ECS does updates. visit their site, they have plenty of those so called updates.
if you want widescreen support for your onboard VGA visit our download site. read the sticky thread in the VGA section to find the link.
the driver for chipset and vga are available at www.sis.com
the driver for sound is available at ECS' site or at the site of the codec manufacturer (like CMI or Realtek). if you don't know what i'm talking about just head over to ECS and get the driver there.
If you email me include [WIMSBIOS] in the subject.
