15.2 Device Configuration Tables
One device configuration table, containing extended device information,
corresponds to each device in the system. The TEST command dispatcher
and the system test monitor use this data structure to fetch the appropriate
diagnostic code to execute from the ROM or load into RAM to be executed.
There are two types of device configuration tables:
One listing information about devices that are part of the kernel (see
Section 15.2.1)
One listing information about the TURBOchannel options that may be
present in one of the six option slots (see Section 15.2.2).
15.2.1 Kernel-Resident Device Configuration Table
Figure 22 shows the format of the kernel-resident device configuration table;
