• Bits 11 and 12 of the software configuration register determine the data
transmission rate of the console terminal. Table 4-8 shows the bit settings for
the four available data transmission rates.
• Bit 13 of the software configuration register determines the system response
to a bootload failure.
–
Setting bit 13 causes the system to load Cisco IOS software from flash
memory after five unsuccessful attempts to load a boot file from the
network TFTP server.
–
Clearing bit 13 causes the system to continue attempting to load a boot
file from the network TFTP server indefinitely (default).
