Description of problem:
Boot kernel from Fedora Core Test 3 doesn't work on Abit KV8-MAX3
Chipset VIA with Serial ATA drive. During the SCSI drivers loading the
installer always stops. Especially during the sata_via driver loading.
This problem always occur in the Fedora Core versions.
Hard disk: Seagate 80GB Serial ATA
Mainboard: Abit KV8-MAX3 with chipset VIA
Processor: AMD 64 (Fedora Core uses under 32-bit or 64-bit architecture)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot Fedora Core Test 3 installer
2. Load SCSI -> sata_via
I have the same problem with a Dell Precision 370 using the Intel 925x
chipset. The ata_piix and libata modules are loaded but no disks are
seen. I'm using FC3RC2 for X86_64.
To be clear, the installer informs me that no disks are found and
quits. Nothing crashes or hangs.
Turns out to be a BIOS setting. I ordered the machine with two 80GB
disks and Dell set the BIOS SATA configuration to RAID. Setting it to
The problem with the above solution is that after I make the BIOS
changes, my windows XP won't boot - that is until I change the BIOS
settings back. That means that every time I want to boot the other OS,
I have to adjust the BIOS. It is slightly inconvenient - especially
when I need to reboot the machine remotely...
An additional problem with the solution listed above is that setting
the BIOS to Combination mode in effect enables Parallel-ATA emulation
of the hard drives, resulting in a performance drop.
Possibly a better solution is to set it to RAID Autodetect/ATA
instead. This will allow the drives to operate in native SATA mode.
See http://linux.dell.com/storage.shtml for more information.
Caveat: You can't use the "hardware" RAID (its actually the
driver/firmware that performs the RAID functions)... Linux software
RAID is a good option though.
The root cause of the problem is that Dell ship the 370 with the SATA
operation mode set to RAID Autodetect/AHCI as default. The kernels up
to and including FC3 (and possibly the very latest kernel.org one, I
don't know offhand) don't have the AHCI support needed for this to
