A legacy device is a non-PnP device. You need to tell your BIOS about them because it can't detect what IRQs/DMA channels they are using, and you don't want it to configure your PnP devices to conflict. > a.

Or does the DMA 0/1 ID not matter? It probably doesn't matter, but try both. But I suspect the sound cabling & DMA channels are just for voice modes like SVD and aren't really affecting your ability to talk to the modem at all. > c.

It appears in all four possible configurations so it may be worth enabling. You mentioned that it doesn't appear in /proc/interrupts; what about /proc/ioports? hamish -- Hamish Moffatt, [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] Latest Debian packages at ftp://ftp.rising.com.au/pub/hamish.
