1XTIDE Universal BIOS v1.1.4 (24 August 2010)
2  * Correct number of drives is now returned from AH=08h when it is redirected to foreign BIOS.
3  * Interrupt controllers are now unmasked during drive reset.
4  * OS hooks are now enabled for all builds. IRQ waiting no longer uses HLT instruction to fix some EMM386 and VCPI issues.
5  * XT+ build is no more since it would now be the same as AT build
8XTIDE Universal BIOS v1.1.3 (1 August 2010)
9  * v1.1.1 broke booting from foreign drives, it is now fixed.
10  * Improved error handling a bit.
11  * Longer DRQ and IRQ timeouts to minimize write timouts with some (bad) CF cards.
12  * Default boot menu drive should now be properly selected.
15XTIDE Universal BIOS v1.1.2 (26 July 2010, no public release)
16  * Fixed a bug where Disk Parameter Table was accessed with wrong pointer register after writing last block.
17  * Cleaned AH=00h, Disk Controller Reset a bit.
20XTIDE Universal BIOS v1.1.1 (19 July 2010)
21*Booting is now possible from hard disks if floppy controller reset fails
22 since AH=00h, Disk Controller Reset now returns error code for the
23 requested drive only.
24*Now assembles with Yasm.
27XTIDE Universal BIOS v1.1.0 (first stable release, 2 May 2010)
28*Lite and full operating modes
29*Diagnostic cylinder no longer has to be reserved
30*Slave drives again work without master present
31*32-bit transfers for VLB and PCI IDE controllers
32*16- and 32-bit transfers are enabled on all builds
33*Boot menu hotkeys for all drives
34*Drive swapping is handled separately for floppy and hard disk drives so it
35 is now possible to install DOS to any hard disk from any floppy drive
36*INT 13h,AH=15h return value in DL now longer gets corrupted by drive swapping
37*Rewritten drive detection and lots of code cleaning
38*Longer timeout when detecting first drive
39*Minimum number of floppy drives can be specified if autodetection fails
40*Maybe other changes that i have forgotten
42XTIDE Universal BIOS v1.1.0 configuration and flashing program (
43*Now works as a generic EEPROM flasher
44*Improvements to configuration menus
45*SDP can be completely disabled
48XTIDE Universal BIOS v1.0.0_RC2
49*No more boot menu slowdown when no XTIDE Universal BIOS
50 controlled drives present
51*Hard disks are now reset properly.
52 This fixes some Block Mode related bugs.
53*Major improvements for error handling
54*Small improvements for interrupt handling
57XTIDE Universal BIOS v1.0.0_RC1
58*Fixed 386+ stack exception bug
59*Stack is relocated for boot menu even if DPTs are not stored to 30:0h
60*Strings and boot menu are displayed properly on BIOSes that corrupts
61 AH when returning from INT 10h/AH=Eh
62*L-CHS addressing is now used for <=504MiB drives even if LBA is supported
65XTIDE Universal BIOS v1.0.0_b4
66*Boot menu with drive swapping
67*Block mode transfers
68*Cylinder limiting
69*Drive detection read errors are now properly detected
70*A little longer timeout value when detecting drives
71*Minor optimizations to save some bytes
74XTIDE Universal BIOS beta3
75*BIOS configuration and flashing program finally available
76*No more conflicts with other hard disk BIOSes
77*Slave drives should now be detected without master
78*Timeouts now use system timer
79*Variables can now be located to top of base memory
80*Completely rewritten interrupt handling
81*Minor optimizations to 8-bit transfers
82*CTRL can be held down to skip initialization
83*Late initialization to fix compatibility issues with old systems
86XTIDE Universal BIOS beta2
87*AT build and support for 16-bit IDE Controllers
88*XT+ build for 188/186/V20/V30/286 XTs
89*Auto detection for timeout values (AT+)
90*Minor optimizations
93XTIDE Universal BIOS beta1
94*Initial release
