And I've had no worries.
Sata Dvd burner is Sony's AD-5200S connected to an ich10r, mobo is Ga-ep45-ud3r with Bios F4. OS are W2k heavily HfSlipped to December 2007 as well as Xp with integral Sp2.
These combinations worked:
- Bios in P-Ata compatibility mode, W2k with no F6 driver; boots abnormally slowly;
- Bios in S-Ata Ahci mode, W2k with BlackWingCat's Ahci/Raid driver used in F6 mode; boots much faster;
- Bios in S-Ata Ahci mode, Xp with Intel's iastor v8.7 used in F6 mode; boots very fast.
