1  * Errors are now being checked when calling previous INT 13h handler on AH=08h Read Disk Drive Parameters.
2    This fixes infinite drive checking loop on unofficial MS-DOS 7.10 installer.
3  * Better INT 40h handler detection to fix floppy drive detection with AMI 286 BIOS.

5XTIDE Universal BIOS v1.1.4 (24 August 2010)
6  * Correct number of drives is now returned from AH=08h when it is redirected to foreign BIOS.
7  * Interrupt controllers are now unmasked during drive reset.
8  * OS hooks are now enabled for all builds. IRQ waiting no longer uses HLT instruction to fix some EMM386 and VCPI issues.
9  * XT+ build is no more since it would now be the same as AT build

12XTIDE Universal BIOS v1.1.3 (1 August 2010)
13  * v1.1.1 broke booting from foreign drives, it is now fixed.
14  * Improved error handling a bit.
15  * Longer DRQ and IRQ timeouts to minimize write timouts with some (bad) CF cards.
16  * Default boot menu drive should now be properly selected.

19XTIDE Universal BIOS v1.1.2 (26 July 2010, no public release)
20  * Fixed a bug where Disk Parameter Table was accessed with wrong pointer register after writing last block.
21  * Cleaned AH=00h, Disk Controller Reset a bit.

24XTIDE Universal BIOS v1.1.1 (19 July 2010)
25*Booting is now possible from hard disks if floppy controller reset fails
26 since AH=00h, Disk Controller Reset now returns error code for the
27 requested drive only.
28*Now assembles with Yasm.

31XTIDE Universal BIOS v1.1.0 (first stable release, 2 May 2010)
32*Lite and full operating modes
33*Diagnostic cylinder no longer has to be reserved
34*Slave drives again work without master present
35*32-bit transfers for VLB and PCI IDE controllers
36*16- and 32-bit transfers are enabled on all builds
37*Boot menu hotkeys for all drives
38*Drive swapping is handled separately for floppy and hard disk drives so it
39 is now possible to install DOS to any hard disk from any floppy drive
40*INT 13h,AH=15h return value in DL now longer gets corrupted by drive swapping
41*Rewritten drive detection and lots of code cleaning
42*Longer timeout when detecting first drive
43*Minimum number of floppy drives can be specified if autodetection fails
44*Maybe other changes that i have forgotten

46XTIDE Universal BIOS v1.1.0 configuration and flashing program (idecfg.com)

64*Strings and boot menu are displayed properly on BIOSes that corrupts
65 AH when returning from INT 10h/AH=Eh
66*L-CHS addressing is now used for <=504MiB drives even if LBA is supported
