Your BIOS tells you the DMA channel your parallel port is configured to run with. Something like, device ppc0 at isa? port? tty irq 7 drq 3 should be ok if DMA channel is 3 in your BIOS ECP setting. It might be channel 1 though, then set drq to '1'. > >----------------------------+----------------------------------------------- >Chuck Robey | Interests include any kind of voice or data >chu...@glue.umd.edu | communications topic, C programming, and Unix. >213 Lakeside Drive Apt T-1 | >Greenbelt, MD 20770 | I run picnic (FreeBSD-current) >(301) 220-2114 | and jaunt (Solaris7). >----------------------------+----------------------------------------------- > > > > > >To Unsubscribe: send mail to majord...@freebsd.org >with "unsubscribe freebsd-current" in the body of the message > -- nso...@teaser.fr / nso...@freebsd.org FreeBSD - Turning PCs into workstations - http://www.FreeBSD.org To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
