I have one HP Proliant DL320 G5p, where for some reason, the AHCI mode is not enabled. According to server specs, it should have AHCI/NCQ capability, but ata_piix module gets loaded during bootup, not ahci module. Any ideas how to enable AHCI mode? lspci output: # lspci 00:00.0 Host bridge: Intel Corporation 3200/3210 Chipset DRAM Controller (rev 01) 00:01.0 PCI bridge: Intel Corporation 3200/3210 Chipset Host-Primary PCI Express Bridge (rev 01) 00:06.0 PCI bridge: Intel Corporation 3210 Chipset Host-Secondary PCI Express Bridge (rev 01) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 02) 00:1c.2 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 3 (rev 02) 00:1c.3 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 4 (rev 02) 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 02) 00:1c.5 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 6 (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02) 00:1d.3 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 92) 00:1f.0 ISA bridge: Intel Corporation 82801IR (ICH9R) LPC Interface Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 4 port SATA IDE Controller (rev 02) 00:1f.5 IDE interface: Intel Corporation 82801I (ICH9 Family) 2 port SATA IDE Controller (rev 02) 01:02.0 VGA compatible controller: ATI Technologies Inc ES1000 (rev 02) 01:04.0 System peripheral: Compaq Computer Corporation Integrated Lights Out Controller (rev 03) 01:04.2 System peripheral: Compaq Computer Corporation Integrated Lights Out Processor (rev 03) 01:04.4 USB Controller: Hewlett-Packard Company Proliant iLO2 virtual USB controller 01:04.6 IPMI SMIC interface: Hewlett-Packard Company Proliant iLO2 virtual UART 02:00.0 PCI bridge: Broadcom EPB PCI-Express to PCI-X Bridge (rev b5) 03:04.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3) 03:04.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3) -- Veiko
