I attempted to install a Kingston 120 SSD as the primary drive and that failed. The system BIOS and DOS would see the SSD as the primary boot device okay, however, XP would only see it as the secondary drive. While attempting to install XP with the SSD as the primary drive, the XP install procedure would halt with a "HD not found" message. The SATA/RAID drivers loaded without an issue, but the XP install routine refuses to see the SSD during the install phase. I spent way too much time trying to solve that issue. As an afterthought. it may be a blessing in disguise, in that the A7N8X-E is a non-ACHI motherboard and there is a possibility of TRIM issues down the line. I plan to further isolate the problem by attempting to use a SATA HD and see if it's just a Kingston SSD issue. In my experience, there have always been a few 'gotchas' when trying to retrofit new technology to older systems.
