       NAME
             crom - EISA NVRAM Driver

       DESCRIPTION
             The crom driver is used to access information stored in EISA
             nonvolatile RAM.  The following type of information is
             accessed/displayed:

                   Information on each board installed in the system.

                   Version of the Compaq EISA Configuration Utility (ECU)
                   used to configure the system.

                   Log and display critical and correctable errors in the
                   error logs.

             The crom driver accesses EISA slots and function records using
             the following interfaces:

             eisa_read_slot(int slot, char *buffer)
                   Read slot data from eisa cmos memory.

             eisa_read_func(int slot, int func, char *buffer)
                   Read function data from eisa cmos memory.

          ioctl Calls
             The crom driver supports two ioctls:

             EISA_CMOS_QUERY
                   Fills the data buffer from eisa cmos memory then
                   searches for the specified key.

             ROM_CALL
                   Provides a mechanism to make an INT 15 BIOS call from
                   user space via eisa_rom_call().  The eisa_rom_call()
                   requires as an argument, a pointer to the regs structure
                   (defined in <proc/regset.h>):

          FILES
             <proc/regset.h>
