Can you use an ATA33 CDR on a motherboard with IDE connection for ATA 66-100-133 if the motherboard is a Foxconn 648fx4mr-es?

In theory, yes. ATA 133 is backwards compatible all the way to ATA 33. However, if you have trouble, the most likely problem is that the motherboard bios needs an update.

I had this problem on an ASUS MB. The CD drive would appear in the startup/BIOS and I could even boot to the CD-ROM drive to begin to install windows, but once the install got 2/3 done and windows loaded all its drivers, the CD drive would disappear as far as the operating system was concerned. If you are having a similar problem, go to the MB manufacturer's website and update your bios.

WARNING - this can be very risky, since it is possible to kill a Motherboard by installing the wrong BIOS on it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
