These drivers are left over from Aironet pre-Cisco acquisition so theres not much documentation. I dont see DOS support for the 350s but the 340s are still out there. In any case, edit the .ini or .ahc (ad hoc file is only used if no access point is being used, just peer-to-peer) files with your text editor to set the options you desire. Then put those and the .com packet driver on your boot disk, load the .com with a device statement in the cofig.sys and it should initialize the card. If you are using a PCMCIA card, make sure you load a DOS compatible card services BUS driver first.
