OSIN2SCS - OS/2 WARP INSTALL FAILS ON FIRST RESTART IN SYSTEM WITH TWO
SCSI CONTROLLERS
11/11/96
=======================================================================
OS/2 Warp Install Fails on First Restart in System with Two SCSI
Controllers
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
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.
