Check and be sure that your jumpers are set correctly for each drive on each IDE channel.
IMO.. I would have the HD on IDE 0 (master)
and the CD-RW and CD Rom on IDE 1 (master/slave)
you can invert the CD drives depending how the person wants it.
Verify in the BIOS that it sees all the drives.
Go into Windows and see if it sees them.
If not, try using the Add Harware Wizard or Device Manager.
If all else fails.. it could be the MOBO.
Syntax huh... I have a media reader and WUSB dongle from them.. not brave enough yet to try their MOBO's
