This is a set of utilities that allows the user to capture the contents of the rom sets in either the PC or the AT. It allows the content of the rom to be written to a file called xtrom for the XT or atrom for the AT. A utility called romsplit is provided for the AT that allows the atrom file to be split into two files that represent the even and odd bytes and which are called tempeven and tempodd, respectively. Note that this is not necessary for the XT. Another utility called lsplit is provided to allow the large files produced by romsav to be split into files that will fit into the desired destination eproms. For prom burners that accept data format in the Motorola S record format, a utility called binex is provided that converts a binary file into standard S record format. A typical session is described below for an AT.
1. Run the command "romsavat". This will produce a file called "atrom".
2. Run the command "romsplit" (copy "atrom" to a new file temp). This will produce two files called "tempeven" and "tempodd".
3. If the destination eproms are 27256 then it is not necessary to split the files into smaller ones, otherwise run the command "lsplit tempeven", where is the decimal size of the destination file in bytes (e.g. "lsplit 16384 tempeven" to make tempeven into two files called "F0" and "F1" that will fit into 27128 eproms. Rename the files to some new name so that they will not be overwritten at the next step. Now run the command "lsplit tempodd" to produce files for the odd byte eproms.
4. If you are producing S records run "binex " on each file that you wish to convert to S record format.
5. Feed them to a prom burner and keep track of which eproms were even and odd and the order in which they were burned to allow you to install them properly in the target system.
