I tried to change the configuration of a compatible sata in bios to AHCI, but my hard drive is not detected.
I do not have a smart array controller. I do this AHCI features need smart array controller? I've been looking for a reference, but did not find.

Any suggestions?

This result:
# hdparm -tT /dev/hda5

/dev/hda5:
 Timing buffered disk reads:    8 MB in  3.08 seconds =   2.60 MB/sec

First of all it should report /dev/sda and not /dev/hda

It is a horrible speed for modern disks.


Modern SATA disks show around 50-80 MB/Sec

I am sure ide0noprobe=no (or zero -- check docs) in the kernel mline
will surely speed up in addition to other suggestions will
dramatically speed up.

As will setting the operation mode in mode in BIOS from compatible to
SATA. First thing i do on all HP servers when they are shipped.
