Chipset

The system is built around the HP Astro chipset:

HP Astro chipset

Astro memory and I/O controller connects to the two processors via the Runway processor bus (2.0 GB/s), the memory bus (2.0 GB/s) and eight I/O channels (ropes — aggregate 2.0 GB/s) and contains both memory, I/O and cache controllers

Four Elroy PCI bridges connect the PCI slots and I/O devices on the onboard PCI bus to the Astro with an aggregate bandwidth of 2.0 GB/s on seven I/O channels (one of the eight channels of the Astro controller is unused)

PCI 64/66 I/O slot on two channels — 0.5 GB/s

PCI 64/66 I/O slot on two channels — 0.5 GB/s

PCI 64/66 I/O slot on two channels — 0.5 GB/s

Onboard I/O devices (Fast Ethernet, SCSI, audio, IDE/USB etc.) on one channel — 250 MB/s

National 87560 (Super I/O), integrates USB, RS232, parallel, floppy and IDE

National 87415 IDE controller
