown and switch off the computer. 
6) Switch it on again after at least five seconds have elapsed.

In situations where no critical data is being handled you may benefit 
from an increase in performance if you set ADFSBuffers to 4 or 8 instead 
of zero.

Please note that switching on your machine with the R or Delete keys 
held down will reset ADFSBuffers to a non-zero value, so the process 
above must be repeated.

We have been investigating the cause of the problem, and hope to 
introduce a fix as soon as possible to allow ADFSBuffers to be set above 
non zero on the machine type listed above.

Installing Desktop C on non-Acorn Filing Systems

We have now prepared an alternative version of the !Install program 
which will work with some third party Filing Systems which the present 
version cannot handle. If you experience problems installing Desktop C 
please write to Customer Services to request a copy of the new !Install 
program. Before doing so, check that all the discs you are using are free 
from defects using the Verify command. You should also check to ensure 
that there are no clashes between the media that you are installing to 
and the floppy discs - check that there are no files which have the same 
name as directory on the floppy disc, and that there is sufficient space 
on the destination disc.

Connecting A3010/A3020 to older Acorn monitors

Some people have asked for information about connecting an A3010/A3020 to 
earlier Acorn monitors such as the AKF17. Acorn do not supply a 
connecting lead (since these computers are primarily intended for use 
with AKF30/AKF40 monitors). However details of the adaptor/cable which is 
required can be obtained upon request from Customer Services, and 
ready-made adaptors are available from a number of sources including 
Interconnections (0483 797418).
