This is a call for testers for the if_al driver for the ADMtek AL981 "Comet" 10/100 ethernet chip. This chip is fairly new, so I don't know how many people actually have boards with them, but if you have one please give the driver a try. I have only tested 10Mbps at this point since I can't test anything else at home. The driver is at: http://www.freebsd.org/~wpaul/ADMtek/3.0 To add it, do the following: - Download if_al.c and if_alreg.h and copy them to /sys/pci - Edit /sys/conf/files and add a line that says: pci/if_al.c optional al device-driver - Edit your kernel config (e.g. /sys/i386/conf/GENERIC) and add a line that says: device al0 - Compile a new kernel and boot it. This driver should work on FreeBSD 3.0 and up, though I have not tested it with the new bus stuff (it still uses the old PCI interface mechanism). FreeBSD/i386 and FreeBSD/alpha are both supported. (I do plan to make a 2.2.x version soon, as well as convert the other drivers to the new bus architecture. Just at the moment I have too many other things to do.) The AL981 is yet another tulip style clone. Unlike the real tulip, the AL981's receive filter is programmed using registers; there's one perfect filter entry for the station address and a 64-bit multicast hash table. The AL981 has a built-in 10/100Mbps transceiver with pseudo-MII interface. It also supports power management and wake on lan. Very nice programming documentation is available from http://www.admtek.com.tw. The AL981 has one downside, which is that like all the other taiwanese chips, it doesn't decode all of the bits in the RX DMA buffer address, which means that receive buffers must be longword aligned. This makes life a little difficult on the alpha, but at least this limitation is properly documented in the manual. A big thanks to ADMtek for sending me two test boards and for making their documentation freely available. As usual, if you have problems, please let me know at wpaul@skynet.ctr.columbia.edu. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
