PCI Configuration

DMA x Used By ISA [No/ICU]

These fields indicate whether or not the displayed DMA channel for each
field is being used by a legacy (non-PnP) ISA card. The default setting indi-
cates either that the displayed DMA channel is not used or an ICU is being
used to determine if an ISA card is using that channel. If you install a legacy
ISA card that requires a unique DMA channel, and you are not using an
ICU, you must set the field for that channel to [Yes]. Configuration options:
[No/ICU] [Yes]
