RH channels: LOGICAL ACTUAL TYPE MISCELLANEOUS 5 CHN1 EI 0 CHN0 SI MASK=0x03 1 CHN2 SI MASK=0x03 7 CHN3 CI PORT#=0x3 http://i.imgur.com/ZmLpwhV.jpg So you have a CDDI (fddi over copper) interface and 3 SCSI ports. http://i.imgur.com/KYl73d8.jpg BOOT40.EXE tell me about hung SCSI devices (Shocker, none plugged in). BTSCFC Can't find any channels Can't tell if I'm missing a drive the rest of the OS would be on. I think that "boot40" tells it to boot from chan4/drive0. The DFxxx are KL10 cpu diagnostics, BIN are code for the chanel-cpu's In you directory there is no operating system, it can still be on the the disk in the OS file-system, but you need to teach the boot to look at that drive.. Do you have more than 1 drive? -P
