Erich, Yes, one end of R8 is IDE pin 30 and the other is pin 62 on the ATA controller. Perform a continuity test from pin 30 on the IDE connector to the ends of R8. This will tell you which end is which. If you're going to use both ends of R8, the switch/jumper configuration shown in the middle of ATA_Modification.png is suggested. -- Mike Noyes <[EMAIL PROTECTED]> http://sourceforge.net/users/mhnoyes/ http://leaf-project.org/ ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ leaf-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-devel
