The site for the saxon lyre has your tuning information:

" Hucbald's De Harmonica Institutione (ca. 880) contains discussion and an illustration of lyre tablature for the common 6-string lyre along with tuning information. Hucbald is explaining the work of Boethius, and gives his audience an example of how Boethius' musical system would describe their lyres. Thus Hucbald's examples are descriptive rather than prescriptive of the tuning found in his day. He notes that intervals between the strings of the lyre are tone-tone-semitone-tone-tone (Hucbald, 22-23). In modern notation, that tuning maps to C-D-E-F-G-a, or D-E-F#-G-a-b, these being the first six notes of a major scale or, looked at another way, the last three and first three notes of a major scale, or the last note followed by the first five notes of a Dorian scale.
