’s device drivers support command-line switches
to optimize driver performance. Device drivers normally require no additonal
information to work effectively, but for your system or applications you might need
to turn certain features ON or OFF. In the CONFIG.SYS file, use the following
standard command format to modify the device driver’s switches:
BASEDEV = INIA100.ADD [driver-config option]
The “driver-config options” are:
/V Verbose Mode provides detailed information about the driver on
the system command line when the driver is initialized
/!V Non-Verbose Mode (default)
/ET Driver assumes that all targets have more than one LUN (logical
unit number)
/!ET Driver assumes that all targets only have LUN 0 (default)
/T:hhhh Target-enable mask word (default: FFFF hex, scan all targets)
The range for “hhhh” is from 0000 hex (disable all targets) to
FFFF hex (scan all targets).
This is a powerful and complex option by which you can have the
driver control only certain selected devices. Each of the four hex
characters stands for four of the SCSI IDs, each of which has its own
corresponding bit for which “1” = control enabled, “0” = control
disabled. For example, if you wanted the driver to be able to
control all of the devices on the bus except a CD-ROM drive on
ID 3, a tape drive on ID 6, and scanners on IDs 9 and 10, you would
enter the command phrase “/T:F9B7”:
IDs: 15 14 13 12 11 10 9876543210
Binary: 1 1 1 1100110110111

/B:b,dd Scan PCI DEVICE #dd on PCI BUS #b
The range for “b” is from 0 to 7 decimal.
The range for “dd” is from 0 to 20 decimal.
