DELL OptiPlex 755 XP SP2 installation BSOD
Just got DELL OptiPlex 755 (with STMicro TPM chip). It comes with Vista Ultimate.
When we tried to install XP SP2 from boot, just when windows starts, after loading setup drivers, we end up with BSOD crash with stop code 0x0000007B. Naturally, this stop code points to some issues with IDE controllers.
I looked into the BIOS and seen that we have a SATA hard disk. Fine. Next step is to look at which controller it is using. In this case by default it is set to AHCI (Advanced Host Controller Interface). I had my suspicions on this and changed this to use ATA and tried to install XP SP2. Voila! It worked!
