I have not seen an answer to this question and the manual cannot be downloded on this motherboard from Chaintech. why??? I purchased a large 300GB SATA drive. I removed my original 30 mb master drive (IDE) and substituted the new 300GB monster. The 60G slave HD was left where it was connected to IDE plug#2 as I wanted to still use it as an extra storage device. I wanted to install Win 2000 freshly to clean things up but no matter what I did in BIOS (including loading defaults) the new system refused to recognize the CD ROM or DVD drive. I eventually disconnected everything from IDE plug#1, connected the SATA wire to SATA socket#1 on the MB and it recognized the CDROM/DVD right away. WIn 2000 is installing as I write. Problem is that it leaves me unable to access all the data on the old 60G IDE drive. Using the SATA plug on the motherboard, it seems as soon as I connect anything to the IDE1, it disables access to the IDE2. What's the solution? I cannot daisychain more devices to the IDE2, so I'm stuck. Suggestions/fixes? Thanks in advance
