Dear all,
I have one question about the AHCI support in current EFI BIOS...
Before when we plug external storage card(Ex. PCie-SATA) and attach one SATA drive, BIOS always invokes the Option ROM on that card to do some initializations and provide UI to config during POST...
My question is: Does current BIOS natively support AHCI for this kind of external card ?
* here "natively" means EFI BIOS does NOT invoke the Option ROM and can fully configure this card itself then enable AHCI function ?
or current EFI BIOS just natively support Intel or AMD's AHCI controller only ?
Regards,
