source: xtideuniversalbios/trunk/Assembly_Library/Src/Menu/Dialog/DialogString.asm@ 580

Last change on this file since 580 was 568, checked in by krille_n_@…, 10 years ago

Changes:

  • SerDrive: Using named pipe mode (serdrive -p) now works under Windows XP/2000/Server 2003.
  • checksum.pl: Added a compatibility fix for 3Com 3C503 cards.
  • XTIDECFG will now scan every possible segment address to find and load the BIOS and/or its settings from EEPROM. This should simplify things for people using combined option ROMs.
  • Fixed a bug from r521 in BootSector.asm where the BIOS would not display a timeout error if it failed to load the boot sector from harddrive.
  • Fixed a bug from r541 in CompatibleDPT.asm where CompatibleDPT_CreateDeviceParameterTableExtensionToESBXfromDPTinDSSI would generate an invalid checksum in the DPTE.
  • Optimizations and other fixes.
