Appendix C. Making a Router Load File from Multiple Disks

If a software load arrives on multiple disks, use the procedure in the following sections to combine the loads into one load file that the router can use at the time of booting.

The first disk contains the following four files that you need if you want to fragment an existing load for transport on multiple diskettes.

cutup.c

(UNIX C source file that can be compiled using a standard C compiler)

cutup.exe

(DOS)

Use the following files for reassembling the load fragments onto a DOS or UNIX server.

kopy.bat

(DOS)

kopy

(UNIX shell script)

Assembling a Load File Under DOS

To assemble a load from the two diskettes, use the DOS batch file provided on diskette 1 (KOPY.BAT) using the following syntax:

kopy <installation_drive><destination_directory>

Before assembling the load make sure that you have created a destination directory, and that you have inserted the first diskette in the drive specified by the installation_diskette_drive parameter. The following example illustrates this procedure.

B:\>kopy b: c:\source\cutup\tmp
B:\>copy c:\gw0/B c:\source\cutup\tmp\gw.tmp
1 file(s) copied
.
Please mount the second diskette
Press any key to continue . . .

B:\GW1
1 file(s) copied
B:\>rename c:\source\cutup\tmp\gw.tmp  gw.ldc

B:>

Assembling a Load File Under UNIX

To assemble a load from two UNIX diskettes, you can use the UNIX Bourne shell script (kopy) provided on diskette 1 using the following syntax:

kopy<installation_drive><diskette_directory><destination_directory

Before assembling the load make sure that you have created the mount and destination directories, and that you have inserted the first diskette in the drive specified by the installation_diskette_drive parameter. The following example illustrates this procedure.

kopy /dev/fd0 /kew /pcfs
 
Please insert the first diskette
 
Copying the first load file fragment
 
Please mount the second diskette
 
Copying the second load file fragment
 
Load file reassembly was successful
 
# ls /kew
 
gw0   gw1   gw.ldc

If you can't use the UNIX Bourne shell script, you can assemble the load manually using the following procedure:

1. Copy the load fragments on the two diskettes (gw0 and gw1) into a directory on the UNIX file system.

2. Type the following UNIX command:

   cat gw0 gw1 > gw.ldc
   

   The resulting file (gw.ldc) is the assembled router load.

Disassembling a Load File Under DOS

To disassemble a load under DOS, use the CUTUP.EXE file as follows:

cutup<file_extension><file_name><cut_length>

The file_extension is attached to the front of each slice needed to cut. The file_name is the DOS file name of the file to be disassembled. The cut_length is the length that CUTUP.EXE makes each fragment as it disassembles the file. The following example illustrates this procedure.

   C: \source\cutup>dir
   Volume in drive C has no label
   Volume Serial Number is XXXXXXXX
   Directory of C: \SOURCE\CUTUP
   .0730934:46p
   ..0730934:46p

Disassembling a Load File Under UNIX

To disassemble a load under use cutup.c. Begin by compiling the program using your UNIX compiler to make a cutup executable file. Then use the following syntax:

cutup<file_extension><file_name><cut_length>

The file_extension is attached to the front of each slice needed to cut. The file_name is the DOS file name of the file to be disassembled. The cut_length is the length CUTUP.EXE that is used to disassemble the file. The following example illustrates this procedure.

#  ls -la
