SYMPTOMS
========

If EMM386 is unable to find 64 kilobytes (K) of contiguous memory in the upper
memory area, it cannot create an expanded memory page frame and displays the
following error message:

  Unable to create page frame

WORKAROUND
==========

If do not want expanded memory for your system, you can substitute the NOEMS
switch for the RAM switch in your EMM386 DEVICE command in CONFIG.SYS.

However, if you do want expanded memory, you can try establishing a page frame in
a portion of the upper memory area not normally used by EMM386. You can try
putting the page frame in the E000 memory block by following these steps:

Note: Do not try the following procedure if you have an IBM model PS/2 computer.

1. To create a startup floppy disk, insert a floppy disk in drive A and type the
  following:

  " sys c: a:
  copy c:\config.sys a:
  copy c:\autoexec.bat a: " (without the quotation marks)

  NOTE: If you are using MS-DOS 4.x you must also copy COMMAND.COM to drive a.
  For example, type "copy c:\command.com a:" (without the quotation marks) at
  the MS-DOS command prompt and then press ENTER.

2. Edit your CONFIG.SYS file and modify the EMM386 DEVICE command to look like
  this:

  device=c:\dos\emm386 m9 ram

3. Remove the floppy disk from drive A and restart your computer.

Your computer should restart normally, and you should no longer receive the page
frame error message. If you have problems starting your computer, insert the
startup floppy in drive A, restart your computer and copy the CONFIG.SYS file
from drive A to drive C.
