There are NO silkscreened component IDs on the PCB. NONE whatsoever. OC-2729 Boot PROM Kit for RPL
Further OC-2335 Chip Stuff Alfred Arnold said: Turns out that the Olicom uses the really cheesy National DP83800 controller chip. Has an ISA style interface, no DMA, just plain PIO data transfer. Tx and Rx buffers are integrated, but 3K Tx buffer and 5K Rx buffer is a joke for a 100Mbit card...now I know why our hardware guys here opted for the SMSC and added 128K buffer space to it (and that was just an ISDN access router). Given that Olicom didn't add any 'magic glue' between the NIC and the Microchannel bus, the data sheet should be sufficient for writing a driver and we don't need Olicom's help. Though the sheet was not available on National's site any more, our hardware guys still had a copy of the PDF file. This PDF file has a footer that says 'National Semiconductor Confidental - Do Not Copy'...whatever that means for us... AdapterID 6447 Olicom Ethernet MCA 10/100 Adapter I/O Address Location
