BIOS Issues
System Does Not Detect Supported HBA Card
During Bootup Process (6272514)
If a supported host bus adapter (HBA) card is plugged in to Slot 1 (on a Sun Fire
X4100 server) or Slots 1-4 (on a Sun Fire X4200 server), the card is not detected by
the BIOS during the bootup process.
Analysis
After the BIOS scans the network interface cards and SAS, the BIOS runs out of
address space for the option ROM and cannot scan the card. However, the card is
detected at the OS level and can still be used.
Workaround
To boot the system from an external storage device, connect the device to a
supported HBA controller installed in Slot 0.
BIOS 36 Improves Stability of DIMMs By
Disabling PowerDown Mode
Sun Fire X4100 and Sun Fire 4200 DIMM’s (in particular, Infineon DIMMs that use
IDT registers) might sometimes have a problem going in or out of the PowerDown
mode and might subsequently trigger uncorrectable ECC errors that can lead to
system reboots.
Workaround
Upgrade to BIOS 036 or later. BIOS 36 is included with Software Release 1.2.1. For
instructions on upgrading to Software Release 1.2.1, see the Sun Fire X4100 and Sun
Fire 4200Sun Fire X4100 and Sun Fire 4200 Release Notes For Software Release 1.2.1,
