Can you tell me about the woman from Berhampur and the vision that brought her to Shirdi?

Certainly. Chapter 28 of the Shri Sai Satcharitra tells the wonderful story of a devout lady from Berhampur who was drawn to Shirdi by Baba. She had a vision in a dream where Baba appeared at her door and specifically asked for khichdi food. Although she had never had a direct darshan, this powerful vision left a strong impression. After her husband, a Post Department officer, was transferred to Akola, the couple became very eager for Sai's darshan and made the journey to Shirdi, marveling at the extraordinary nature of Sai's maya, as mentioned in the text.
