Hello,
on my 4000/60 I have a dka300 500MB disk internal
the scsi host adapter is ID 6

I Attached an external SCSI CDROM which is a Yamaha CDRW 

the station does not see it

with show dev I can only see the net interface, the internal disc and the
scsi host adapter  ICannot see the cdrom

on a 4000/90 instead this cdrom was seen.

also on other 4000/60 station I Cannot see this cdrom external device.

Could it be because the internal disk terminates the SCSI chain ??

how can I check if this is the reason ??

what can I do if  IWant to do a network install ??
I tryed with installin gmop on a machine with netbsd ndistribution but I
WAs unsiccessfull.

thanks

Rick
