Right, but why reinvent the wheel. If you need a card to do something and there is something on the market, you can write drivers for it and use it. There is a fast ethernet card for the Silicon Graphics Indigo^2 that is made by Phobos. Wait, actually it is an off the shelf 3com EISA fast ethernet card with Phobos drivers, and a reprogrammed identifier... because SGI boxes aren't as popular, you end up paying a couple grand for the driver. > Over the summer Atheros (makes the radio modules in the dlink and linksys > wireless stuff) took the groundbreaking step to release a "sort of" open > source driver for their hardware, but this is not the norm at all.

Speaking of, we are running 10 PCI sound cards in a single FreeBSD machine... people on here have mentioned this... we use a PICMG SBC on a backplane with 19 PCI slots. Got two fo them for $125 off of ebay. So there are solutions for tons of PCI FXO cards, but a channel bank would be cleaner. pictures: http://users.757.org/~ethan/pics/geek/soundcard_champion/ > So in summary, unless you happen to have some pipeline of information > coming from a winmodem manufacturer, making it into a linmodem let alone > another specialized telephony device is anything but trivial, unless it > happens to be based on exactly the same chips and reference designs as the > software you have is for.
