Sound is OK - a bit crackley
SATA works fine (if you only have SATA disks you'll need to bootstrap a kernel that recognises SATA somehow - I used a temporary PATA boot disk)

LAN is good works well with ALSA

Not used firewire

Not used USB but they detect OK

Have had no issues what so ever! AGP is running at a blazing 8x (with an nvidia agp card). I disabled the onboard sound as I have a Audigy. Great board, the BIOS is a little weak (feature lacking), but over all, stable, fast, and recommended. I do not have a SATA drive so havn't been able to test that yet, assuming it works (based on the post previous to mine).

This is a good board, but it does have its problems.

1. The BIOS doesn't initialize/reset USB properly if the system (Linux) isn't shutdown properly, like with a crash or power failure. This is a problem since I have a USB keyboard (and mouse). The USB keyboard doesn't work with the BIOS setup or with GRUB. I have to have a PS/2 keyboard sitting on top of the case for these situations. Once Linux loads though, everything is ok. And if I then shutdown properly then the keyboard will work with the BIOS and GRUB.

2. The board doesn't seem to turn off completely when it's turned off. I have a USB keydrive on an extension cable and its light stays on even when the system is shutdown. This is probably to enable the various power-on features (from KB, mouse, LAN, modem...).

3. Most of the time the system doesn't even get to POST when turned on. The screen stays off (in power-save mode) and the floppy doesn't seek. I have to remove the power cable from the PSU, count to ten, and plug it back in. Possibly related to #2.

Other than that, it seems to be a good board. My Radeon 9200 (AGPx4) works well. I don't know about SATA, but the driver for it loads ok too. All the USB ports (six with the supplied expansion bracket) seem to work as well. The on-board ethernet is supported by the 8139too driver. The board supports APIC so I get more than the old 16 interrupts.

BTW, hitting Ctrl-F1 in the BIOS setup displays "advanced" settings, for when you know what you're doing.

Update: I recently had to use the on-board software when I swapped out my SB Live to another machine for a quick experiment. IT SUCKS! Ugh. It totally lacked any high-end response. It was very muddy and sounded like the speakers were inside the wall.

It works problem free, except the LAN which refuses to work at all.
