                      3: 
                      4: This is a tulip and clone driver for Etherboot.  See the revision
                      5: history in the tulip.c file for information on changes.  This version
                      6: of the driver incorporates changes from Bob Edwards and Paul Mackerras
                      7: who cantributed changes to support the TRENDnet TE100-PCIA NIC which
                      8: uses a genuine Intel 21143-PD chipset.  There are also various code
                      9: cleanups to make time-based activities more reliable.
                     10: 
                     11: Of course you have to have all the usual Etherboot environment
                     12: (bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
                     13: (7.16.99) or later of the tulip.c driver compiled in to support some
                     14: MX98715 based cards.  That file is available at:

                     18: NOTES
                     19: 
                     20: I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
                     21: a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
                     22: both 10 and 100 mbits. Other cards based on the tulip family may work as
                     23: well.
                     24: 
                     25: These cards are about 20$US, are supported by Linux and now Etherboot,
                     26: and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
                     27: 10/100 half/full duplex. It seems like a pretty good value compared to
                     28: some of the pricier cards, and can lower the cost of building/adapting
                     29: thin client workstations substantially while giving a considerable
                     30: performance increase.
                     31: 
                     32: On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver 
                     33: lets the card choose the fastest speed it can negotiate with the peer
                     34: device.  On other cards, it chooses 10mbit half-duplex.
                     35: 
                     36: I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
                     37: According to the data sheet the MX98715A supports up to 64K (27C512)
                     38: EPROMs, 
                     39: 
                     40: I've liberally commented the code and header files in the hope that it
                     41: will help the next person who hacks the code or needs to support some
                     42: tulip clone card, or wishes to add functionality.
                     43: 
                     44: Anyway, please test this if you can on your tulip based card, and let
                     45: me ([email protected]) and the Etherboot-Discuss list
                     46: ([email protected]) know how things go.  I also
                     47: would appreciate code review by people who program.  I'm a strong
                     48: believer in "another set of eyes".
