OBP disables all LAN cards and PCI cards installed (onboard serial ports are excluded) on a system board by changing this environment variable. Internal SCSI boards on PRIMEPOWER900/1500/2500 also can be disabled.
# eeprom no-io-sb-cX=Y
# eeprom no-io-sb="XY"
# eeprom no-io-sb="XY-N"
where X is the cabinet number and Y is the slot number within the cabinet and N is logical number in the system board. The syntax is the same as Kernel memory allocation option.
This feature is intended to avoid complicated I/O operation for a system board detach, e.g. stopping application programs running with outgoing I/O devices.
