I did it as you mentioned, but When playmidi, it still have no sound output. Then I installed OSS/Linux 3.99.1i driver, when dmesg it says: "oss: Probing the hardware for MPU-401 (UART) failed." Which item in the bios setup configuration present the irq? >From clemens@xxxxxxxxxx Fri Dec 3 22:17:24 2004 SiS chipsets don't have MIDI support, but the LPC I/O controller has a MPU-401 compatible MIDI port. Use the snd-mpu401 driver, and specify the port address and interrupt that you've configured in the BIOS setup. The entries in your modules.conf/modprobe.conf shoud look like this: alias snd-card-0 i810_audio alias snd-card-1 mpu401 options i810_audio index=0 options mpu401 index=1 port=0x330 irq=5 HTH Clemens
