	A good starting point is to set the dip switch ~~2 and 8 ON. This will put Serial port on IRQ 4. and base address 0x3F8 (COM1)~~.		A good starting point is to set the dip switch settings in the image.

	Note: Only one of SW1.1 - SW1.4 should be ON. All switches can be off if software doesn't use interrupt based I/O.		Note: Only one of SW1.1 - SW1.4 should be ON. All switches can be off if software doesn't use interrupt based I/O.

	For the ROM Address you can switch all of SW3 ON except 5. This will put the floppy controller ROM at address 0xC8000. If you have an XTIDE make sure its at a higher address than this.		For the ROM Address you can switch all of SW3 ON except 5. This will put the floppy controller ROM at address 0xC8000. If you have an XTIDE make sure its at a higher address than this.

			Once the settings are finalized and everything is working as expected put the EEPROM into read-only mode by switching off 2.2. This will prevent spurious bus signals from overwriting your EEPROM.

	Based on my testing address conflicts will ~~most~~ likely erase the EEPROM so before plugging it in make sure there are no conflicts. If your EEPROM got erased then download the firmware bin file and use a programmer to re-program.		After your system boots you will be prompted "Press F2 to run the Multi-Floppy BIOS configuration utility... this will get you into configuring the floppy on the controller card. Define your floppy drives there. Then on reboot it will print

			Found BIOS extension ROM at C8000 or whatever address you selected, initializing...

			Multi-Floppy BIOS Version 2.2. Copyright (C) 2010 ...
			FDC 1 at 03F0, IRQ6, DRQ2
			Drive 0: ...

			If you don't see these messages, or don't have option to press F2 then there is conflict in the BIOS extension ROM address you may want to define it at another address location.

			If you are confident there are no shorts on the floppy controller you may want to try this controller card on another machine to isolate the problem.

			Based on my testing address conflicts will likely erase the EEPROM so before plugging it in make sure there are no conflicts. If your EEPROM got erased then download the firmware bin file and use a programmer to re-program.
