ChangeLog

The time has come...

Recent Linux kernel contains native PCI driver for YMF7xx chips.
You should use these driver other than my legacy driver.

About `ymfsb`

This code enables you to use your

YMF724[A-F]
YMF740[A-C]
YMF744
YMF754

chips based cards in Linux operating system . These chips are shipped from YAMAHA and cards containing these chips are sold in low price (about $10 - $90 in Japan ).
With this driver, your card will act as "SoundBlaster Pro" compatible card. It can only play 22.05kHz / 8bit / Stereo samples, control external MIDI port.
If you want to use your card as recent "16-bit" card, you should get Alsa or OSS/Linux driver. Ofcource you can write native DS-XG driver for your cards :)

This code references YAMAHA's sample codes and data sheets.
I respect and thank for all people they made open the informations about YMF7xx cards.

And this codes heavily based on Jeff Garzik <jgarzik@pobox.com>'s VIA 82Cxxx driver (via82cxxx.c). I also thanks him.
