Lavalink's inctructions for their cards are quite clear but may be out of date. I recently moved a dual parallel PCI card to a RedHat 7.3 machine and am unclear how I should modify modules.conf to pick up the new ports. /sbin/lspci -v shows (among other things): 00:10.0 Parallel controller: Lava Computer mfg Inc Lava Dual Parallel port A (prog-if 01 [BiDir]) Flags: slow devsel, IRQ 14 I/O ports at ecd8 [size=8] 00:10.1 Parallel controller: Lava Computer mfg Inc Lava Dual Parallel port B (prog-if 01 [BiDir]) Flags: slow devsel, IRQ 14 I/O ports at ecd0 [size=8] Their instruction say to then look in "conf.modules" which I interpreted as "modules.conf" for parport entries. Here is my modules.conf: alias scsi_hostadapter aic7xxx alias eth0 3c59x alias parport_lowlevel parport_pc pre-install pcmcia_core /etc/rc.d/init.d/pcmcia start alias usb-controller usb-uhci alias sound-slot-0 cs4232 post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || : pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || : options sound dmabuf=1 alias synth0 opl3 options opl3 io=0x388 options cs4232 isapnp=1 Note that there is no options line for the current parallel port. I know what to add for the additional Lava ports but what do I specify for the current port? I would presume the address to be 0x378 but what IRQ? Am I artificially constraining my system if I specify an IRQ? Should I do something like: alias parport_lowlevel parport_pc options parport_pc io=0x378,0xecd8,0xedc0 irq=auto,auto,auto Note that the address and IRQ specifications for the Lava card are as they recommend. -- Eric McRae, Electro-Logic Machines, Inc. 511 Root St., Port Townsend WA, 98368 Phone/Fax: 360.379.0969, http://www.elmi.com -- To unsubscribe, send mail to: linux-parport-request <at> torque.net -- -- with the single word "unsubscribe" in the body of the message. --
