Is this something I should be worried about ? I intend to connect a ZIP drive to
the port tomorrow.
I have no parport= commands on my kernel command line.
My system is a dual PPro-200 SMP system and the parallel port on the motherboard
is set up in the bios as
ECP, io=0x378, irq=7, dma=3
Chipset details are
> Bus 0, device 7, function 0:
> ISA bridge: Intel 82371SB PIIX3 ISA (rev 1).
> Medium devsel. Fast back-to-back capable. Master Capable. No bursts.
> Bus 0, device 0, function 0:
> Host bridge: Intel 82441FX Natoma (rev 2).
> Medium devsel. Fast back-to-back capable. Master Capable. Latency=32.
