I just got a hand me down Compaq Presario S6200CL. Put a barebone XP install and updated basic drivers (video, network, etc). nothing fancy. got 1GB ram installed. Pentium 4 2Ghz. anyways, I have installed a SATA expansion card, that previously was in another hand me down PC that worked with no problems. I installed the drivers with no problems, and Device manager says its working fine. Problem is, the SATA HD I have connected isnt showing up in Disk Manager. I went to my bios, and what do you know. There is not one single thing listed anywhere that says anything about SATA or RAID or anything. So i goto HP website, see if there is a BIOS update, and the only thing listed on the website for this computer (as far as BIOS updates go) tells me "cannot update bios, please contact customer support if the issue continues." So im wonderin if this motherboard even supports SATA drives or not. Anyone that can help me is awesome, becuase this will make the 3rd hand me down computer that basically doesnt work for my needs and my frustration is growing.
