Adding SDL Tools Support for New Devices

SBCSCSI/D1 E-17

3. Edit "file.c", altering all parameters required to support the new device as

required. Refer to the SCSI-2, SCSI Driver Library, and manufacturer's

speciÞcations for initialization parameters.

4. If a "MakeÞle" is being used, add "file.c" and "file.o" to the SOURCES and

OBJECTS lists, as well as the compiler invocation instructions which build

"file.o".

5. From the above table, locate the appropriate array for the device type

being added, in the Þle "globals.c". Add the name of the new device to the

array. If more than MAX_DEVICES (deÞned in "t167.h") entries appear in

the array declaration, the compiler generates an error message. Either the

value of MAX_DEVICES must then be changed, or support for an existing

device deleted.
