If you have an ide disk on your computer, then you can't enable the scsi bios. If you boot with the scsi disk, you can't use IDE with it. If you have an ide disk, do not boot from the scsi but from the ide. When windows manager sees the "ghosted" then your card is working ok, the disk is not formated correctly which is why the other scsi disk shows up. I had the same set of probs with my 2940 and darned if I can remember what I did. I think what I did was to boot it up on a computer as the only drive and then started to install the os so as to format it and it then worked. There is a more official way but one of the others will have to tell you how to do it. I also find I have trouble with having both external and internal peripherals on the same card, but that might be because of the 50-68 pin problem previously mentioned.
