Full Version: Serial and Parallel PCI Ports requiring a legacy I/O Address in DOS
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Issue:
Legacy hardware and software may require that a Serial, or Parallel port, be located at its traditional I/O Address (i.e. 0x3f8, 0x2f8, 0x3e8 & 0x2e8 for Serial Ports and 0x378 & 0x278 for Parallel Ports).

This is because the hardware, or software, assumed these ports would always be located at fixed addresses and never move. However, with the evolution of add-in PCI cards these ports are now mapped by the BIOS at boot time and by default aren’t set to the I/O Address expected by the legacy hardware, or software.

Resolution:
Lava does have two DOS based utilities for manually changing a card’s I/O Address and IRQ mapping to work within the standard legacy I/O Addresses.

These utilities can be found on the software utilities page (http://lavalink.com/support-drivers/lava...utilities/) under the “LAVA SETADDR.EXE and SETIRQ.EXE” link.

Note: Due to certain BIOS limitations, these utilities do not work with 100% of systems.
