Problem with the nios2-linux-20100621

Thx a lot. I've 'wget' some older nios2-linux from niosftp and will try them later. Another question is that, for older versions , I can select DM9000 as well as DM9000A with offloading checksum , and some instruction said that for DE2 dev kit, I should select the later one. I've tried it but there is no string like 'dm9000 driver xxxxx' in nios2-terminal and 'ifconfig' cannot bring the eth0 uplink. But when I choose DM9000, some errors occurs. Have you encountered such problems? Thanks!!!! :D
