One approach would be to initialize a pointer to the variable using an
absolute value, e.g.

	char *bios_copyright = (char *) 0xf8000064;

But if you absolutely must define a name with external scope which the
linker will map to a given absolute address, your best bet is to create
an ASM86 module with the proper absolute origin, and defining the
variable as a FAR symbol.  Assemble with NOTYPE and link with your
program, declaring the symbol in C with the 'far' keyword.

For most purposes I would go with the first method.
