@ -435,6 +435,10 @@ The MiataGL has a faster PCI-PCI bridge chip on the PCI riser card than
some of the MX5 riser card versions. Some of the MX5 risers have the *same*
chip as the MiataGL. All in all there is a lot of variation.
Not all VGA cards will work behind the PCI-PCI bridge.
Workaround is to put the VGA card 'before' the bridge in one of the 64 bit
PCI slots.
Sound:
Both MX5 and MiataGL have an on-board sound chip, an ESS1888. It emulates
a SoundBlaster and can be enabled by putting
