Hi!
I have a tuner card in my computer, which is connected via an ISA-16
bus. The card is controlled through inportb() and outportb() calls when
I use MSD-DOS, BUT, how do I access these functions in FreeBSD ..?
I succeded to get it work in Linux through ioperm(), and two assembler
macros. I hope that FreeBSD isn't too much harder..?
Extra info: card is a Tuner + Teletext chip + Audio control, wich is
controlled through a I2C(philips one)-bus. The I2C bus is controlled
through the ISA-16 bus, using one port.
Please email answers -> peterb@ludd.luth.se
Thanks on forehand :)
