SubjectBogus dma value for parport in FIC SD11
From

The DMA autodetection for Via 686A seems to be broken; it is returning a bogus
'255' DMA value. It is configured in the BIOS as ECP, IRQ 7, DMA 3.

0x378: FIFO is 16 bytes
0x378: writeIntrThreshold is 8
0x378: readIntrThreshold is 8
0x378: PWord is 8 bits
0x378: Interrupts are ISA-Pulses
0x378: possible IRQ conflict!
0x378: ECP port cfgA=0x10 cfgB=0x00
0x378: ECP settings irq=<none or set by other means> dma=<none or set by other means>
parport0: PC-style at 0x378 (0x778), irq 7, dma 255 [PCSPP,TRISTATE,COMPAT,ECP,DMA]
parport0: dma 255 in use, resorting to PIO operation
parport0: cpp_daisy: aa5500ff87(b8)
parport0: assign_addrs: aa5500ff87(b8)
parport0: cpp_daisy: aa5500ff87(b8)
parport0: assign_addrs: aa5500ff87(b8)
parport_pc: Via 686A parallel port: io=0x378, irq=7, dma=255
lp0: using parport0 (interrupt-driven).
