What exactly do you mean by this? The PnP BIOS obviously
resides in the ROM which is read-only and so you *cannot*
have your data sturctures in the same segment as the entry
point.

But if you mean that you need to read the PnP header
structure, you can use nearptrs. (__djgpp_nearptr_enable).
It's in the FAQ.

Don't think so. But you're mixing up segments and selectors. The
name "selector" is when you're refering to prot. mode and "segment"
when you're using real mode.
