+@table @code
+@item pretasking_hook
+is the address of the user provided routine which is invoked
+once RTEMS APIs are initialized.  This routine will be invoked
+before any system tasks are created.  Interrupts are disabled.
+This field may be NULL to indicate that the hook is not utilized.
+
+@item predriver_hook
+is the address of the user provided
+routine that is invoked immediately before the
+the device drivers and MPCI are initialized. RTEMS
+initialization is complete but interrupts and tasking are disabled.
+This field may be NULL to indicate that the hook is not utilized.
+
+@item postdriver_hook
+is the address of the user provided
+routine that is invoked immediately after the
+the device drivers and MPCI are initialized. RTEMS
+initialization is complete but interrupts and tasking are disabled.
+This field may be NULL to indicate that the hook is not utilized.
+
+@item idle_task
+is the address of the optional user
+provided routine which is used as the system's IDLE task.  If
+this field is not NULL, then the RTEMS default IDLE task is not
+used.  This field may be NULL to indicate that the default IDLE
+is to be used.
+
+@item do_zero_of_workspace
+indicates whether RTEMS should
+zero the Workspace as part of its initialization.  If set to
+TRUE, the Workspace is zeroed.  Otherwise, it is not.
+
+@item idle_task_stack_size
+is the size of the RTEMS idle task stack in bytes.
+If this number is less than MINIMUM_STACK_SIZE, then the
+idle task's stack will be MINIMUM_STACK_SIZE in byte.
+
+@item interrupt_stack_size
+is the size of the RTEMS allocated interrupt stack in bytes.
+This value must be at least as large as MINIMUM_STACK_SIZE.
+
+@item extra_mpci_receive_server_stack
+is the extra stack space allocated for the RTEMS MPCI receive server task
+in bytes.  The MPCI receive server may invoke nearly all directives and
+may require extra stack space on some targets.
+
+@item stack_allocate_hook
+is the address of the optional user provided routine which allocates
+memory for task stacks.  If this hook is not NULL, then a stack_free_hook
+must be provided as well.
+
+@item stack_free_hook
+is the address of the optional user provided routine which frees
+memory for task stacks.  If this hook is not NULL, then a stack_allocate_hook
+must be provided as well.
