Chapter 4: Address Selection
When using DOS, the PAD128 address can be selected anywhere within an I/O address
range 100-3FF hex, providing that the addresses do not overlap with other functions. If
in doubt, refer to the table below for a list of standard address assignments or use the
base address locator program FINDBASE provided on CD or diskette. It will assist you
to avoid an address conflict.
Windows 95, 98, and NT will select an appropriate base address for you. Windows will
most likely put the card at one of the following addresses: 240, 100, 140, 180, 1C0, 2C0,
or 300. If you are using one of these operating systems, you can skip this chapter.
