Here's an example, which I wrote for the MicroVAX. Took me a bit to
find this.<br>
<br>
The program creates a file called ROM.EXE and copies the boot ROM
into that file.<br>
Note the " vbn=#<^X20040000/512>" line
- that says that the ROM is mapped into physical address 20040000 on
that system. Likely different for others. Size of the ROM is
calculated by the "page_count" variable.<br>
