|As StuartS has stated, you need to set the BIOS to boot to CD before hard drive. If the disk in the CD drive is not bootable you will get the same results, which it to bypass the CD. That is why I asked the source.|
I could not find that model motherboard on the Biostar site. I am guessing the board was made for an OEM vendor like Gateway, etc. I believe the board is based on the nforce 2 chipset series. As such, you will not have any settings to run the SATA hard drive in an IDE compatibility mode. If you have a floppy drive installed you can supply the SATA drivers that way or you will need to slipstream them for at least WinXP and possibly Server 2003. I think there are issues with Vista on boards using the nforce 2 chip sets and you may not get Vista to work at all.
Honestly, the simple solution at this point is to use and IDE/ATA boot hard drive.
What is the history of the motherboard. BTW, I am assuming the number in your header is the motherboard in use?
