Science Series II - Materials
=============================
Use of CDROMBuffers:
If you are using CDFS version 2.13 or less, you should configure the
CDROM buffers on your machine to a minimum of 64k (on a 2Meg machine),
or 128k if you have more memory.
-----------------------------
Video playback on 2Meg machines:
As the playback of video requires most of the resources on a 2Meg machine,
users will probably experience difficulties if there are other applications
also running on the machine when the video is played.
-----------------------------
Audio playback with 16-bit soundcards
Some versions of the 16-bit soundcard drivers cause the application to
crash when any attempt is made to play audio. Each time that the
application is started, you will be given the option of selecting 8-bit
or 16-bit sound. If the application has previously crashed when using
the 16-bit drivers, you should select the '8-bit' option.
It is hoped that future releases of the soundcard drivers will cure this
problem.
-----------------------------
Use of the data cache:
This CD-ROM application has a built in 'cache' feature which stores
previous data items in memory after they have been accessed, allowing
quick access to recently viewed pictures & text as the data may not
have to be reloaded from the CD-ROM.
The size of the cache can be controlled from the application icon menu on
the iconbar (Menu=>Cache=>Size=>). There are three sizes: 'small', 'medium'
and 'large' - you can select any one regardless of the memory size of your
machine, although on a 2M machine, the 'medium' and 'large' models give
little advantage over the 'small' model.
If you wish to reclaim the memory used for the cache, you can use the same
menu to free any unused data (Menu=>Cache=>Free). This is useful if you
want to run other applications.

Users of Cumana SCSI Cards CA008 or CA006 with
CDFS Driver 1.17 or earlier may experience some
difficulty running Acorn Replay movies from
CD-ROM. This is due to a compatibility problem
with the latest versions of Replay.
If you experience any problems, a CDFS Driver
upgrade (v1.18 @ August 94) is available from Cumana:
