IBM OS/2 2.x / 3.x IDE CD driver for IDE CDROM drives
February 16, 1995
This package contains the drivers for IDE CDROM drives
PJ16105 Trap 0003 on 4MB machines during Install
PJ16058 Non-ATAPI Compliant fixes
This package also contains several modifications to the driver
which allow certain IDE CDROMs with not 100% compliant HW to
work with OS/2.
You MUST use these NEW files to replace the existing copies supplied
by whatever version of OS/2 you are using.
All four system files must be replaced (or added):
IBMIDECD.FLT <- Not in versions of OS/2 prior to Warp 3.0, add
This ATAPI.ZIP file is NEWER than the files on the OS/2 WARP FULL PACK...
Installation if OS/2 is already installed on your fixed disk
1. you must run Selective Install to install the files for the OS/2 CD-ROM
Device Manager and OS/2 CD-ROM File System.
a. Open the OS/2 System folder on the desktop.
b. Open the System Setup folder.
c. Open Selective Install
d. Select the CD-ROM Device Support check box
e. Select OK
f. Scroll to the bottom of the CD-ROM device list table and
select the choice OTHER (OS/2 2.1) or Non-listed IDE CD-ROM (WARP)
g. Select OK
h. Select the OK push button to proceed from the System Configuration
screen to the OS/2 Setup and Installation window
i. Select Install
j. When prompted to do so, insert the numbered installation diskette.
2. Copy the files provided in this package OVER those installed in step 1,
to their proper location on your system. On Warp this is OS2BOOT.
Check by doing a 'DIR IBM1S506.ADD /S' on your system <== DIR command
3. IDE CD ROMs that adhere to the ATAPI specification of February 1994
will be detected automatically if they are configured on the Primary or
Secondary IDE channel. If your IDE channel is not the primary or secondary,
or if your IDE channel is not using the default io ports and IRQs, do a
'HELP IBM1S506.ADD' at an OS/2 command prompt to get detailed information
on changing or adding channels.
4. Some drives do not respond to an ATAPI command from the February Spec.
These drives can not be auto detected and require an additional parameter
on the IBM1S506.ADD line in config.sys. The NEC 260 drive, for example,
requires this additional parameter.
BASEDEV=IBM1S506.ADD /A:x /U:y /ATAPI
where x is the adapter number and y is the unit number.
Which IDE drive connector on your adapter contains the cable
that the NEC 260 IDE drive is connected to
IF you have only one IDE controller, this is Adapter 0, /A:0
IF you have TWO IDE controllers, and the IDE CDROM is connected to
the second controller cable, this is Adapter 1, /A:1
The Enhanced IDE specifications allow for FOUR adapters, so
/A: COULD also be 2 or 3 in your system.
Each IDE controller can drive up to TWO drives. If the CD drive
is jumpered as the Master then this is unit 0, /U:0 otherwise it
is unit 1, /U:1 It is not possible to have a device configured as
Slave without a Master on the same controller.
/atapi or /ATAPI
This informs the IBM1S506.ADD driver that this unit (/a: /u:) is an
ATAPI (IDE attached) CDROM drive...
Editing your config.sys...
locate the BASEDEV=IBM1S506.ADD line
If you have NO parameters on this line, then ADD the
parms as defined above, /A:? and /U:?
an example line with the CD as slave on controller 1
BASEDEV=IBM1S506.add /A:0 /U:1 /ATAPI
IF you ALREADY have parms, and have a /A:? parm already, make sure
to add JUST the /U:? parm for that adapter.
5. IF you are using OS/2 2.11 or earlier, you will need to add the following
config.sys statement. (If you have WARP, choosing 'NON listed IDE CDROM'
will cause this line to be placed in config.sys automatically)
6. Shut down and restart your system
Installation if OS/2 is NOT already installed on your fixed disk
1. create the CD install disk 1 from the OS/2 CDROM
2. copy the files supplied here OVER the ones on disk 1.
3. If you have a NEC 260 IDE CDROM drive, edit the config.sys on disk 1
and modify the BASEDEV=IBM1S506.ADD line as described above
(adding the /A & /U parms)
3a. If you are using OS/2 2.11 or earlier, add the following statement
to config.sys and copy the associated file onto disk 1.
3b. If you are using OS/2 WARP, add the following statement to the config.sys
on the DISKETTE 1:
4. Boot the installation disk and disk 1 and proceed thru
installation phase 1.
5. (If you are using OS/2 WARP, skip to step 7)
Because the installation program uses copies of these files
from a packed file on the installation diskettes, the
UPDATED drivers you copied in step 2 are overlayed with
the older ones on your hard disk. You MUST manually
When you are asked to reboot to continue the installation,
insert the installation disk and press Ctrl-Alt-Del, then through disk 1
to the install panel. Press F3 to get to a command line. Go to the
installation drive (wherever you installed OS/2). You will need to clear
the read-only attribute on the IBM1S506.ADD file. Do this by typing:
(OS/2 2.1 & 2.11)
/os2/attrib -r os2ibm1s506.add
Copy the updated files (OS2CDROM.DMD, IBM1S506.ADD, and IBMIDECD.FLT from
disk 1 to the proper location on the install partition)
6. type EXIT from the command line
7. remove the diskette from A: and reboot
8. Complete the rest of install
