I'm trying to figure out what is the right driver to access the CF. The HW configuration is as following: The CF is connected directly to MPC8541 CPU (PowerQUICC III, Freescale), via local bus. It is connected in Memory Mode, with 8-bit interface. The questions I have: 1. What is the appropriate driver? Since memory mode is PCMCIA-compatible PC Card ATA, I assume it is ide-cs. Is it right? 2. The card doesn't issue interrupts in this mode. I got the impression the IDE driver relies on interrupts. Does it make it unusable for accessing a CF in Memory Mode? Most grateful for your help, Michael
