Hi Quixote :-)

The cybppc.device is part of the boot rom of the cyberstorm cards (MKIII and PPC -on the MKI and MKII it was called cybscsi.device)

The best place for a CDRom type drive is the end of the scsi chain, with all harddrives before it, as all "empty" removable units will not be configured at boot time by the cybppc.device but if connected after harddrives can be "late mounted" without problems.

So, it would be wise to connect your harddrive (with it's scsi terminaison on) at the beginning of the scsi cable (connector 1), the cyberstorm scsi connector on the 68-->50 pins adaptator on the connector 2, and then the CDRom unit at the end of the chain (with terminaison on too) on connector 3. (assuming your cyberstorm is inside an A4000 Desktop supercomputer :-)

You read right, the two unit MUST BE terminated, as Phase 5 hadn't installed any terminator on the cyberstorm MKIII and PPC and an scsi chain MUST BE terminated at BOTH ENDs for proper functionning.

That's why you have to connect the haddrive (terminated) first, next the scsi controller, last any removable units (CDRom, CDR and CDRW, ZIP, JAZ, SyQuests etc...) again with the last unit fully terminated.

You must pay attention too at the 68-->50 pins adaptator you use as it MUST BE terminated on the 8 lasts lines (not used by 50 pins drives) to have a well balanced scsi chain, at least on the CyberStorms.

2/ you said your CDRom is unit 3 so you can use these mountlist with (I'm using it on my Cyb everyday, no problems ;-) :

Note : as the CDRom is the last on the 50 pins scsi chain you would like to set it to unit 6.

Hope this will help you :-)
