Yup! We just posted a new revision of the BIOS Optimization Guide! The new Revision 7.6 BOG comes with the following updates :- - Auto Turn Off PCI Clock Pin - Boot To OS/2 - CPU Hyper-Threading - DBI Output For AGP Trans - Disable Unused PCI Clock - Hyper-Threading Technology - Primary Graphics Adapter - Delayed Transaction - PCI 2.1 Compliance - PCI Delay Transaction As mentioned earlier, one of the most important update is the PCI Delay Transaction BIOS feature. My original contention that it is an ISA-bus specific BIOS feature is wrong! I have been doing some intense research on it for the last few weeks and I have finally come up with the final word on PCI Delay Transaction! So, please pass the word along. It is important that everyone's assumptions about this BIOS feature be corrected. And if anyone of you know of any new or uncovered BIOS options, please feel free to post them here according to the format stated there. That will really help me process them faster. Thanks!
