AHCI CD-ROM driver for DOS (Developers)

posted by RayeR Homepage, CZ, 16.12.2009, 01:37

What this HP driver should exactly do? When I enable AHCI mode on my controller for my SATA drive I still can access it under DOS via INT13h extension (it's not emulated on low level as in IDE compatability mode so some low level tools cannot acces it). I think that any driver can't help when application will touch directly IDE IO ports. Or does it intended for PC without INT13h support in AHCI mode? And about performance... I tried to enable AHCI mode under WinXP-SP3 with latest intel drivers but I didn't get any significant speed gain. So I have AHCI disabled for compatability with Win98SE...
