Whats the story on PCI?
PCI is a platform independent hardware standard; for details visit the PCI Special Interest Group at http://www.pcisig.com. The intention is that future machines will be developed with PCI interfaces only. However this doesn’t mean that SBus is going away – there is still a massive installed base which will be supported for many years to come. The first PCI frame buffer from Sun is the PGX. This is an 8 bit device with features and performance comparable to the TGX. It supports a wide range of resolutions, and is configured using a program called m64config rather than the old prom-value method required by the TGX. Also unlike previous frame buffers it does not use sense codes to determine the resolution. For full details of PCI cards that are supported in the Ultra 30 series, including graphics and other products, see http://www.sun.com/pci.
