SCSI termination. This has been giving me the big headache. I though I have a good understanding of SCSI termination, but now I am confusing like hell.
I have a Gigabyte board (model GA-6BXDS) with dual channel UW SCSI with Adaptec built in chip set (AIC-7895). The manual is almost clear tell you how to set up in the BIOS for most of the case except in my case (pretty ODD, isn't).
This is what I connect into my computer
a. Plextor 4x12 recorder in channel A (50 pin)terminated in Plextor device.
b. Plextor UltraPlex 40 Wide in channel A (68 pin)also terminated in the device itself.
c. Two UW hard drives in channel B with the last drive terminated.
This is the spec and opitions in my SCSI board
1. Channel A has both UW (16 bit/68pin)and Narrow (8bit/50pin) connectors (one each).
2. Channel B has only one UW connector (16 bit).
3. The options in BIOS for channel A are LOW Byte, High Byte or Disable
4. The options in BIOS for channel B are Enable or DIsable.
5. Also after it passed the POST, you can press <Control -A> to get into SCSI set up utility to set further parameters for the SCSI devices. Every Adaptec SCSI has this set up utility. This has the option to set :Automatic, LOW=OFF/HIGH=OFF, LOW=OFF/HIGH=ON, LOW=ON/HIGH=OFF or LOW=ON/HIGH=ON. For some reason I cannot set to automatic.
My questions is what do I need to set up in questions 2, 3 and 4 for my case. Thanks all for the inputs.
