This includes new code by Collins Chen of Acer to support SPD in a DoC configuration. The code builds a bios fine but I have not had a chance to test it yet. The ASUS CUA will no longer work because the new code supports SPD and the ASUS CUA has a broken SMBUS (surprise!). The fix is to never buy ASUS motherboards. Motherboards that do seem to work are the pcchips m754lmr and a similar mainboard made by amptron. Actually I get the impression these are actually made by somebody else and are the same part, but I'm not sure. ron
