Comment (by hunnia1):
I did not know that nforce AHCI is being worked at. :-)
So more details:
CPU 2core amd64 (Athelon)
1 pata IDE Master/Slave. Master DVD Drive, slave empty.
4 channel SATA. The first 3 are used. I will designate them sda, sdb and
sdc (Linux designation)
For test Haiku is on a USB stick recognized as sdd.
If SATA is configured as IDE, all disk and partitions are recognized.
Haiku is installed on /dev/sda(2) and works properly.
If SATA is set in the AHCI mode. Haiku on USB boots see attachments, but
only the USB stick is recognized by the disk program.
Accidentally I found out that if I boot with the SMP disabled (SATA is in
the AHCI mode) sdb and sdc plus the DVD drive recognized. All partitions
are shown correctly. sda is not seen by HAIKU. Playing with the other safe
boot options does not change it. Nor is there a change if in the bios I
change boot order.
Unfortunately since Haiku is installed in sda, I cannot run it from hard
rive in the AHCI mode. So nforce SATA (MCP78S) almost works.
