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?
did you configure the xt-ide bios before writing it to eeprom ?

How can I configure It? There are 6720 lines of code
from https://www.xtideuniversalbios.org/
All BIOS binaries available here must be properly configured with the configuration tool XTIDECFG.COM before flashing/programming to ROM. In addition to configuring the BIOS file for use with your specific hardware you must also make sure the file is checksummed by saving the file to disk as that will create the padding and checksum required for installation in a computer.
Always use the version of XTIDECFG.COM supplied together with the BIOS files.
If you haven't read the documentation available here then you are strongly encouraged to do

Maybe useful for testing still. Please remember it's outdated by now. 😔
Newer versions use different LBA algorithm, afaik, so DOS partitions must be re-created after an XUB upgrade.
