DR-UA124X Install Manual

1. Drive Unit connection

1.1 Adding the CD-ROM to a configuration with one IDE Hard Disk 

Set DR-UA124X to SL(Slave mode) by setting a jumper on the rear 
side.
Make sure the Hard Disk is set to IDE Master mode (Check your 
Hard Disk's documentation for details)

1.2 CD-ROM only connection to IDE card

MA(Master mode) or SL(Slave mode) are both valid settings
In some case only SL mode will work reliably because of the 
system BIOS.

2. OS specific information

Run the installation program (INSTALL.EXE), and this will perform the
following :-

2.1 MS-DOS

If your OS is MS-DOS ( or IBM PC-DOS) , then perform the following  
steps :

2.1.1 copy from Floppy disk

Copy the file ATAPI_CD.SYS to your Hard disk

2.1.2 Modify CONFIG.SYS

After Connecting the CD-ROM drive and copying the device driver  
to the Hard Disk. Add the following line to CONFIG.SYS :

 DEVICE=C:\ATAPI_CD.SYS
 LASTDRIVE=Z

Valid options for this device driver are listed below. In most cases 
however,  you don't need to specify any options.
In case no options are specified, the driver will search for the DR-
UA124X automatically.

If the device driver loads successfully but the CD-ROM can't be 
accessed, you must specify the LASTDRIVE line in CONFIG.SYS.

Setting device driver options :

 e.g. :

	DEVICE=C:\ATAPI_CD.SYS /S:1 /D:MSCD001

[Option]
	/S:x   ------> CD-ROM Drive ID.
	This determines the setting of the drive to Master or Slave 
	and the connection to the Primary or Secondary channel.
   
		x =     0: Master Drive on Primary IDE Channel
			1: Slave Drive on Primary IDE Channel
			2: Master Drive on Secondary IDE Channel
			3: Slave Drive on Secondary IDE Channel

	/D: *******    -->    CD-ROM Device name
		e.g.:   /D:PIONEER

	If you do not specify this option, a default CD-ROM Device 
	name is used : "MSCD001".

In case you copied the device driver to a sub-directory, specify the 
FULL PATH name in the "DEVICE=..... " line in CONFIG.SYS.

2.1.3  Modify AUTOEXEC.BAT

 Add  the following line to AUTOEXEC.BAT.

 e.g. :
	MSCDEX.EXE  /D:PIONEER

Make sure the  CD-ROM Device name is same as in CONFIG.SYS 
	"/D : PIONEER"
(In case you didn't specify this option in CONFIG.SYS, specify : 
"/D:MSCD001")

2.2 MS-Windows

In case the DR-UA124X is connected to the Primary IDE Channel 
and the IDE Hard Disk is set to Master mode, the 32bitDiskAccess 
parameter in the Windows SYSTEM.INI file should set to OFF.  
This can be achieved in two ways : 

	Double-click Control Panels, then double-click 386Enhanced 
	and uncheck the 32bitDiskAccess checkbox. Click OK and 
	restart.

	Experienced users can edit the SYSTEM.INI file in the 
	\Windows directory :

	(Original)              32bitDiskAccess=ON
	(Change to)     32bitDiskAccess=OFF

2.3 Windows NT Ver 3.5

When Installing Windows NT after connecting the DR-UA124X to 
the primary IDE Channel in Slave mode, the CD-ROM drive will be 
automatically recognised.

If you are adding the DR-UA124X to an existing Windows NT 
installation, refer to the Windows NT documentation. (The DR-
UA124X can be installed as ATAPI device)

2.4 OS/2 Warp Ver. 3.0

When installing OS/2 Warp after connecting the DR-UA124X to the 
primary IDE Channel in Slave mode, choose "Other IDE CD-ROM" 
from the CD-ROM Device list.

If you are adding the DR-UA124X to an existing OS/2 Warp 
installation, choose selective install and select "Other IDE CD-ROM" 
from the CD-ROM Device list.

2.5 Miscellaneous

For other Operating Systems or when developing test programs, 
please refer to the following documents :

*DRM/DR-U series SCSI-2 command manual (Pioneer document)
*DR-UA series ATA command specification (Pioneer document)
*ATA Packet Interface for CD-ROM
     (SFF-8020 Rev 1.2)
*ANSI X3T9.2 SCSI2 Rev 10L
*ANSI X3T9.2 ATA2 948D

Copying & distribution of this device driver is prohibited.

Troubleshooting hints :

When setting DR-UA124X in Master mode on the primary IDE 
channel, in some cases powering on the PC will not work. In this 
case press the reset button to retry and it should work.
