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

This driver will work with all CD-ROM drives (SCSI, IDE or Parallel
interfaces). You must already have the drive installed so that it can be
accessed on the RISC OS desktop.

Supplied are:
------------
HPC_CD/SYS (v2.0 1995.11.29), device driver, from Aleph1
MSCDEX.EXE (     1993.09.30), CD extensions to DOS, from Microsoft
README/TXT - this file.


The device driver (HPC_CD.SYS) is necessary for the device to be recognised
by the PC Card. The CD ROM extensions (MSCDEX.EXE) are necessary for DOS to
use a CDROM drive. A modern version of DOS will include a copy of MSCDEX. Use
that in preference to the one on this disc, which is only supplied for those
who do not already have a version of the file.

Note that HPC_CD.SYS supercedes the older driver A1CD.SYS which will not work
with !PC v1.99 or later. Remove this older driver, which may be in your
C:\DOS directory, as well as C:\DRIVERS\CDROM.


Installation
------------
These files should be installed by !PCInstall, as described in 'Installation'
in the main Readme. It is possible to install them manually if necessary, as
detailed below.

Manual Install
--------------
You need the HPC_CD.SYS file in the directory C:\DRIVERS\CDROM. It should be
put there by !PCInstall. If not you need to read the Unpackers ReadMe for
details on manual unpacking.

[See Issue 6 Manual section 6.11 CD-ROM, noting that the name of the Driver
itself has changed from A1CD.SYS to HPC_CD.SYS]

NB: Before editing DOS text and System files you must read the important note
in Section 5.5 of the Manual (Editing DOS text & system files).

HPC_CD/SYS is an MS-DOS device driver for MSCDEX.EXE; you should copy it from
C:\DRIVERS\CDROM into your DOS directory either on the desktop, or with 
 COPY C:\DRIVERS\CDROM\HPC_CD.SYS c:\DOS\ 
at the DOS prompt, then and put a line in CONFIG.SYS similar to this:

  DEVICE=C:\DOS\HPC_CD.SYS /D:MSCD000
  
  Note that the /D:<name> means 'Devicename', not Drive D:, the drive letter
used is supplied automatically by DOS. Note that if you have a
LASTDRIVE=<letter> command then the letter must be high enough for all your
partitions, CDROM drives, network drives, etc. 
  You may also have to change the path, if you put the file somewhere other
than your DOS directory.

You should also copy MSCDEX.EXE to a suitable place, if you don't have it
already installed (check in your DOS directory) and include the line

  C:\DOS\MSCDEX /D:MSCD000

in your AUTOEXEC.BAT file. 

If using Windows 95
-------------------
The above instructions still apply, unless you have a Windows 95 installation
without DOS, in which case you will need to put the HPC_CD.SYS driver in a
different directory. We recommend C:\WINDOWS\COMMAND.

You will also need to create CONFIG.SYS & AUTOEXEC.BAT files in the
root directory C:\ if they don't already exist.



Error Messages from HPC_CD.SYS
==============================

ERROR! Invalid line in CONFIG.SYS

  Means some of the text following "DEVICE=HPC_CD.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 HPC CDROM services
       This driver needs !PC version 2.00 or later
       
  One of Two reasons:
  1) You are running HPC_CD.SYS on a version of !PC prior to v1.99. Versions
     before this must use A1CD.SYS
  2) 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. 
                                                 
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 CDFSDrives to 1.
