I cleaned, created a 32MB partition on the 8GB SD card.  I get a keyboard error immediately at boot with and without the sd card.  It is the same error message get if I was using an AT keyboard or did not have one plugged in at all.  I also tried changing the base ROM address to 0xD8000.  See error message I get immedately at boot before any XTMAX output is displayed.\n\n\u003cimg width=\"3000\" height=\"4000\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/ef5a8269-ee1c-4348-bf85-af6a25847d41\" /\u003e\n\nThe keyboard I am using is a hybrid XT / AT keyboard with a selector switch on the bottom.  It is a Mitsumi KPQ-E99YC keyboard.\n\nThank you for your help.\nScotty","author":{"url":"https://github.com/sw8496","@type":"Person","name":"sw8496"},"datePublished":"2026-05-03T16:16:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/52/Projects/issues/52"}
