* Added UART module from ao486 project (COM1 assigned to USER I/O pins) * Automatic loading of the BIOS ROM from /games/PCXT directory * BIOS ROM hot swapping from the OSD menu * Updated the code to the latest version of the SDRAM module of KFPC-XT, but not yet implemented in the core... needs to be revised and improved, it does not work properly.
