If you can test this, +please let me know! Also note that you will have to change these +settings if your soundcard is set for a non-standard address or IRQ. +Please check your documentation (or verify with any provided DOS utilities +that may have come with your card) and set the IRQ or address fields +accordingly. + + +Also: You can configure more then one card on a single DMA using +the conflicts keyword in your configuration file. This is useful for boards +with more then one type of emulation. + + +Probing problems: Since the SB16 uses the same IRQ and addresses for +the different drivers, some of the snd drivers will not be probed because +the kernel thinks there is a conflict. This can be worked-around by +using the "conflicts" keyword on the sb16's device line. + + +For further information, contact multimedia@freebsd.org + + - Jordan Hubbard (jkh@freefall.cdrom.com) + - Steven Wallace (swallace@freefall.cdrom.com) + - Sujal Patel (smpatel@wam.umd.edu) |
