This file describes the process for installing the
BETA2 Windows95 protected mode CM-207 CDROM device driver.

THIS DRIVER HAS NOT BEEN FULLY TESTED! USE IT AT YOUR OWN RISK!!!

This driver acts as a replacement for the generic 
ATAPI driver developed by Microsoft which is not 
fully compatible with the CM-207. The only change 
this driver makes is to correct the problem that 
mutes CD audio playback. If you do not plan on using 
this feature, you do not need to install this driver.


***IMPORTANT***

The installation procedure described below assumes
the following:

1). Windows95 is fully installed and running PROPERLY on your system.
2). The CM-207 hardware installation is complete.
3). You are using an IDE hard drive as your boot device. If your boot 
drive is anything other than an IDE device, you will see only one
IDE/ESDI entry in the hard disk controllers section. This entry is
the one you should disable.


To install the driver;

1). Go to the Windows95 "Control Panel".

2). Run the "System" utility.

3). Select the "Device Manager" page.

4). Remove any older copies of the CM-207 device driver by
highlighting the device entry under "CDROM Controllers" and 
clicking "remove" at the bottom of the page.

5). Expand the "Hard disk controllers" entry by clicking on the
"+" sign in the box to the left of the entry. This should expand 
the entry to show two identical sub-entries called "Standard IDE/ESDI 
Hard Disk Controller".

6). Double click on the second entry to bring up the "Hard disk 
controller properties" window.

7). Select the "General" page.

8). UNCHECK the "Original Configuration (Current)" check box in 
the "Device usage" section. The check mark must be cleared from 
the check box.

9). Click on "OK" and "OK" again at the "System Properties" window.

10). Run the "Add New Hardware" utility.

11). Select "Next".

12). When asked if you would like Windows95 to search for your new 
hardware, select "NO" and then "Next".

13). Double click on "CDROM Controllers" and select "Have Disk".

14). Choose the path to the driver files and select "OK".

15). Double click on the "Philips CM-207 CDROM Controller" entry.

16). Click on "Next" in the "Resource Type/Setting" window.

17). Select "Finish".

18). When asked if you would like to shut down your system, choose
"Yes" and reboot the system.

The Windows95 CM-207 CDROM device driver should now be installed on 
your system. 

Known Problems;

1). The IDE/ESDI device driver supplied with Windows 95 will 
not work if a non-supported device is present on the slave 
position of the primary IDE port. This IDE/ESDI driver is 
incapable of selectively loading for a single device. If it 
can't control both devices on the port, it won't control either 
and will revert to a compatiblity mode driver (16-bit). What 
this means to the user is that, if your CM-207 is connected 
to the slave position of the primary IDE port, the primary 
IDE hard drive in the master position will run in 16 bit mode.
This is a Windows 95 problem and cannot be corrected without 
a modification to the operating system. This problem is easily 
avoided by running the CM-207 on the secondary IDE port.

2). Autoplay is not supported for either data or audio CD's.

3). CDROM drive transfer rate is heavily dependant on data 
buffering. In real mode (DOS, Windows 3.x) buffering was
performed, in part, by the device driver. In the Windows 95 
environment, the operating system has complete control over 
system resources and allocates a percentage of them to peripherals 
as it sees fit. If this percentage is too low, the result is 
poor CDROM performance at slower processor speeds.
