Will try that. It does seem strange that the new version isn't backwardly
compatible with older source.

Though I haven't downloaded the previous version of NASM, I followed your
instructions anyway. Unfortunately, none of the 3 parts will compile. There
seems to be a problem with freeldr\freeldr\makefile and manual attempts at
command line to build the freeldr bit (under DJGPP) throw up a screen full
of errors. Attempting to make install with mingw32 does a similar thing. Do
you want me to see if I can get it to work hack the makefiles (and paths in
the source if necessary)?

If you like I can report back if and when I get freeldr to build.

Just one other thing - can freeldr boot from a second primary partition?
It's just that my WinXP bootsector is quite important! :-)

Thanks for your help.

Nick.
