Well, they'll have to do until I can find some time to go out and snag some new ones then... Or until I can make my way over to pricewatch, I suppose. At any rate, I'll keep it in mind; thanks. > A long time ago the driver tried to offer 100baseTx link beat for a few > seconds when started. > But this jams most 10baseT repeaters.. a very bad thing.

In other news, I seem to have shoehorned the current 3c59x driver into compiling directly into the kernel. It actually wasn't that hard (the Makefile changes were trivial); basically all I had to do was remove some of the "#ifdef MODULE" and a couple of references to "linux/modversions.h", which doesn't exist when your kernel isn't using modules. Oh, and calls to "module_init" and "module_exit" towards the end. If anyone's interested, I've put up the patches at: http://apocalyptech.com/linux/3c59x/ Thanks again for your help, CJ -- WOW: Kakistocracy | "The ships hung in the sky in much the same apocalyptech.com/wow | way that bricks don't." - Douglas Adams, [email protected] | _The Hitchhiker's Guide To The Galaxy_ _______________________________________________ vortex mailing list [email protected] http://www.scyld.com/mailman/listinfo/vortex
