- This month's column concentrates on the Acorn PC Card, with various hints 'n'
- tips plus details of a software upgrade.
-
- Software Upgrade
-
- Some changes and improvements have been made since this product was introduced
- and are now being checked prior to general distribution. This revised software
- will be available from 1 September 1993. You can obtain it free of charge by
- returning the original Acorn PC Card Software Disc, and Windows Driver where
- supplied, along with your name and address, in an envelope clearly marked
- 'PC Card Upgrade', to

- Running DOS applications
-
- There is a problem with the current version of the software which, under
- certain circumstances, may result in loss of data. However, this problem is
- unlikely to be encountered in normal use and can be avoided.
-
- Using the current version of the software, when running Windows in enhanced
- (386enh) mode, you should not attempt to run DOS applications from within
- Windows itself. This operation is not supported and will cause Windows to
- crash, possibly resulting in loss of data from your hard disc.
-
- It is recommended that you shut down Windows and return to the DOS prompt
- before starting up DOS applications. If you do need to run DOS programs from
- within Windows, do so by starting up Windows in standard mode by using the
- command WIN/s.
-
- Certain benchmarks, such as those provided by Windows User magazine, attempt
- to run DOS applications from within Windows. Ensure that these are only run
- from within Windows when in standard mode.
-
- Games Software
-
- Please note that because games are not always written following good
- programming practice, there is always a possibility that a particular game may
- not run on your PC Card. This is less likely to be the case with commercial
- games than those obtained from free sources.
-
- Using DOS hard disc partitions greater than 32MB
-
- DOSFS, which is an integral part of RISC OS 3, does not support DOS hard disc
- partitions which are larger than 32MB in size. If you create a DOS partition
- which exceeds this size, it will not be possible to access it from the RISC OS
- desktop environment.
-
- DOS partitions greater than 32MB can only be accessed from within the PC Card
- environment. Therefore if you wish to transfer files between a DOS partition
- greater than 32MB and a RISC OS-based filing system, this should be done via
- floppy disc(s) or another DOS partition which is 32MB or less in size. If you
- are unsure of how to copy files, please refer to the chapter 'Files and
- directories' in the Welcome Guide supplied with your computer.
-
- Windows 3 and MemoryMAX
-
- As supplied, by default, DR DOS provides access to additional memory via the
- use of MemoryMAX (MEMMAX) software. During the boot sequence you will be
- prompted to load this software by the command:
-
- Load MemoryMAX software (y/n)
-
- Replying "n" to this prompt will allow Windows to be started in enhanced mode,
- by entering the command
-
- WIN
-
- If you wish to run Windows with the MemoryMAX software enabled, you should
- ensure that Windows is started in standard mode, by entering the command:
-
- WIN /s
-
