The current Compaq X-Caliber Megacell Initiator does not support fast back-to-back PCI Transactions when in PCI 2.2 mode. This was the main mode that I wanted to use. Has anyone tried to modify the code to support this case? Was it easy/impossible? Thanks- Brent Barr Senior Design Engineer F5 Networks 1322 N.
