OS/2 Warp Install Fails on First Restart in System with Two SCSI 
Controllers

DESCRIPTION

During installation of OS/2 Warp 4 on a system with two SCSI 
controllers, a device driver error, system lock up, or a different 
error message occurs when the system restarts from the hard disk.

RESOLUTION

If more than one SCSI adapter is present, a BASEDEV statement for each 
adapter normally is added to the CONFIG.SYS file. The OS/2 installation 
does not consider which SCSI adapter is being used for installation 
when it chooses the order of the BASEDEV statements in the CONFIG.SYS 
file.

The device drivers for the adapters are loaded in the order that their 
BASEDEV statements appear in the CONFIG.SYS file. The BASEDEV statement 
for the driver of the SCSI adapter where OS/2 is being installed must 
be placed before the BASEDEV statement for the other SCSI adapter. 
Chances are that the order of the BASEDEV statements is backwards. OS/2 
assumes that the adapter for which the first BASEDEV statement it finds 
in the CONFIG.SYS is controlling the hard disk that OS/2 is being 
installed on.

To resolve the problem, reverse the order of the BASEDEV statements in 
the CONFIG.SYS file for the SCSI device drivers:

1. Restart the system with the OS/2 Warp 4 Installation Diskette,
   inserting Diskettes 1 and 2 when prompted.

2. Press F3 at the Welcome screen to escape to a command prompt.

3. Type COPY C:\CONFIG.SYS C:\CONFIG.BAD, then press Enter,
   to make a backup copy of CONFIG.SYS (where C: is the OS/2
   installation drive).

4. Type TEDIT C:\CONFIG.SYS, then press Enter.

5. Press Esc. Scroll through the file to look for BASEDEV statements.

6. Reverse the order of the SCSI device BASEDEV statements, 
   then press F4 to save and exit the file.

7. Remove the diskette from drive A: and restart the system.
