I guess I'll throw my two cents in. I've been using an abit bp6 with two celeron 366s and using to Netgear FA310TX rev c1 I belive. I never had a probs with using two tulip cards with smp enabled. I find these cards to work great. I don't think I ever had any troubles with them. Thanks to all those who help maintain and improve the tulip drivers. Arie
