Changes:

• XTIDECFG: Fixed a bug from r459 where the menu option for selection of default boot drive would be missing if the BIOS had been built without MODULE_HOTKEYS. The menu option is now visible if either or both of MODULE_HOTKEYS and MODULE_BOOT_MENU is available.
• BIOS: Disabled ATA-ID validation by adding a new define (NO_ATAID_VALIDATION) and making it the default for all builds since at least two WD Caviar drive models are incompatible with it.
• Fixed the "No Fixed Disk Present in FDISK"-bug introduced in r551 which means the Tiny build now works without including MODULE_DRIVEXLATE.
• Fixed a bug from r528 where pressing hotkey F6 would not initiate detection of serial drives.
• Fixed a bug from r186 in DisplayFormatCompressed.asm where the boot menu would print the IRQ in hexadecimal format when it should be in decimal format.
• Optimizations and fixes.
