Issue
When installing OS2 on a machine with 4 gig or larger drives, the installation gives an error stating that it cannot find a partition large enough to install OS2. Also, Bus Mastering can cause the system to hang or cause the hard drive to pause for long periods of time.
Procedure
Updating OS2 to support hard disks larger than 4.3gb.
  1. Download from IBM's web-site a patch named "idedasd.exe". Expand this file to a directory.
  2. Make a backup copy of the OS2 diskette labeled "Diskette 1" (D1).
  3. Copy the new versions of IBM1S506.ADD and OS2DASD.DMD device driver files onto your D1 diskette.
  4. Add the statement SET COPYFROMFLOPPY=1 to the CONFIG.SYS on D1.
  5. Save the changes.
  6. Start the installation with the Installation Diskette.
  7. When you are prompted for Diskette 1, use the diskette you modified.
  8. Proceed with the installation.
  9. If during the installation process or when restarting your system, you lose connection to your hard disk or CD-ROM drive, make sure that the device driver statements are in the CONFIG.SYS file and the new versions of the IBM1S506.ADD and OS2DASD.DMD device drivers have been copied to the \OS2\BOOT\ directory. Use the date of the files to distinguish the newer versions. Bus Mastering causes the System to Hang or Hard Drive Hesitation, to disable Bus Mastering do the following: Edit the CONFIG.SYS file on Diskette 1 or the boot drive. Disable bus mastering by adding the parameter "/!BM" to the IBM1S506.ADD driver For example: BASEDEV=IBM1S506.ADD /A:0 /!BM /A:1 /!BM Save the changes and reboot.
