The main() function of startup main.c looks like this:
... paddr_t mdrvr_addr; ... /* * Collect information on all free RAM in the system. */ init_raminfo(); /* In a virtual system we need to initialize the page tables */ if(shdr->flags1 & STARTUP_HDR_FLAGS1_VIRTUAL) { init_mmu(); } /* The following routines have hardware or system dependencies that may need to be changed. */ init_intrinfo(); /* Allocate a 64 KB data area. */ mdrvr_addr = alloc_ram(~0L, 65535, 1); /* Register the minidriver and its handler function. */ mdriver_add("mini-data", 0, mini_data, mdrvr_addr, 65535); ...
The name stored in the system page for our minidriver is mini-data.
