others that that the mountlist is the standard os 3.9 file...
Assuming that you have access to the other files of OS 3.9, too, just copy "AmigaOS ROM Update" to Devs: and "SetPatch" to C: and reboot. After that scsi.device should see the CD-ROM drive.
Or use the computer you use to read the CD to create an emergecny disk.
