It should work in 2.4 providing you use the loading options for ncr53c400a and set a port and no IRQ (read mine did).

The 53c400a can be programming to an address by software - either by magic sequences or I believe according to pin strapping by ISAPnP. Its been a long time since I touched such junk however and if you want to do anything useful with your computer while scanning (like waving the mouse point around) get something else!
