I just bought an Ultra ATA/100 Raid IDE Controller Card. The chipset it uses is CM649. I wonder if anyone heard of it. I am just using it to add an extra harddrive onto my system, so I only installed the IDE drivers but not the RAID drivers on my dual OS system.

This link provides addition information regarding with my IDE Controller Card.

WinME and WinXP Prof. worked perfectly and detected my extra harddrive without a problem.

The problem is that when I use a bootdisk to boot into DOS when I first turned on my system. DOS cannot read my extra harddrive. Is there anyway to fix this? or there's no way? I want to access to my extra harddrive through pure DOS. I tried to look for a DOS driver, but no luck. Anyone has any advice or comment, feel free to reply!
