Re: Help Si570
- For those inclined, this method is of real high accuracy and is based on the calculation of difference of the angular speed of WWV signal and the angular speed of our VFO signal (via DSP s/w).

screen saying HP Invented. If I unplug the SB and restart, I get that
plus F9 and F10 options and then the usual startup if I do nothing.

Someone else mentioned that but I do not know what it means. For what
it's worth, the word "legacy" does not appear in the bios.
