Limited RAID Support in Linux Operating Systems

the on-board ICH10R controller, but RAID is supported through the LSI3041E HBA.
Error Message Appears in Red Hat 5.1 and 5.2 Operating System
The following error messages might appear in dmesg and /var/log/messages:
kernel: ata2: spurious interrupt (irq_stat 0x4 active_tag -84148995 sactive 0x3)
This issue is under investigation.
System Fails to Perform PXE Installation of Linux Operating Systems
The system can successfully PXE boot from the on-board Intel 82567LM-2 NIC, but Red Hat
and SUSE installation setups fail to detect the NIC. Current released versions of Red Hat and
SUSE do not support the Intel 82567LM-2 NIC.
Please wait until RHEL 4.8, RHEL 5.3, SLED10 SP3, and SLED 11 for built-in 82567LM-2
Ethernet support or perform the following workaround.
Workaround
Install a PCI/PCIe NIC card, and then PXE install from the new NIC.
