****************************************************************************

This driver is supplied with your IBM system for use on WARP V3.x and WARP
V4.x systems. It replaces the standard IDE drivers on your system and has
the same driver names. You should back up your current versions should you
encounter a problem that requires you to return to that previous version.
THESE DRIVERS ARE NOT SUPPORTED ON VERSIONS PRIOR TO WARP 3.0.

This driver includes support for the Intel 82801 chipset, and
ATA-66 Ultra DMA.


****************************************************************************
*       Installation                                                       *
****************************************************************************

The Installation of these drivers require you to copy them to the OS/2 boot
partition of your hard drive. You should be careful to retain a backup copy
of your current version of these drivers. The drivers can be installed in
two locations.  This procedure requires that you already have IDE support
installed on OS/2.

Method 1:

(1) Locate the current OS/2 boot patition on your hard drive. This is usually
    the C: drive and will contain the OS2 sub-directory.

(2) Copy the driver files into the root directory of your hard drive.
    There are two drivers involved, IBM1S506.ADD and IBMIDECD.FLT.

    Their function is:

    IBM1S506.ADD  :  base driver for IDE/EIDE/ATAPI devices (should always
                     be copied)
    IBMIDECD.FLT  :  CD-ROM driver support. (If using this driver, then the IDE
                     driver above, IBM1S506.ADD is required.).

    The drivers if found in the root directory are discovered and loaded
    prior to discovery in the \OS2\BOOT sub-directory.


(3) There should already be entries in the config.sys file, and you should
    reboot your system to load the new drivers.



Method 2:

(1) Locate the current drivers on your OS/2 hard drive. You can use the
    following command :

        dir \ibm1s506.add /s

    The command will show you the sub-directory on your hard drive where
    the driver may be updated. (Remember to make a backup copy of your
    old driver.)

(2) Copy the driver files onto your hard drive in the sub-directory where
    the previous version was found. There are two drivers involved. There
    function is :

    IBM1S506.ADD  :  base driver for IDE/EIDE/ATAPI devices (should always
                     be copied)
    IBMIDECD.FLT  :  CD-ROM driver support. (If using this driver, then the IDE
                     driver above, IBM1S506.ADD is required.).

(3) The entries should already be in config.sys, and you should reboot your
    system to load the new drivers.

*       UnInstallation                                                     *
****************************************************************************
To uninstall these drivers, you should copy the previously saved copies of
these files, IBM1S506.ADD and IBMIDECD.FLT to the directory where you had
copied the new files.


****************************************************************************
*       Usage                                                              *
****************************************************************************

These drivers replace standard drivers of your earlier version of WARP.  The
CDROM driver, IBMIDECD.FLT does not need to be installed unless your system
contains a CDROM drive.

These drivers provide ATA-66 Ultra DMA support.  This support includes the
support of the Intel 82801 chipset and the ATA-66 Ultra DMA drives as well.

You will need to check the drivers after installation of any service packs,
fixpaks and\or CDROM support diskettes. These installation programs may
update drivers with prior versions of these drivers. If you use installation
method 2, you should verify that older versions of these drivers are not
placed in the root directory of your OS/2 drive. Drivers located in the root
will be discovered and loaded at boot time rather than the versions located
in the \OS2\BOOT directory.
