This field identifies the particular device. The
LSI53C825A device ID is 0x0003. This value is the same

Register: 0x04
Command
Read/Write
The
register provides coarse control over a device’s ability to
generate and respond to PCI cycles. When a zero is written to this
register, the LSI53C825A is logically disconnected from the PCI bus for
all accesses except configuration accesses.
In the LSI53C825A, bits 3 through 5 and bit 7 and 9 are not
implemented. Bits 10 through 15 are reserved.
