OSCINHDS - ERROR DURING OS/2 WARP INSTALLATION: UNABLE TO OPERATE
HARD DISK OR DISKETTE DRIVE
02/09/96
=======================================================================
Error during OS/2 Warp Installation: Unable to Operate
Hard Disk or Diskette Drive
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
During installation of OS/2 Warp, the following error message is
received:
OS/2 is unable to operate the hard disk or diskette drive.
RESOLUTION
Note: Make sure you have a backup of any file you intend to change.
* There could be an incompatibility between OS/2 and the system
diskette-drive or hard-disk-drive controller:
1. Edit the CONFIG.SYS file on the diskette or hard disk from where
you are starting OS/2.
2. Find the statements with BASEDEV=filename.ADD and change them to:
REM BASEDEV=filename.ADD
3. Be sure the following statements are in the file (x is 1 for
non-Micro-Channel systems, and 2 for Micro Channel systems):
BASEDEV=IBMxFLPY.ADD
BASEDEV=IBMINT13.I13
BASEDEV=OS2DASD.DMD
BASEDEV=OS2SCSI.DMD
Note: OS2DASD.DMD is needed for IDE and SCSI hard disks.
OS2SCSI.DMD is needed for SCSI hard disks only.
* A diskette-drive or hard-disk-drive controller might have an
additional device, such as a tape backup, scanner, network card, or
modem, attached to it:
Disconnect the additional devices, if possible.
* An interrupt request (IRQ) level conflict might exist between the
diskette-drive or hard-disk-drive controller and other installed
devices:
Change IRQ levels to eliminate conflicts.
* The hard-disk partition where you are installing OS/2 is compressed
with a DOS data-compression program:
Use the data-compression program to uncompress the partition; then
restart the installation procedure.
* Traps usually are symptoms of software-related problems. When you
have reviewed software symptoms, consider a hardware cause relating
to caches and memory such as:
- If the computer has an 80486 microprocessor, it might require
faster RAM chips (60 ns or 70 ns).
- There might be a problem with the external (level-2) CPU memory
cache or main memory system on ISA or EISA systems. From setup or
diagnostics diskettes, or from the built-in BIOS Setup program,
try disabling all shadow RAM and external (level-2) CPU memory
cache.
If problems persist during the installation of OS/2 after trying
this step, turn off the turbo switch, if available, disable caching
during installation, and try again.
