    Abstract:  IOS ERROR DURING INITIAL BOOT ON IBM PC6588-12U

  SYMPTOM:
  During the initial boot-up on IBM PC6588-12U systems preloaded
  with Windows95, the user may see an error message or hang
  condition similar to the following examples:

    A "Cannot write to registry file, disk full" error message
    An IOS Error: "Error: An I/O subsystem driver failed to load"
    A hang condition at the "Setting Up Hardware" window
    A hang condition at the main Windows95 logo screen
    A Windows Protection Error message

  PROBLEM ISOLATION AIDS:
  NOTE: If the system HAS NOT been powered on for the first time,
        perform Steps 2-7 in STEP 1 below to prevent these errors
        from occurring.

  A limited number of 6588-12U systems will experience problems
  upon the initial boot of the Windows95 preload. Those systems
  that manifest problems can be recovered by following the fix
  procedures below.

  FIX:
  STEP 1:
  1. Power off the system.
  2. Remove any installed adapter cards.
  3. Power the system back on and press F1 for the Setup Utility.
  4. Highlight "Start Options" and press <Enter>.
  5. Highlight "Configuration Mode" then use the arrow keys to
     select "Use BIOS Setup" and press <Enter>.
  6. Highlight "Exit Setup" and press <Enter>.
  7. Highlight "Yes, save and exit the Setup Utility" and press
     <Enter>.
  8. Optional: If the Microsoft Windows95 Startup Menu Option is
     displayed when rebooting after following this procedure,
     select option "#1. Normal."

  Some 6588-12U systems that experienced problems on the initial
  boot of Windows95 have Device Manager conflicts. Yellow caution
  indicators will appear underneath the "Sound, Video, and Game
  Controllers" section beside the "Creative Labs Sound Blaster
  Pro" and the "Crystal PnP Audio System CODEC" devices. Those
  systems can be correctly configured by following the procedure
  below.

  STEP 2:
   1. From the Windows95 desktop, right click the "My Computer"
      icon and select "Properties."
   2. From the System Properties Menu, select the "Device Manager"
      tab.
   3. Highlight the "Creative Labs Sound Blaster Pro" device
      underneath  the "Sound, video, and game controllers section
      and select Remove.
   4. Select Close from the System Properties Window.
   5. From the Taskbar select Start, then select Shutdown, then
      select "Restart the Computer?" and choose Yes.
   6. As the system is rebooting, press F1 for the Setup
      Utility.
   7. Highlight "Start Options" and press <Enter>.
   8. Highlight "Configuration Mode" then use the arrow keys to
      select "Use PNP OS" and press <Enter>.
   9. Press <Esc>, then highlight "Exit Setup" and press <Enter>.
  10. Highlight "Yes, save and exit the Setup Utility" and press
      <Enter>.
  11. After the Windows95 desktop is displayed, select Start,
      then select Shutdown, then select "Restart the Computer?"
      and choose Yes.
  12. As the system is rebooting, press F1 for the Setup
      Utility.
  13. Highlight "Start Options" and press <Enter>.
  14. *Highlight "Configuration Mode" then use the arrow keys
      to select "Use BIOS Setup" and press <Enter>.
  15. Press <Esc>, then highlight "Exit Setup" and press <Enter>.
  16. Highlight "Yes, save and exit the Setup Utility" and press
      <Enter>.

  *Configuration Mode is set back to "Use BIOS Setup" in order
   to maintain compatability with system management software.

  If at anytime during this procedure Windows95 will not allow
  the steps to be followed because of hang conditions or other
  error messages, contact the IBM PC HelpCenter at
