I have a LiteOn LTR-24103S CD drive in a 486, but the drive occasionally crashes. For example, it froze down when I ejected CD. The computer crashed as well, but after reset it started normally except the drive was not found. Powering it down solved the problem, so I suspect that drive's firmware had crashed.

Currently it has firmware XB03, and it appears that there are newer versions. However, this site I found doesn't have the firmware itself, just a link that doesn't work anymore. Any idea where to find firmwares for old LiteOn drives?
