Source listing in bootstrap.s is incorrect.
The OSI C1P alternative boot file format works, but the code in the source listing does not match the ASCII-coded hex translation (which is actually used). This is confusing to anyone trying to maintain the code. Also, the source code did not assemble when ASM is defined. Also removed use of branch macros and an unnecessary "<" operator. With these changes the source file should correctly match what is used at run time.
