   INTCE virus exploits a BUG in DOS which prevents a Clean DOS diskette
from being booted on the infected system.

   In order to clean the cause of the DOS bug (which is a modified second
partition record on the infected system), a routine must be run before DOS
is loaded.

   The simplest way to do this would be booting a 'fixup' diskette and
this is what this standalone will do, it will create that 'fixup' diskette
for you.

  Upon completion, the second partition will be removed.   You can proceed
with damage control after you remove the bug and remove the virus from
infected programs.



There are3 files in this package:
   A boot sector to be written to a diskette.
	 C_INTCE.BOO
   The BAT file will wite the 'fixup' boot sector.
	 CLEANPAR.BAT
   This 'readme' file.
	 INTCE.TXT


If you don't understand any of the following commands, find
someone to help you.

1 You will create the 'fixup' diskette on a CLEAN DOS system.
  Use a DOS prompt to assure you perform the correct commands.

2 The DEBUG program should be available on this system.

3 Copy the files from this package to a diskette that you will
  be converting to the 'fixup' diskette.

4 Insert the diskette into the A: drive of the CLEAN DOS system.

5 At the command prompt, change directory to the A:
   (enter A: at the DOS prompt, this will make A: your current directory)

6 At the (now) A: prompt, enter CLEANPAR.
   This will cause DEBUG to write the "C_INTCE.BOO" file to the
   boot sector of the 'fixup' diskette in the A: drive.
  When finished, remove the diskette and slide the 'write protect' tab on!

7 Turn off the power to the Infected System and place this 'fixup'
  diskette into its A: drive.

8 Turn on the power to the Infected System, go into CMOS (usually via
  DEL or whatever instruction BIOS tells you at power on time)
  and ASSURE THAT YOU ARE BOOTING FROM THE A: DRIVE!!
  (usually you will see either A:/C:  or C:/A: as the 'boot sequence'
   be sure it is A:/C:)

9 When the 'fixup' boot runs on the infected system,  it will wipe
  out the second (buggy values) partition that the virus left for
  DOS to hang on.
  Upon completion, the 'fixup' will cause the BIOS message:
    "NO ROM BASIC .." Error message to appear on your screen.
  Turn off the power. Remove the 'fixup' diskette.

  At this point you should insert a CLEAN DOS Diskette and turn on
  the power.   DOS should now start.

10  Run scan with the /clean option.
