Last change on this file since 372 was 371, checked in by gregli@…, 13 years ago

Small changes. 1) Changes biosdrvs.com to output CR+LF instead of LF+CR, consistent with DOS/Windows, but I did not update the Assembly Library as this would break the Configurator; 2) Put a C/C++ section in Version.inc for the serial server; 3) Configurator defaults the EEPROM address after scanning for a EEPROM in memory (as it does for loading the BIOS from ROM); 4) Added a command to the Configurator main menu to save chages to the file from which it was loaded (if it was loaded form a file), which is symmetric with the Load command and more discoverable than exiting DOS and then being prompted (which is still there too, if changes are unsaved).
