LSI Firmware, Service Processor, and BIOS Issues 21
BIOS 036 disables the PowerDown mode (self-refresh/low-power mode), per AMD’s
recommendation. Some DIMMs are susceptible to the noise induced when entering
and exiting the PowerDown mode. With the PowerDown mode disabled, the
probability of UE reboot is much reduced and the system stability increases.
System Connected to External Storage Device
Using PCI Card in Slot 0 Might Not Boot from
Internal Disk (6268877)
The system will not boot from the internal HDD if any external storage devices are
connected to a PCI card plugged in to Slot 0 only.
Analysis
This occurs because the BIOS scans Slot 0, which connects to the HDDs, before
scanning the embedded 1064 SAS controller.
The BIOS scans PCI devices in ascending order (from low PCI address to high PCI
address). The scanning priority is:
1. NIC
2. Slot 0
3. SAS
4. Slot 2
5. Slot 3
6. Slot 4
7. Slot 1
Because of constraints in the option ROM, internal HDDs connected to the
embedded LSI SAS controller might not be in the boot list if a PCI card is installed in
Slot 0, which connects to the external HDDs.
Workaround
Install the PCI card in Slots 1-4 instead of Slot 0. Slot 0 is the only slot that cannot be
used if you want to boot from an internal hard-disk drive in the server.
