PCI Bus
PCI bus 0 contains the onboard Ethernet, video, USB, and PCMCIA
controllers.
PCI bus 1 contains the PCI slot. From a PCI configuration standpoint,
the virtual slot number of a device plugged in the slot is 1.
The operating system supports basic configuration, interrupt control,
memory management and IO access for PCI cards plugged into this slot.
The operating system does not support bus-mastering by the PCI slot
device.
PCMCIA
New or upgraded components of application programs and the operating
system can be copied from the PCMCIA memory card to Disk-On-Chip
flash memory to replace and upgrade the existing components.
