ATAPI CD-ROM word reads no longer incorrectly discard the upper 16 bits, fixes the CD-ROM problems; Significantly rewrote parts of the AHA-154x and BusLogic emulation, NT 3.1 RTM and MS-DOS drivers now works correctly; The function in cdrom.c to read data blocks from the disc now correctly advances the position of the sector to read in non-passthrough mode, fixes multiblock reads from directly mounted ISO's; Both ATAPI and SCSI now always check for Unit Attention and Not Ready on command execution.
