 If the hash is incorrect, the kernel will inform you about this in "dmesg"
 upon module initialization, and tell you of the correct hash.
 
-You can determine the hash of the product ID strings by running
-"pcmcia-modalias %n.%m" [%n being replaced with the socket number and %m being
-replaced with the device function] from pcmciautils. It generates a string
+You can determine the hash of the product ID strings by catting the file
+"modalias" in the sysfs directory of the PCMCIA device. It generates a string
 in the following form:
 pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFEE84pc0877B627pd00000000
 
 The hex value after "pa" is the hash of product ID string 1, after "pb" for
 string 2 and so on.
 
-Alternatively, you can use this small tool to determine the crc32 hash.
-simply pass the string you want to evaluate as argument to this program,
-e.g.
-$ ./crc32hash "Dual Speed"
