So far, Reset-on-Eject is never turned on for the first HDD based XBE the BIOS loads, regardless of it's media flags - that's one of the tricks of the UDE (see
here).
If they're still using this to program 5713 Kernel XBOXs, it'd be another
HDD based, non-dashboard, XBE - like Update.xbe - that would run on 5713 Kernel (See
here).
