So I have a DFI X48-T2R motherboard running XP Pro SP3 + latest updates and all seems to be working just fine.
The problem I have is with hot swapping SATA drives inasmuch as if I boot the system with a drive plugged into the SATA port. I can unplug the drive and it disappears from the XP explorer and if I plug it in again the it appears in the XP explorer windows and I can read and write to the drive.
However if I boot the system without the drive plug into the port I am using to hot swap then it will NEVER work. Inasmuch as I can plug the drive in but it never appears in the explorer windows or in Disk Manager.
I have turned AHCI on in the bios (NONE RAID) and when installing XP I loaded the driver “ICHP SATA AHCI DeskTop ICH93” at F6 time. I have also loaded the latest iata96enu.exe drivers from the intel web site and have install them but the problem is the same.
I have a Dfi NVidia based MB and hot swap works perfectly on it. It just does not seem to happen with intel ICH93
