chain.c32: update reactos= option for modern value

Changed from "seg=0:0x8000:0x8100" to "seg=0x0F80"

Reactos is "alpha", so the only version of Reactos that its devs support
is the "latest" at each time. Older versions of Reactos are not
relevant / supported by Reactos' devs.

 option to store corrected BPB values.
