BIOS Notes: Has BIOS files earlier than the Release 05 (12/04/2003). They are Release 03 (date 11/17/2003) and Release 04 (12/02/2003). The latest BIOS release is Release 07 (03/19/2004). My board originally had the Release 03 BIOS, which was interesting to say the least. Release 03 and 04 are not found on Biostar's site, and interestingly were retrieved from DriverGuide's site. They are legit files, AFAIK.


Front Panel Audio Connector and Onboard Sound:
Since owning this board in 2011 and no sound until then (December 2018), I finally do have sound from the onboard sound chip. If no front audio panel is present, you would have to add two jumpers to the front audio panel connector on pins 5-6 and 9-10, otherwise the onboard sound will not function on the rear audio panel's green line out jack.
