INFO: Writing ROMable Code with Microsoft Languages

• Microsoft LINK for MS-DOS, versions 1.x, 2.x, 3.x, 4.x, 5.01.20, 5.01.21, 5.1, 5.13, 5.15, 5.3, 5.31.009, 5.5, 5.60.339

The Microsoft LINK utility provided with Microsoft language compilers, is not designed to create absolutely addressed or "ROMable" code.

To write ROMable code, code which can be loaded at an absolute address at run time, using Microsoft language products, you'll need to acquire a special linker. Third party linkers are available for this purpose which can be obtained by calling any of the following companies:

The following magazine articles are a good source of information for the implementation details of a LOCATE utility. A LOCATE utility is used to create a binary or ROM image from an EXE produced by a DOS linker. These articles each contain source code for an implementation of a LOCATE utility in addition to the description of the function of a LOCATE utility.
