The DVD drive recognized by a HW info tools says:
Drive Model "HP CDDVDW TS-L633M"
Drive Revision "0301"
I'm thinking more about the SATA controller, since you can't turn the compatibility mode on the BIOS. Possible that's why it don't recognize the DVD.
Since this is a laptop, was the DVD driver not delivered with the laptop ? Setting the BIOS to compability or mode or not will not matter. What I meant in my previous postings is that when you get this error message no DANIS506.add is even loaded or OS/2 is not even active what so ever. From what I'm reading I get the impression you think OS/2 is active.
This OS2CSM stuff was done by Veit Kannegeiser and its a kind of mini OS that reads the kernel etc from the diskette images on CD. This is unpacked to RAM disk in memory. But when this error message occurs nothing of OS/2 is loaded.
Saijin_Naib I did see you mention the DANIS506.ADD driver. Its none related in this case since OS/2 is not loaded.
That the CD Martin also worked inside a Virtual Machine is not a warranty it works the same as booted on real hardware. Since under an OS loaded and then a VM accesing the CD it will do this in a different fashion then when booting via the BIOS.
