I could not find any information on this controller.
It has some settings silkscreened on the controller but not all.
I can not get the secondary IDE port to work.
Some controller setting must be conflicting with it.
Are you trying to put a hard drive to the secondary channel or just optical drive?
If the bios doesn't have support for secondary channel, you need a driver to detect the extra hard drives.
I tried a CD-ROM drive but none was detected. So I tired a secondary hard-drive on second IDE channel but none was detected by the BIOS.
Yes, I think the bios supports multiple IDE channels. The primary hard-drive was detected fine so was the floppy drive, serial ports and parallel port. I disabled the game port as I usually use the game port from the sound card.
I need the manual for jumper settings.
