1XTIDE Universal BIOS v1.1.5 (28 November 2010)
2  * Errors are now being checked when calling previous INT 13h handler on AH=08h Read Disk Drive Parameters.
3    This fixes infinite drive checking loop on unofficial MS-DOS 7.10 installer.
4  * Better INT 40h handler detection to fix floppy drive detection with AMI 286/386 BIOS.
5  * AA55h signature no longer required when booting from floppy drives. This should make booter games work.

8XTIDE Universal BIOS v1.1.4 (24 August 2010)
9  * Correct number of drives is now returned from AH=08h when it is redirected to foreign BIOS.
10  * Interrupt controllers are now unmasked during drive reset.
11  * OS hooks are now enabled for all builds. IRQ waiting no longer uses HLT instruction to fix some EMM386 and VCPI issues.
12  * XT+ build is no more since it would now be the same as AT build

15XTIDE Universal BIOS v1.1.3 (1 August 2010)
16  * v1.1.1 broke booting from foreign drives, it is now fixed.
17  * Improved error handling a bit.
18  * Longer DRQ and IRQ timeouts to minimize write timouts with some (bad) CF cards.
19  * Default boot menu drive should now be properly selected.

27XTIDE Universal BIOS v1.1.1 (19 July 2010)
28*Booting is now possible from hard disks if floppy controller reset fails
29 since AH=00h, Disk Controller Reset now returns error code for the
30 requested drive only.
31*Now assembles with Yasm.

42 is now possible to install DOS to any hard disk from any floppy drive
43*INT 13h,AH=15h return value in DL now longer gets corrupted by drive swapping
44*Rewritten drive detection and lots of code cleaning
45*Longer timeout when detecting first drive
