Hi,
sorry for bad english and.... it's the first post for me try to understand me....

I have an embedded Intel server raid with server Acer altos g320.
Two sata disks in Raid 1 mirror configuration.
The fedora core 5 load an ahci driver to see the disks but nothing for the mirror. (sda and sdb is listed as singles drives).
The chip of the enbedded Raid is LSI ICH6R (probably a Megaraid sata 150-2).

What i can do to load the correct Megaide driver during installation?

Saying its embedded Intel RAID makes it sound like hardware RAID rather than software RAID. if it is hardware RAID you typically configure the RAID during in the BIOS. By default it likely has no RAID devices configure which is why you're seeing both drives in Linux.

On my Dell and IBM systems that have RAID controllers there is usually a prompt to enter the RAID setup (BIOS) somewhere during the boot after the prompt for the motherboard BIOS. (Something like Ctrl-A for RAID setup and F2 for motherboard BIOS.)

Since you're saying it is "embedded" it may be the RAID config is done in the motherboard BIOS itself.

This is all BEFORE you would put in a CD for Linux or Windoze or any other OS. Once you've configured the hardware then you do the Linux install at which point it should see the RAID device you configured as a single drive (assuming you'd configured both drives into a single RAID device).

I have already configure the raid in the bios controller.

With the acer cd driver i try to install win2k3server on the mirror Raid1 with succes.

With the megaide driver 5.08 from supermicro ftp site i can install RedHat 9.0 in the mirror Raid1 partition.

But the fedora distribution 4 and 5 load only the ahci driver.

The fc4 have a megaide driver version 5.09a included but if i load this i don't see the Raid.
