- =============================
-
- 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:
