I have been trying to make an Amstrad pc 1640, I updated the BIOS to XT-IDE Universal BIOS v2.0.0.3 and tried to boot but it shows the error message "Error; suma de comprobación incorrecta ROM externa; Dirección de ROM = D8000"
translated "Error; bad external rom checksum; ROM address = D8000", I also tried with the other address (C8000)
Any ideas?
