I saw in the FAQ a tip regarding this not recogizing the cd as bootable, which suggests using a floppy based boot manager to overcome this (it suggests that the issue is with the bios). I will try that out sometime, but I am certain that the cd should be viewable from within windows. It has an autorun file, after all.
I'm not sure what you are saying here. Is the CD no longer viewable under Windows? I didn't catch that from the first post, even after rereading it. Yea, the CD should be viewable under Windows, I don't know how they could make any change that would prevent that without making the change too obvious, or come up with any good reason why they would want to. It sure doesn't seem likely thay any update would keep the CD from booting, but then again it didn't seem likely that an update would stop a NIC from working that previously worked, even after the PC is completely powered down and then cold booted into Knoppix without running any windows code. If Microsoft malware can chane the NIC EEPROM to screw with Linux, then it's not out of the question that they would change the computer's BIOS to stop it from booting Linux. I'm not ready yet to say that is what happened, but I don't trust Microsoft enough to rule it out.

Are you sure the CD drive is still functional?

Do let us know if Smart Boot Manager helps, if it does it really puts suspicion on the BIOS being changed, although I don't really expect that.
I put any of the burned knoppix cds (present and past versions) into the laptop, and either the system becomes so busy processing the cd that the desktop becomes unresponsive (applications that are already running still work, but the desktop is not refreshed, and is too busy to even respond to mouse clicks), or comes back with an error message, which I identified in the first post. Other cds work fine, even burned cds in this laptop. I am certain that the cd drive is working. It might be that there is a "security concern" that the service patch introduced.
