This is a copy of bug #152627. The problem still exists in the latest RHEL4 errata kernel (2.6.9-5.0.3.EL) The PCI IDs for the ATI IGP integrated SATA controller need to be added to drivers/scsi/sata_sil.c and the boot loader image needs to be updated so the installer recognizes this hardware. The PCI IDs in question are: 0x1002 0x436e "sata_sil" "ATI|IXP300 SATA" 0x1002 0x4379 "sata_sil" "ATI|IXP400 SATA" The linux-2.6 changeset in question is: http://linus.bkbits.net:8080/linux-2.5/cset@41e4b5df5jSP3VOlsSO6pnMqEBX79A I confirmed that the RHEL4 kernel works properly once these PCI IDs are added to drivers/scsi/sata_sil.c. I followed the same procedure as I described in bug #152627; recompiling the driver and creating a driver update disk to use with Anaconda. Everything worked properly. Sorry, I couldn't see any channel for RHEL4 beta packages when I log into the Red Hat network page. Otherwise I would have tried taking a look to see if this has already been committed for future RHEL4 updates.
IDs confirmed in kernel-2.6.9-6.37.EL (U1-candidate kernel)
