Hi,

I've read somewhere that you can use syscons to map IO memory into
'userland'? Is this possible?

I have a simple ISA card that maps in at 0x240 - 0x24F - which I'd like to
read and write to without going through creating a kernel device driver
etc...

A device driver will probably follow - but if I can just get to the card I
can use a heap of existing code I've allready got to drive it - and worry
about the driver when I have more time...


Any info greatly appreciated,

Regards,

Karl Pielorz
