I'm afraid I only know how to verify a CD on Linux, and even there I have to scratch my head and try to remember it because I don't do it that often.
A simple way to get the sum for a CD is: md5sum </dev/cdrom (where /dev/cdrom might be /dev/hdc, or however you refer to your CD rom drive) The problem with the simple method is that sometimes cd burners add a few sectors of zeros to the end of the CD. The method above adds those sectors to the md5sum, so it might not match even if the CD is good. Another approach uses dd to copy exactly the right number of bytes from the CD before sending them to md5sum. For that you need to know the size of the .iso file, and give dd the proper arguments so it will read only that many bytes. There might be a much simpler approach, depending on how far your system boots with the CD. Did it make it to the menu? I think there is a "check CD" option on the menu, but I could be mistaken.
