CD-ROM Drivers for Aleph One !PC system
==========================================

To use these you will need a copy of MSCDEX.EXE from Microsoft.

There is one file provided to enable CD-ROM drives to work:

A1CD/SYS is an MS-DOS device driver for MSCDEX.EXE; you should transfer it
onto your DOS boot disk and put a line in CONFIG.SYS similar to this:

  DEVICE=A1CD.SYS /D:MSCD000

You should also copy MSCDEX.EXE to a suitable place and include the line

  MSCDEX /D:MSCD000

in your AUTOEXEC.BAT file.
                                                                 


Error Messages from A1CD.SYS
============================

ERROR! Invalid line in CONFIG.SYS

  Means some of the text following "DEVICE=A1CD.SYS" is incorrect. Currently
  you may only have the phrase "/D:name" after this. 'name' is the name by
  which MSCDEX will know the device driver - it should be no more than 8
  characters long. If you do not have "/D:name" the name will default to
  'MSCD000'.

ERROR! Cannot find Aleph One BIOS services

  You are trying to run A1CD.SYS on a system which is not an Aleph One 386PC
  card, e.g. a normal DOS system or the Acorn PC emulator. This error may 
  also occur with very old (pre 0.79) version of the !PC application.
                                                 
ERROR! No CD-ROM drives working

  The !PC application has been unable to find any working CD-ROM drives. This
  may be because the drive is switched off, or the Acorn CD filing system
  and driver (CDFS) is not loaded, or you have not configured .
