EtherDisk Diskette for the EtherLink Plus Adapter
System Resources
The EtherLink Plus adapter uses three system resources:
- I/O address range
- Interrupt level
- DMA channel
The adapter's options are factory set with the following settings:
- I/O base address 300h
- Interrupt level 3
- DMA channel 1
Before you install the adapter, make sure that these settings do not conflict
with similar settings on other peripherals.
Listed below are commonly used peripherals and the adapter option settings
they might conflict with. If any of these peripherals are installed in your
computer, check which resources they are using and make sure the EtherLink Plus
adapter options are not set to use the same resources. Other peripherals,
not mentioned in these lists, might also cause conflicts.
