RSPC and RS/6000 Platform Architecture (RPA) systems may support attachment of devices using the following buses:
Provided the device support software is installed, PCI and SCSI devices are configured automatically whenever the Configuration Manager program (cfgmgr) is run at system boot and when no conflict (for example, the same SCSI ID for two SCSI devices) is found.
Non-native ISA devices will have to be configured manually, and you may even need to change some of the device's predefined or customized attribute values especially when configuring two or more ISA devices of the same type.
Even though you can have multiple adapters on one system, you may not always be able to run different devices on the same adapter. There are various different configurations according to the specification of your particular machine. For example, if you have a SCSI Single-Ended (SE) Ultra Controller, only SE SCSI devices can connect to it, not differential devices. Likewise, If you have a 100 Mbps Ethernet LAN, a 10 Mbps Ethernet card will not work.
Device information is contained in a predefined database or a customized database that makes up the Device Configuration Database managed by the Object Data Manager (ODM).
The device information stored in the Device Configuration Database allows the automatic configuration of microchannel devices on RISC System/6000 systems and PCI devices on RSPC and RPA (non Micro Channel) systems whenever the Configuration Manager (cfgmgr) program is run at system boot and run time.
As for non-native ISA devices, the information data contained in the predefined part of the configuration database is not sufficient to perform automatic, conflict-free, ISA device configuration. Thus, the user needs to manually customize some values to be used by the ISA device (for example, interrupt level, shared memory address, and so forth) when configuring the device for the first time.
