How can I get the serial number of a CD ROM disc? I need it to make a library of name,title,... of audio tracks on a cd.<br>It seems there are some serious programmers in this forum, I hope there is one who knows someting about registers becouse I know DOS interrupt 21h needs to be called with register AL=69h and AH=00h (to get serial) or AH=01h (to set serial). I only need to get the serial number but I don't know how or where the numbers are returned.<br>Note: I work in Turbo Pascal and assembler language can be implemented but please be clear in any answer(s) because I don't know anything of assembler, I just use it <p>Bert Vingerhoets<br><a href=mailto:vingerhoetsbert@hotmail.com>vingerhoetsbert@hotmail.com</a><br><a href= > </a><br>
