3.3 Subsystem and Subsystem Vendor ID

The Subsystem ID and System Vendor ID for the LSI21003 are provided in Table 3.9. The EEPROM of the LSI21003 contains the ID numbers. During system initialization, the ID numbers are loaded into the Subsystem Vendor ID and Subsystem ID registers of the imbedded SCSI controller, the LSI53C1010. For more information on the operation of the Subsystem Vendor ID and Subsystem ID registers, refer to the LSI53C1010-33 PCI to Dual Channel Ultra3 SCSI Multifunction Controller Technical Manual.
