get same F1 message. But, have put CDRW in right way( red wire to the right of the CDRW as one looks at it from the rear). Also I've inserted the motherboard connection end of the cable with the red wire at the bottom( as one looks at the Mobo ). Interestingly, there are the usual two primary/secondary ATA 100 "plugs" on the mobo but there are also two more( not labelled as far as I can see, but these ones have the floppy insertion "plug" next to them). From my, naive, point of view, I have 4 insertions that could be primary/secondary IDE "plugs" to use. Whichever I use, I have the same problem, tho'.
