Table 2. RPL Memory Enable, ISA Mode Switch Position 4 0 RPL Memory Disabled (not using the RPL feature) 1 Enabled Interrupt Level, also called Interrupt Request Level IRQ (this establishes the priority by which the adapter can interrupt the computer, the lowest value is given the highest priority). Table 3. Interrupt Level (IRQ), ISA Mode Switch Positions 5 6 0 0 Interrupt Level 9 1 0 10 0 1 11 1 1 15 Important The IBM Wireless LAN adapter does not support interrupt level sharing. Therefore, make sure that no other adapter in your computer uses the same interrupt level. If necessary, change the interrupt level of the IBM Wireless LAN adapter. If you want to use interrupt level 9 for the IBM Wireless LAN adapter, make sure that no other adapter in your computer uses interrupt level 2. Direct Memory Access (DMA) arbitration level (this establishes the priority by which the adapter can access the computer memory, the lowest value is given the highest priority. The recommended value is 3). 240 IBM PC 300/700, IntelliStation Series HMM
