You don't need to mount it. In fact, that would interfere. Open the file MD5SUM in a text editor that does not wrap long lines. The filename for each individual checksum is at the end of each line. Find the filename corresponding to the CD ROM you want to check and edit the filename out, replacing it with the correct device for your CD ROM device. Delete the rest of the file, and save the result to a new filename. Example: The first line of MD5SUM is: 3051115a70ebc491d438dd21632b1412 FC3-i386-disc1.iso So, you can start by deleting everything below this line. Then, replace FC3-i386-disc1.iso with the device disignation for your CD ROM. One possible result might be: 3051115a70ebc491d438dd21632b1412 /dev/cdrom Of course, you must supply a correct device designation.i Next, save to a new file name, perhaps MD5cdr1 Now, you can run md5sum like this: md5sum -c MD5cdr1 You really only need to do the first CD ROM for now. Once you are successfully booting the installation, we can go back and do the rest. > Under windows, I cant check a folder and it's subfolders > with WinMD5Sum. Whatever. This is a nonsequitor.
