- And Adaptec's non-bus mastering card (1422B, I think) costs about $100
- less. That's probably the cost of licensing the bus-mastering
- chipset. Radius also has to pay this.
-
- As for using two bus-master cards at once, it's not a problem as long
- as they both agree on a protocol. That's why two Adaptec boards can
- co-exist on one computer. If the Radius board uses the same protocol
- that Adaptec does (likely, if they use the same chipset - does anyone
- know if they do?), then it can co-exist easilly.
