DESCRIPTION

When installing OS/2 Warp 4 from a Backpack CD-ROM, using the drivers 
that ship with the Backpack CD-ROM, an error message occurs during 
Diskette 2 of installation: "OS/2 is unable to operate hard drive or 
diskette drive."

This error occurs on any system using Backpack CD-ROM models 163550, or 
164550.

RESOLUTION

Obtain the latest drivers for the Backpack CD-ROM from the following 
location:

ftp://www.micro-solutions.com/software/backpack/cd_rom/os2_only

Download OS2CD204.EXE to a temporary directory. Change to this 
temporary directory, then type OS2CD204 to extract the files. 
BPCDOS2.ADD is the file needed for the installation.

Update the OS/2 installation diskettes as follows:

1. Make a DISKCOPY of OS/2 Warp 4 Installation Diskette 1.

2. Edit the CONFIG.SYS file on the diskcopy of Diskette 1. 

3. Add the following statement to the second group of BASEDEV 
   statements:

   BASEDEV=PBCDOS2.ADD
  
4. Add the statement SET COPYFROMFLOPPY=1 to the end of the CONFIG.SYS 
   file.
 
5. REM the BASEDEV statements not needed for the particular system: 

   * For non-Micro-Channel systems remark-out all IBM2* drivers.

   * For Micro-Channel systems, remark-out all IBM1* drivers.

6. Save and exit the CONFIG.SYS file. 

7. Delete the driver off of Diskette 1 that was remmed out in Step 5
   to make room for the backpack driver.

8. Since the installation looks for all of the files on Diskette 1 
   to copy to the hard disk even though they are not needed, the 
   following steps must be done:
 
   * If you delete IBM2SCSI.ADD, for instance, use a text editor to 
     save a file as IBM2SCSI.ADD.

   * Repeat this procedure for any file you delete from the diskcopy of 
     Diskette 1.

9. Restart the system with the OS/2 Warp 4 Installation Diskette,
   inserting the modified Diskette 1 when prompted for Diskette 1.
   Continue the installation.
