If so, then given the designation, Is it possible that it is a Yamaha Musical Products original that they just second sourced to opti? My PAS has one of these on it, too. If it is, then there is a book about soundcards that i almost bought at Barnes and Noble ( and i cant remember the name ) that has the asm API to a butload of theser guys, so pleading at the unenthusiastic tech support may not be needed... > > So - at this point I'd like to ask the group: > > 1) Does anyone have OPTi's phone number, so I can call them > directly. > > 2) Are other sound cards that have this phenomena, if so, > what to people do about the printer wanting to use IRQ 7. > Uh - oh! The soundcard interrupt aggravation rears it's ugly head! You're in for a bitch. It should be solvable. My crusty old Micronics 386 has a jumper setting for choosing the printer IRQ to either 7 or 5. The annoying part of this is that I wanted to keep my sio ports stock with the generic kernel, since that is my primary way of getting my upgrades into the system ( i only have one freebsd machine ). Int 5 is assigned to sio3 i believe... I sort of have it all sorted out on my machine , but it really just takes a lot of annoying fiddling to get it all to fly. And u wind up with a much less generic kernel... hope this helps.. > - Thanks - > - Dave Rivers - > > ******************************************************************************* John Utz spaz@stein.u.washington.edu idiocy is the impulse function in the convolution of life
