1. OS/2 will install the BASEDEV= line at the beginning of the target
system's CONFIG.SYS file regardless of where the line is located in
that file on Diskette 1. You may need to rearrange the order in which
drivers appear in the
CONFIG.SYS file for the target system.
2. The driver for the host adapter to which the boot device is attached
must appear before all other
BASEDEV= drivers in the CONFIG.SYS file.
3. If you are installing both SDMS drivers and a host adapter containing
the LSI53C895A chip, the driver that will control the host adapter will
be the driver that appears first in the
CONFIG.SYS file. If one of the
two SDMS drivers is controlling the boot drive, that driver will also
control the LSI53C895A chip, since it must appear first in order for
the boot drive to be recognized.
Refer to the OS/2 documentation to fully understand this requirement.
7.4 Using Command Line Options
Your host adapter has a default configuration that consists of optimal
values for operation. You may decide to alter these default values if there
is a conflict between device settings or if you need to optimize system
performance.
Some values may be changed using the SCSI BIOS Configuration Utility
provided with some members of the LSI Logic family of host adapters.
Refer to your PCI Storage Device Management System SDMS 4.0 User’s
Guide for the availability and use of the SCSI BIOS Configuration Utility.
In addition, the SDMS OS/2 device drivers have several embedded
functions that can be accessed by using switches on the command line
in the
CONFIG.SYS file.
Values are applied in the following order:
•
Manufacturer's settings
•
SCSI BIOS Configuration Utility changes
•
Command line options
For the SYM8XX.ADD driver: When applying new values using the
command line options, changes in synchronous and wide negotiations
may only decrease speed or reduce width. Any changes that attempt to
increase speed or width are ignored.
