I cant comment too much with me being a complete newbie to scsi hard drives and controllers, but just yesterday i finall received my tekram 390u2w card along with my Atlas II 10k drive i have, took me a good while trying to figure it out with setting the drive up , basically my main obstacle was actually getting the drive partitioned and formatted believe it or not.
The controller was dead easy , basically a case of just installing and booting up and getting into the bios it has which seems pretty straight forward , then i turned the pc off and then connected up my hard drive with the correct cable/terminator and plugged into the correct port on the controller card.
after i had booted up and the drive was detected correctly with its id # configured etc i then started running into my probs i spoke of earlier , i tried to install the aspi drivers and tfdisk files but wouldnt load onto C: due to the fact it didnt detect a drive of any type , in the end i ended up booting using the win98 boot disk and then fdisked/partitioned and then formatted C: drive , once done then i went back and then tried what the manual said and everything worked great onwards
