If MSD does not find a PC entry in the BOOTCONF.SYS file, it normally responds with a boot
image file name based on the MBA type code for the ROM in the PC. This default image name
has the format MSD$<type>.SYS. For example, the default image file name for a PC with an
NIC which has a MBA type code of 003 would be MSD$003.SYS. This allows you to create
boot image files based on the NIC type, without adding an entry in the BOOTCONF.SYS file.
If you do not want MSD to respond with these default image filenames, use the
“NODEFAULT” command line option. In NODEFAULT Mode MSD responds to the PC with an
error message instead of an image filename. This is a security feature and prevents any PC
that is not defined in BOOTCONF.SYS from booting.

There are several messages related to MSD operation that may appear at an MBA-equipped
PC.
MSD: no reply: (only in verbose mode)
The MBA ROM in the PC has broadcast a message in an attempt to communicate with
MSD, but no reply was received. This message occurs only in cases where MSD is not
installed on at least one server on the network, or if the server in which the MSD NLM
is loaded is not currently operating.
This message may also occur within the first few minutes of the MSD NLM being
loaded at a file server, as it takes several minutes for all file servers on the network to
be aware of the NLM's existence.
After this message is issued, MBA defaults to its normal operation, and attempts to
contact any available file server for its boot image.
MSD: [msdname] Found server <servername>:
This message appears at the PC during normal operation, and indicates the name of
the MSD NLM that serviced the request, and the name of the file server from which the
boot image file is retrieved.
MSD: [msdname] Server <servername> is unavailable:
This message appears at the PC if MSD is unable to locate the file server that was
specified in the BOOTCONF.SYS entry defined for the PC.
