Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes
the processor to ignore the console Break key. Clearing bit 8 causes the
processor to interpret the Break key as a command to force the system into
the bootstrap monitor, thereby halting normal operation. A break can be sent
in the first 60 seconds while the system reboots, regardless of the configura-
tion settings.
Bit 10 controls the host portion of the IP broadcast address. Setting bit 10
causes the processor to use all zeros; clearing bit 10 (the factory default)
causes the processor to use all ones. Bit 10 interacts with bit 14, which controls
the network and subnet portions of the broadcast address. (See table 4-6.)

Bits 11 and 12 in the configuration register determine the baud rate of the
console terminal.
Table 4-7 shows the bit settings for the four available baud rates. (The default
baud rate is 9600.)

Bit 13 determines the server response to a bootload failure. Setting bit 13
causes the server to load operating software from ROM after five unsuccessful
attempts to load a boot file from the network. Clearing bit 13 causes the server
to continue attempting to load a boot file from the network indefinitely. The
default setting for bit 13 is 1.
