On a Windows XP desktop, I have connected a Zip 250 drive (Z250ATAPI) to the motherboard's integrated J-Micron eSATA/PATA controller. The IDE cable has 2 connectors but only one is used.
It seems the device isn't recognized by the BIOS, as I cannot select it in the boot order menu. If I plug a CD drive in the same connector instead, it works normally. Windows does not see anything either, but if I connect both CD drive and Zip drive together, the CD drive is functional, and I get 50% of CPU usage due to interrupts. The controller is set to IDE mode. I have tried every jumper position and always got the same result.
I have browsed everything in the BIOS' menu, but nothing seemed relevant to this situation. What could be the issue ?
