PC can not secondary IDE chanel

I recently built a PC based on a ASUS A7A Mobo with a 266 FSB 1.2 Gig cpu.
the PC does not see my re-writer (Secondary master) although it seems to work, but any drive on the secondary slave connection will not work at all, the BIOS does not seem to see either secondary drive, is this a hard ware problem or a bios problem?

 

make sure jumpers are set properly and maybe try another ide cable

 

already on my third IDE cable and the MoBo is a "jumper free" bord, the master/slave jumpers on the back of the drives is set correctly

 

cable has to be plugged in red stripe to pin 1 on both the drives and the motherboard, sounds like it's wrong.

Bios should be set for secondary ide cdrom or autodetect on both the master and slave channels.


One device must be jumpered master and the other slave

If that still doesn't work, swap the master/slave on the drives, some won't install as master sometimes.
