Release Notes for DOS Config Utility for the PCI Classic Board This DOS utility (for use with the ClassicBoard PCI adapter only) will allow you to see where the BIOS assigned the cards resources, change the I/O mapping, and change the IRQ mapping. This utility is for DOS only, and will not work in a DOS Window. This utility does not check to see if the resources are already in use. If the changes to the cards resources cause any conflicts, power-cycle the machine and try a different value. entering the command DIGICFG -v will show the assigned resources of the card. entering the command DIGICFG -h will display the command options If you do: DIGICFG -b100 -i7 -e The card should be remapped to ports starting at 100h IRQ7 with the interrupts on the card enabled. The StatusPort address will be 140h, or 240h, etc. depending on the starting IO port address. If you do: DIGICFG -v It should show the card has been remapped. Note: To consistently assign the same settings to the adapter, the appropriate command line with parameters should be placed in the auoexec.bat file. Known limitations: The address block must start on a 256-byte boundary defined by the PCI 2.1 specification. The addresses are in a block, no way to break the block. The design is locked by the design of the parts used. The addressing logic uses 80h locations as a result. So the board would do ports 100h, 108h, ... 138h, with the StatusPort at 140h. A four port would take the same address block, with the StatusPort at 140h. The PLX part used and the UARTs used are the reason for this addressing.
