Last change on this file since 119 was 118, checked in by Tomi Tilli, 14 years ago

Changes to Configurator v2:

  • Warm boot flag is now reset when rebooting.
  • Checksum generation no longer corrupts images when image size is less than EEPROM size.
  • Configuration and flashing menu items are now displayed when loading BIOS from EEPROM.
