Welcome to the forum
I had the same problem with my 3540A and an MSI mobo (848P).
I don't remember if I totally fixed it and could actually boot from the CD, but I remember that to use the drive in native mode (without DOS or Windows), I had to manually enable "ide busmaster" in the BIOS. This busmaster is needed to run optical devices in native mode. Looks like MSI doesn't consider that this setting should be enabled by default... :rolleyes:
Give it a try, who knows. Good luck
