Installing a DR-UA124x ATAPI CD-ROM Drive and
Microsoft Windows 95

Overview/Problems

Under certain conditions, Windows 95 will not recognize the Pioneer DR-UA124x
ATAPI CD-ROM drive during boot-up.  The problem occurs when attempting to
install the DR-UA124x drive into a computer that is already using Windows 95.  If 
Windows 95 is installed into a computer already using a DR-UA124x, the boot-up 
problem should not occur.

Solution

At this time, Windows 95 does not support the DR-UA124x, so the simple,
one-time solution described below needs to be implemented.  Pioneer's CD-ROM 
ATAPI driver, ATAPI_CD.SYS, must be added to the system's CONFIG.SYS
file and MSCDEX.EXE (ver 2.24 or higher) must be executed in the
 AUTOEXEC.BAT file.

Note:  Some multimedia kit's have renamed the device driver from:

ATAPI_CD.SYS   to   PIONEER.SYS

1. The following line must be added in the CONFIG.SYS file:

       DEVICE=C:\PIONEER\ATAPI_CD /D:MSCD000 /S:xx

Example:

	DEVICE=C:\PIONEER\ATAPI_CD.SYS /D:MSCD000 /S:3

			or

	DEVICE=C:\DIAMOND\PIONEER.SYS /D:MSCD000 /S:3

Note:  Directory where "ATAPT_CD.SYS" may be different, if so
	change path to correct directory path.

Where xx value depends on the DR-UA124x mode (master or slave) and
which IDE port is connected.

xx = 0  : Primary IDE Master
xx = 1  : Primary IDE Slave
xx = 2  : Secondary IDE Master
xx = 3  : Secondary IDE Slave


2. The following line must be in the AUTOEXEC.BAT file:

      C:\WINDOWS\COMMAND|MSCDEX.EXE /D:MSCD000


After making the above changes, the system needs to be rebooted and
Windows 95 should recognize and access data on the Pioneer's 
DR-UA124x CD-ROM Drive
