Does anybody have a code fragment to read the boot sector of a PC running Linux (Red Hat 6.2 if it matters)?
Linux by itself does not use a boot sector. It can be loaded by various boot loaders like LILO, grub or loadlin. While the latter one is a Dos executable, the former two contain their own boot sectors. You may want to look into their source code (C, of course) to find out more.
I think my terminology may be faulty. What I am after is the Master Boot Record (MBR) which I think will be present on a PC, almost irrespective of the operating system. I have downloaded the source for grub but there is a lot to plough through. I just hoped somebody had done it before.
Yep, on a Linux system, usually lilo or grub is stored in the MBR (though they can also be stored elsewhere).

I do not know whether this will be of any help, but on FreeBSD-Systems you will find a command # boot0cfg -f file ad0 which will print the content of the MBR on disk ad0 into file . Perhaps you will find something similar for Linux? Have a look at # man boot !?
