WRITING A CUSTOM FIRST-STAGE DRIVER 5.7. GENERATING A NEW FIRST STAGE CONTAINING THE CUSTOM DEVICE DRIVER Once you have written the custom device driver and changed the Bootstrap Loader Configuration files, you must generate a new first stage that includes the custom device driver. To do so, follow the steps below. 1. Compile or assemble the first-stage device initialization and device read procedures. For example, the following command assembles device read and device initialize procedures that are assumed to be in the file NEWDRV1.A86. - asm86 newdrvl.a86 object(newdrvl.obj) iRMX 8086/87/186 MACRO ASSEMBLER, V < > Copyright 1980, 1981, 1982, INTEL CORP. ASSEMBLY COMPLETED, NO ERRORS FOUND 2. Insert the object modules for the device read and the device initialize procedures into the object library of the Bootstrap Loader. This library is named BS 1.LIB and is in the directory /BSL. The following commands add the object modules generated in Step 1. - LIB86 iRMX 8086 LIBRARIAN V < > Copyright < > INTEL CORPORATION *add newdrv1.obj to jbs1.1ib *exit 3. Attach the directory containing your local copy of the Bootstrap Loader configuration files as the current default directory: - attachfile :home:mybsl :horne:rnybs1 attached AS :$: Bootstrap Loader 5-39
WRITING A CUSTOM FIRST-STAGE DRIVER 4. Generate a new first stage by invoking the SUBMIT file named BS1.CSD. Chapter 2 describes the details of the invocation. As an example, the following command assumes that you have chosen OCOOOH as the memory location of the first stage and OBCOOOH as the memory location of the second stage. - submit bsl(OCOOOH, OBCOOOH) This step assumes that you have made appropriate changes to the BSl.CSD file as described earlier in this chapter. The BS1.CSD file places the resulting located Bootstrap Loader in the file BS1. One thing to remember about this procedure is that because you added your device driver to the object library of the Bootstrap Loader, the device driver is automatically included in all future versions of the first stage created by BS1.CSD until BS1.LIB is upgraded in a future release of the iRMX Bootstrap Loader. 5-40 Bootstrap Loader
