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: 15 16 http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c 17 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 (mdc (a] etherboot.org) and the Etherboot-Discuss list 46 (etherboot-discuss (a] lists.sourceforge.net) 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". 49 50 Regards, 51 52 Marty Connor 53 mdc (a] etherboot.org 54 http://www.etherboot.org/ 55
