I installed an Adaptec AHA-2940 SCSI Host Adapter board into a vacant PCI slot in my PC to control an old SCSI Scanner. I only have one SCSI device hooked up and the scanner (which is set to SCSI ID #2 on the back of it and is properly terminated) works very well, but the 2940 also seems to cause four non-existant CD Drive icons to show up in 'My Computer'. I only have two physical DVD drives in this computer (which aren't even SCSI devices), but six CD drives are showing up in My Computer. I tried to uninstall the four extra CD drives thru Device Manager, but they keep coming back every time I reboot. So, I must have the 2940's setup settings (accessed via Control-A upon bootup) wrong and I can't figure out how to eliminate the four ghost CD devices from Adaptec's documentation. Upon booting up the computer the Adaptec startup sequence also times-out looking for SCSI devices (which, I think, probably takes longer than it must because of my incorrect 2940 settings). Can anyone please tell me the proper Adaptec 2940 startup settings to get rid of the four fake CD devices, stop the startup time-out error and to streamline the bootup process?
