This BETA release of the Windows 95 device driver can control the Philips CM-205 multi-session, and CM-206 CDROM drives. This release of the driver has not been fully tested and may not function properly. For this reason, Philips LMS requires that you use this driver AT YOUR OWN RISK!. If you would rather wait for a fully tested driver, we expect to complete any changes and release the final version of this driver in January 1996. To install the driver, use the following procedure: 1) From the Windows 95 Control Panel: * Select the 'Add New Hardware' option. * You DO NOT want Windows to auto detect the hardware. * Add a new CDROM controller. * With the setup diskette in drive A, select the HAVE DISK option. The system may need to be re-booted afterwards, however, the operating system should be able to detect the new changes without re-booting. _______________________________________________________________________________ Setting Interrupt Jumpers: The driver will utilize a 'Polling' method unless directed to use Interrupts by the Registry Entry for the device. Polling is fine for casual usage. However, to properly run applications which are CDROM intensive, interrupts must be used. Use the following procedure to enable interrupts for the CDROM device(s): 1) Set the interrupt jumper on the host adapter card to the desired level. 2) From a Windows 95 MS-DOS prompt, run the Registry Editor (REGEDIT) and modify the Registry Entry under the Philips CDROM device as follows: HKEY_LOCAL_MACHINE\SYSTEM\CURRENT_CONTROL_SET\SERVICES\CLASS\ADAPTER \0000\AdapterSettings 3) Edit the AdapterSettings String using the following syntax: IRQx=3 where x is the device number 0, 1, or 2. If you have one Philips CDROM drive, use device number 0. The Registry Tree Entry will look something like this for a single host adapter set to IRQ 15: HKEY_LOCAL_MACHINE\SYSTEM\CURRENT_CONTROL_SET\SERVICES\CLASS\ADAPTER \0000\AdapterSettings:IRQ0=15 4) Windows 95 has a performance option that can be set from the Control Panel 'System' icon. This option allows you to optimize Cdrom access for a dual speed (2X) drive such as the CM206. 5) The system will need to be rebooted for the changes to take effect.
