Hey all - on my 2.1-development system (Jan2 or so kernel), I am trying to get my sound cards to work. I have both a GUS and a PAS16 in my machine. I have compiled in support in my kernel like this: device snd4 at isa? port 0x240 irq 15 drq 6 vector gusintr device snd3 at isa? port 0x388 irq 10 drq 7 vector pasintr device snd2 at isa? port 0x220 irq 5 drq 1 vector sbintr All three devices get recognized at boot time. I am not sure, however, how to differentiate between tvarious devices MAKEDEV has created for them - that is, how do I know which audio, audio or audio1 is my PAS or my GUS? Also, there is a dsp, dsp1, and a dsp16. Finally there is a midi, a mixer and a mixer1. Experimenting a bit shows that the only devices I can get to work are dsp1 and audio - everything else results in strange screechy noises from the speakers (very GUS-like screeches, when it plays back random data in its memory). In any case, any idea on how to get things working? I remember a conversation a while back about incorrect init of the GUS with these drivers - is that the situation here? Thanks all... Second question - I have found that with the following device in my kernel: device lpt0 at isa? port "IO_LPT1" tty irq7 vector lptintr I can only print in polled mode - if I switch to interrupt driven mode (lptcontrol -i) the printer takes hours to print even one small line. Polled mode, however seems to work OK. Then I noticed a conversation in which someone stated that we sould not be using irqs for printing at all. So what should I do - what is the "correct" way to set up my printer?
