Table J-15: Simple Recovery from BTS Router rommon Boot
Step Action
CAUTION
The file sequence on the CF memory card can not be verified with application programs which place
the listed file names in alphabetical order (for example, certain Unix telnet applications, Unix
directory listing commands, and Windows file managers such as Windows Explorer). This portion of
the procedure is intended for use only with applications, such as HyperTerminal, which do not list
directory contents alphabetically.
7 After a successful reboot with IOS, perform the following to correct the cause of the boot to rommon:
7a – Enter the dir slot0: command to display the CF memory card directory, and, if the IOS file is
not the first file listed, perform the procedure in Table J-10, steps 25 through 32, or Table J-12, as
applicable, to correct the situation.
7b – If the IOS file is the first file, enter the following command to display the contents of the
startup–config file:
show startup–config
A response which begins similar to the following will be displayed:
BTSRTR1#sh start
Using 1589 out of 57336 bytes

no logging console
!

mode y–cable
standalone
!
7c – If the file listing contains a “boot system” line, examine it for the correct IOS filename.
7d – If the boot system slot0: filename is incorrect, enter the following, using care to type the filename
correctly:
boot system slot0:IOS_filename
Where IOS_filename = the filename of the IOS noted in step 2, above.
7e – Replace the boot system line in the startup–config file with the line entered in step 7d, above, by
entering the following:
copy runing–config startup–config
