Panasonic CF-M2 > PIII class CPU on 440BX chipset + Neomagic 256AV/ZX SVGA and sound > On my Thinkpad, which has the nearly identical Neo audio/video rig, I had to boot it with a bot-floppy containing a utility from IBM to check and set all device resources (DMA,IRQ, etc.) to disable the onboard modem (which I don't use anyway). The way the Thinkpad is architected for wDOS the modem and sound card were sharing an IRQ. See if you can find such a utility for your laptop and check to see if there's and heinous resource sharing that is causing your sound card to be 'hidden' behind another device. /* * John Bleichert * syborg@stny.rr.com * http://vonbek.dhs.org/latest.jpg */ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
