Changes to XTIDE Universal BIOS:

• Removed INT 13h format and diagnostics functions.
• Removed INT 18h callback handler.
• Removed configuration for early/late initialization. Now XT builds always use late and AT build early initialization.
• Reduced number of supported IDE controllers from 5 to 4.
• Removed reserved configuration bytes.
• Removed simple and system boot loaders.
