sound problems on Toshiba

[Frederic DUBOUCHET]

I'm triing to have my sound cart work on a Toshiba laptop. And I found 
some hints on the net talking about an option called PNPBIOS but nothing 
left on FreeBSD 5.2! what about it, does it still exist with another 
name? can somebody help me?

my laptop is a Satellite 5100-503 (I don't remenber the Us model 
corresponding to it...) the sound card is a Yamaha AC-XG...

thanks!
