AdapterId 05C1Ch AdapterName "DCA IRMAtrac Token-Ring Adapter/Convertible" NumBytes 5 NamedItem Prompt "Adapter Data Rate" choice " 04 Mbits / Second " pos[0] = 0xxxxx1xb choice " 16 Mbits / Second " pos[0] = 0xxxxx0xb Help "Choose 4 Mbps or 16 Mbps. Default: 4 Mbps. The data rate you choose must match the data rate of your token-ring network, or your adapter will fail to insert into the ring. If your RIM operates at a fixed speed (the speed is not software-selectable), this parameter is ignored." NamedItem Prompt "DMA Transfer Type" choice " Bus-Master DMA " pos[0] = 011xxxxxb choice " PIO " pos[0] = 001xxxxxb Help "Choose Bus-Master DMA or Programmed I/O (PIO). Default: Bus-Master DMA." NamedItem Prompt "Interrupt Level (IRQ)" Choice " IRQ 03 " pos[1] = xxxxxx01b int 3 Choice " IRQ 10 " pos[1] = xxxxxx10b int 10 Choice " IRQ 11 " pos[1] = xxxxxx11b int 11 Choice " IRQ 02 " pos[1] = xxxxxx00b int 2 Help "Choose one of the following interrupt level values: 2, 10, 11, or 3 (from highest to lowest priority). Default: 3. The interrupt level enables the adapter to request resources from the PC's CPU and determines the priority the CPU uses to answer requests. Make sure that the IRMAtrac adapter does not have the same interrupt level as another adapter. (The Set configuration program does not indicate interrupt conflicts. You need to manually check for conflicts.) If an interrupt conflict occurs while the IRMAtrac adapter is operating, a variety of malfunctions can result." NamedItem Prompt "DMA Arbitration Level" Choice " 4 " pos[2] = 00xxxx10b arb 4 Choice " 5 " pos[2] = 01xxxx10b arb 5 Choice " 6 " pos[2] = 10xxxx10b arb 6 Choice " 7 " pos[2] = 11xxxx10b arb 7 Help "Choose a DMA arbitration level in the range of 4 to 7, with 4 having the highest priority and 7 having the lowest priority. Default: 4. If two devices want to use the DMA channel at the same time, the highest priority device wins. Each adapter in your system must have a unique arbitration level. An asterisk (*) next to your arbitration selection means there is a conflict. If there is a conflict, you must choose a new arbitration level. If you choose automatic configuration, the Set configuration program searches for an arbitration level that is not in use, starting with arbitration level 4 through 7. In most cases, you will not notice the effect of the arbitration level on IRMAtrac's performance." NamedItem Prompt "Adapter I/O Address Range" Choice " Primary Adapter " pos[3] = xxxxxxx0b io 0A20h-0A3Fh Choice " Secondary Adapter " pos[3] = xxxxxxx1b io 1A20h-1A3Fh Help "Choose Primary Adapter (0A20-0A3F) or Secondary Adapter (1A20-1A3F). Default: Primary Adapter. The I/O address range should not conflict with another adapter's address. If an asterisk (*) appears next to your selection, the address range conflicts with another adapter. You can change either IRMAtrac's address range or the address of the other adapter that has the same address. If you choose automatic configuration, the Set configuration program chooses an address that does not conflict with another device in your system."
