appear in /dev. Interface hardware ioctls (not protocol or routing) can
be performed on the descriptor. The SIOCGIFCONF ioctl may be performed
on the special /dev/network node.
This driver supports PCI Xr-based and ISA Xem Digiboard cards.
dgm will go away soon if there are no problems reported. For now,
configuring dgm into your kernel warns that you should be using
digi. This driver is probably close to supporting Xi, Xe and Xeve
cards, but I wouldn't expect them to work properly (hardware
donations welcome).
The digi_* pseudo-drivers are not drivers themselves but contain
the BIOS and FEP/OS binaries for various digiboard cards and are
auto-loaded and auto-unloaded by the digi driver at initialisation
time. They *may* be configured into the kernel, but waste a lot
of space if they are. They're intended to be left as modules.
The digictl program is (mainly) used to re-initialise cards that
have external port modules attached such as the PC/Xem.
Incredibally useful for debugging kernels using vmware.
Vmware com1 is diverted to one side, and gdb listens to the other side.
viola.. instant debugging sandbox on one system.

o Notice also that it's listed as "aud" not "audit" which will
probably change in the near future with updates to the auditing
implementation.
implying that they aren't used for the rest of the system.
Fix the lies:
253 is used by mfs (bad MFS for not registering it).
254 is a magic cookie inside of the dev code in at least one place.
255 is -1 which is magic in a different way in the dev code.
So, that means that 200-252 are reserved for local users. A grep for
252 didn't turn anything up, so I'm assuming it and lower are safe.
And I thought I was being smart by allocating our local major numbers
from 254 on down. This caused very very odd problems that were hard
to track down: close not being called, sync failing at reboot, etc.
only two conflicts, cdev #98 and cdev #99. These should be fixed.
MAKEDEV should probably be merged as well.
Static majors are (hopefully) going away one day soon.
