Re: Updated menu.c32

[Steven L. Seed]

That's unfortunately not going to work for us. I'm using the 4.0 pre 
release because of it's support for larger ISO boot images. I was 
looking at the code and saw a mention of the real_mode_seg starting at 
4000h. Peter Vreman mentioned in his post this...

"When I change the real mode segments to 5000h-6000h-7000h then I can 
also use the localboot."

I'd like to know if that means I need to modify the code and if so, what 
variables need to be set. Unfortunately, in the 4.0 code for syslinux, 
the value of real_mode_seg is assigned by the linker. I have no idea how 
to modify that. I'm wondering if I need to be asking this question on 
another list like boot-land.net.
