* can support an optional "combo" implementation. If the PSP sees the

* tables. Using this, support for multiple product generations may be
* built into one image. If the PSP$ cookie is found, the table is a
* normal directory table.
*
* Modern generations supporting the combo directories require the
* pointer to be at offset 0x14 of the Embedded Firmware Structure,

* Creates the OSI Fletcher checksum. See 8473-1, Appendix C, section C.3.
* The checksum field of the passed PDU does not need to be reset to zero.
*
* The "Fletcher Checksum" was proposed in a paper by John G. Fletcher of
* Lawrence Livermore Labs. The Fletcher Checksum was proposed as an
* alternative to cyclical redundancy checks because it provides error-
* detection properties similar to cyclical redundancy checks but at the
* cost of a simple summation technique. Its characteristics were first
* published in IEEE Transactions on Communications in January 1982. One
* version has been adopted by ISO for use in the class-4 transport layer
* of the network protocol.
*
* This program expects:
* stdin: The input file to compute a checksum for. The input file
* not be longer than 256 bytes.
* stdout: Copied from the input file with the Fletcher's Checksum
* inserted 8 bytes after the beginning of the file.
* stderr: Used to print out error messages.
