+ ATAPI driver changes: (Eesox: Mark Watson)
+
+------------------------------------------------------------------------------------------------
+ 0.02    27-Sep-94         First version given to Acorn (Martin Neville-Smith)
+------------------------------------------------------------------------------------------------
+ 0.03    12-Oct-94         Added:   AudioPause.
+                                    Checks on startup for ATAPI, CD-ROM and removable.
+                                    Takes into account slow devices that need a pause after
+                                      sending a command, before checking INTRQ or DRQ.
+                                    Writing 16 bit value now writes 2 copies (high and low)
+                                      for RISC PC.
+                           Removed: Module_CheckForATAPIDrive instead does identify drive.
+                           Fixed:   On initialisation accidently stored at location 0  !!!
+------------------------------------------------------------------------------------------------
+ 0.04    23-Oct-94         Fixed:   EnquireDataMode for Sony CDU55E.
+                           Fixed:   Read data for Sony CDU55E.
+                           Fixed:   Now works with PhotoCD and mode 2 form 1, not m1 form 2
+------------------------------------------------------------------------------------------------
+ 0.05    09-Nov-94         Added:   On initialisation if there are no drives found then module
+                                    errors and dies with 'No CD-ROM drive present'.
+------------------------------------------------------------------------------------------------
+ 0.06    10-Nov-94         Added:   Locking and unlocking of IDE registers
+------------------------------------------------------------------------------------------------
+ 1.00    10-Nov-94        NO CHANGES - Version number brought up to release
+------------------------------------------------------------------------------------------------
+ 1.01    05-Dec-94         Added:   SWI to find out number of ATAPI drives found.
+                           Changed: Method of dying if no drives found changed from using
+                                    OS_GenerateError to AddCallBack then *RMKill.  Nice huh.
+                                     There must be a better way than this ?
+                           Removed: CompareStrings routine as it wasn't used
+------------------------------------------------------------------------------------------------
+ 1.02    18-Dec-94         Added:   Implemented ReadUserData
+                                    GetAudioParms (volume level)
+                                    SetAudioParms (volume level)
+------------------------------------------------------------------------------------------------
+
+ 1.02 = 1.05 in SrcFiler (AMcC) 02-Feb-95
+

Doc/!Notes

+Notes:
+
+1. Disc busy light indicator:
+
+   Using Read CD (&BE) command causes both hard disc and CD-ROM drive lights to come on.
+   This happens on the Panasonic drive, don't know about Sony.  Read &A8 only turns on the
+   CD-ROM drive light as expected.
+

Doc/!ReadMe

+
+10-Nov-94
+
+ Dear Martin,
+             please find version 1.00 of ATAPI driver on this disc.
+
+
+
+Drives tested with       Noticed
+------------------       -------
+Sony CDU55E BC           Works fine with audio, mode 1 and mode 2 form 1 (PhotoCD)
+                         Doesn't work with mode 2 form 2 - CD-I green/white book discs
+
+Panasonic CR-571         Works fine with audio, mode 1, mode 2 form 1, green/white book
+                         Seems a bit pushed to play Replay in mode 28 on A5000.  Just copes.
+
+
+  Basically, I'd go with the Panasonic drive - especially if it's cheaper.  I would advise
+testing it out playing MPEG videos as these may be heavy on processor power.  It's probably
+fine, but it's the one thing I can't test (as it is v. important to you guys).
+
+
+
+ Mark
+
+ps  I've still got a 40MB harddisc of yours and an 8MB A5000.  Do you want them back ? (ho-ho)

Doc/ADFS/irq

+Interrupts
+==========
+
+There are several conditions that must exist before the IDE driver receives
+an interrupt:
+
+   a. the controller must assert IRQ14;
+   b. IEN must be enabled in the controller digital output register;
+   c. the interrupt must be enabled in IOC (or on the podule);
+   d. the CPU must have IRQs enabled.
+
+Condition (b) is always true except during the handling of an interrupt from
+the controller. In order to maintain a low interrupt latency, the driver
+enables CPU IRQs (d) in its interrupt handler. If the interrupt were not
+masked during this time, the controller could interrupt the interrupt
+handler which is not designed to be reentrant. (As an example, consider a
+multi-sector read: after the interrupt for the first sector, the driver
+reads the sector data and the controller interrupts again immediately
+because it has cached the next sector.) Option (b) has been chosen instead
+of (c) because it requires fewer instructions. Interrupts *are* disabled in
+IOC (or on the podule) when no IDE command is active.

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
