FIGURE 4 PMC BISERIAL-II PS2 INTERNAL ADDRESS MAP
The address map provided is for the local decoding performed within the PMC
BiSerial-II. The addresses are all offsets from a base address, which is assigned
by the system when the PCI bus is configured.
The VendorId = 0x10EE. The CardId = 0x001D. Current revision = 0x00
