[syslinux] [PATCH] mboot using module path

[Damien]

Hey,

Yes, it would help,
the pxelinux code AFAIK, uses option 210 to get the path prefix, and
this is what is used as the CurrentDirName. The mangling function uses
PathPrefix when (IMHO) it should use CurrentDirName. The patches sent earlier
changes that in the mangling function and implements chdir as a function to
change CurrentDirName through syscall 0x22 - 0025h (a strcpy...). Iow,
PathPrefix
is safe, and can be restored anytime.
I only jumped in because this 127 chars limit is blocking me. If
someone can change that without the linker complaining that's fine too
:)

Thanks for the ideas.
