I have used these cards with RedHat and Debian with both 2.0 and 2.2 kernels and they work fine. One thing to look out for is that they are ISA cards with some plug and play functions. The plug and play functionality is useless. Get the 3c5x9cfg program from the dos intsallation disks that come with the card. Boot your PC and go into BIOS setup. Next go int the Plug and Play settings and reserve an innterupt for non plug and play cards. Boot to DOS and then run the 3c5x9cfg program. There should be an option to manualy setup the card, turn of plug and play and then set it to the interupt that you reserved in the bios setup. It should work fine then so long as you have the correct module to load or compile the drivers into the kernel.
