+.Sh NAME
+.Nm drivers.conf
+.Nd "driver configuration file for boot floppies"
+.Sh DESCRIPTION
+The file
+.Nm
+is used during the release build process.
+A
+.Fx
+release includes two installation floppies.
+The first floppy image,
+.Pa kern.flp ,
+contains a statically linked kernel.
+The second floppy image,
+.Pa mfsroot.flp ,
+contains
+.Xr sysinstall 8 ,
+a collection of essential commands necessary for installation, and
+kernel modules to supplement the boot kernel.
+Once the system has booted,
+the modules present in the
+.Pa /stand/modules
+directory of the MFSROOT floppy will automatically be loaded by
+.Xr sysinstall 8 .
+.Pp
+The
+.Pa /usr/src/release/${arch}/drivers.conf
+file contains a list of drivers that should be omitted from the boot
+kernel and installed as kernel modules on the MFSROOT floppy.
+Each driver is described on a separate line; fields on each line are
+separated by tabs or spaces.
+.Pp
+The first field,
+.Ar driver ,
+is the name of the driver in the kernel configuration file.
+This is used by
+.Pa driver-remove.pl
+to remove drivers from the boot floppy kernel configuration
+file that are included as modules on the MFSROOT floppy.
+.Pp
+The second field,
+.Ar filename ,
+is the name of the associated kernel module (without the 
+.Pa .ko
+extension).
+.Pp
+The third field,
+.Ar floppy ,
+specifies which floppy disk should include the kernel module.
+Currently, only a value of 2 is valid here (representing
+.Pa mfsroot.flp ) .
+In the future, a third
+.Dq "driver floppy"
+may be added.
+.Pp
+The fourth field,
+.Ar type ,
+specifies the driver category.
+This field is currently unused.
+.Pp
+The fifth field,
+.Ar description ,
+provides a short description of the device driver.
