6 / 66 page  AN84REV1 6 CS8920 Technical Reference Manual 1.0 Introduction to CS8920 Technical Reference Manual This Manual provides the information which will be helpful in designing a board using the CS8920, programming the associated EEPROM, and installing and running the CS8920 device drivers. It is expected that the user of this Technical Reference Manual will have a general knowledge of hardware design, Ethernet, the ISA bus, and networking software. Recommended sources of background information are: a) ISA System Architecture by Shanley and Anderson, Mindshare Press, 1992, ISBN 1-881609-05-7 b) Ethernet, Building a Communication Infrastructure, by Hegering and Lapple, Addison-Wesley, 1993, ISBN 0-201- 62405-2 c) Netware Training Guide: Networking Technologies, by Debra Niedenmiller- Chaffis, New Riders Publishing, ISBN 1-56205-363-9 As shown in the Figure 1.1, the CS8920 requires a minimum number of external components. The EEPROM stores configuration information such as interrupt number, DMA channel, I-O base address, memory base address, and IEEE Individual Address. The EEPROM can be eliminated on a PC motherboard if that information in stored in the system CMOS. Note also that the Boot PROM is only needed for diskless workstations that boot DOS at system power up, over the network. Also, the LEDs are optional.
