=======================================================================
  SYS0038 during Installation because of Joshi/Yoshi Virus - OS/2 Warp
=======================================================================

Please Read Entire Document for Full Explanation of Procedure
-------------------------------------------------------------

DESCRIPTION

During installation of OS/2 Warp 3.0, the system locks up, and the 
following message is received:

   SYS0038: System cannot find the ... device.

The system also locks up during the first restart. You might hear a 
beep when you insert Diskette 7 after the restart.

RESOLUTION

The problem is caused by the Joshi or Yoshi virus. On systems infected 
with the Joshi virus, installation fails. You have to remove the files 
infected by the virus.

When dealing with the Joshi virus, always turn the system off before 
restarting. If you press Ctrl+Alt+Del, the Joshi virus remains in 
control.

If the Installation Diskette is write-enabled, it becomes infected if 
Joshi is active in memory. If the Installation Diskette is in drive A 
and you start installation by pressing Ctrl+Alt+Del, the virus also 
intercepts reads during startup (MBR on hard disk; diskette boot record 
on diskettes) and presents the original, uninfected boot record to the 
program that is reading the boot record. This works fine under DOS, but 
when OS/2 is started from the Installation Diskette, when OS/2 gets 
control, the virus cannot intercept reads of the boot record, so any 
program that looks at the boot record sees the Joshi virus.

If the Installation program is looking for a serial number or name 
field in the boot record of the diskette, the same field might be 
different in the boot record of a diskette infected with the Joshi 
virus.

If you have a virus checker, use an uninfected system and check all 
installation diskettes for viruses.

You can order a virus checker from IBM by calling 1-800-551-3579.
