In a DOS netstation, a 3C503 EtherLinkII board configured for INT 3,
I/O 300, DMA 5 will return the error message:

   MAC0004 Syntax Error in PROTOCOL.INI - Invalid Parameter Value

The error is caused by the use of DMA 5 on the 3C503 board.  The only
DMA values allowed for the 503 board are DMA 1 or 3, including any other
8-bit or 16-bit boards seated in an 8-bit slot on the DOS netstation.  The
higher interrupts are only for 16-bit boards in a 16-bit slot.
