I have tried everything I know to fix this plus on-line suggestions for 5 days. Could it be the biosVer.1.8 ( it list the secondary but won't detect) or could it be the Nvidia nForce4-S(LI chip on The MSI K8N SLI/F, MS-7185 ? I've done the cables, jumpers, PSU, Memory, fix MBR, replaced the MBR, a slue of different drivers (those from MS, Nvidia and MSI). the only thing I found was, the secondary controller wasn't assigned an IRQ. I tried to assign it one, didn't work. I stripped down the unit to just the primary HDD,CD-Rom,and video card. I tried Windows 98 boot disk to "fdisk" Fdisk'' did not see the secondary. I've taken the motherboard out and looked it over at lease 6 times,front and back. Taken the fan of the nForce4 chip and looked and compaired it to pictures I found on the Internet "Looks OK" One deviation, there appears to be a drop of expoxy on one of the upper right connections. I've heard of Nividia doing that to prevent modifications. D-bracket lights are normal on the board. Device Manager says everything is working, even says all IDE are working. So there you have it, Men ! "Whats Up with this thing" ? Thanks, DaveC

Have you tried swapping IDE ribbons? It is entirely possible that you problem is an bad connection/ribbon.

It sounds to me like you may have a bad motherboard. If you arent getting and signal from the known good component to the motherboard then the only explanation can be a bad ribbon, motherboard or bios setting.

I forgot to mention, When I lost the secondary channel, it was like someone turned the thing off with a switch. No warning !!

Sounds like a motherboard then. If you it was working and just stopped without you changing any bios settings and you know its not the ribbon then it really is the motherboard. HDD drives give you a warning when going bad but other things typically are not so forgiving.

That's what I was afraid of . BTW, What I haven't done is "flash" the BIOS. I was waiting for the very last thing I might try.

If you want to do that check in the manual for your motherboard (usually can download if you do not have it still) and it will show you how to clear the CMOS. If that doesnt work you can go to the website of the motherboard manufacturer and download the latest bios files and update the bios (it should give instructions on how to do that).

To be honest though I really don't think that will help. If it was working and you didn't do anything to make it stop, whether in bois or not, it sounds like it is jsut dead.

Do you happen to know what controls the IDE channels, Is it the nForce4 chip or is there more. I know the CPU has to be in there doing something. Trying to find a flow chart to see what goes where.
