 INT 2Fh, Function 1510h - Why??

Why would anyone use this function, it SENDS DEVICE REQUEST but doesn't
return anything? Can anyone explain??

According to my documentation, this appears to be an extension to
int 2fh/0802h - EXECUTE DEVICE DRIVER REQUEST. The extension function
concerns CD-ROM. You put the drive number in CX (0 = A, 1 = B, etc.) and
the address of the device driver request header in ES:BX. The call will
update that header.

This is from the interrupt list that accompanies "Undocumented DOS".
The registers have the contents as above, and a reference to int 2fh/
0802h is given for further details.
