Advantech PCA-6275 manual IRQ-xx assigned to PCI/ISA PnP, DMA-x assigned to PCI/ISA PnP

3.7.1 IRQ-xx assigned to : PCI/ISA PnP

These fields indicate whether or not the displayed IRQ for each field is being used by a legacy (non-PnP) card. Two options are available: PCI/ISA PnP or Legacy ISA. The first option, the default setting, indicates that the displayed IRQ is not used to determine if an ISA card is using that IRQ. If you install a legacy ISA card that requires a unique IRQ, you must set the field for that IRQ to "Legacy ISA". Say for example that you install a legacy ISA card that requires IRQ 10. You must then set "IRQ-10 assigned to :" as "Legacy ISA".

3.7.2 DMA-x assigned to : PCI/ISA PnP

These fields indicate whether or not the displayed DMA channel for each field is being used by a legacy (non-PnP) card. Two options are available: PCI/ISA PnP or Legacy ISA. The first option, the default setting, indicates that the displayed DMA channel is not used to determine if an ISA card is using that channel. If you install a legacy ISA card that requires a unique DMA channel, you must set the field for that channel to "Legacy ISA".

3.7.3 Used MEM base addr : N/A

This field allows you to set the base address and block size of a legacy ISA card that uses any memory segment within the C800H and DFFFH address range. If you have such a card, select a used base address from the six available options. The "Used MEM base addr" field will then appear for selecting the block size. If you have more than one legacy ISA card in your system that needs to use this address range, you can increase the block size to either 8 K, 16 K, 36 K or

64 K.
