29. System BIOS may report POST error code 0x146 with the Intel® Xeon
Phi™ Coprocessor installed
Problem System BIOS may report POST error code 0x146 “PCI out of resource error”
when one or more Intel® Xeon Phi™ Coprocessors are installed with the BIOS
default setting.
Implication The Intel® Xeon Phi™ Coprocessor might not be recognized using the default
BIOS setting as it requires more PCI space.
Status This issue was fixed in BIOS release R02.01.0002 and later release.
Workaround Press F2 to enter BIOS Setup, change Advanced -> PCI Configuration -> Memory
Mapped I/O Size to 256G or larger. The value also depends on your system PCI
configuration.
30. The Intel® Xeon® Phi™ Coprocessor PCI Express* Card Status Sensor may
show "Unknown"
Problem When only one Intel
®
Xeon
®
Phi™ Coprocessor PCI Express* Card (MIC card)
is installed in the server system, the card status sensor “MIC 1 Status” or “MIC
2 Status” may show “Unknown” in Intel® Integrated BMC Web Console.
Implication Users may not get the correct MIC status in Intel
®
Integrated BMC Web
Console. There is no function impact to the server system. This issue doesn’t
happen when two Intel
®
Xeon
®
Phi™ Coprocessor PCI Express* Cards are
installed.
Status This issue was fixed in BMC 01.19.4926 and later release.
Workaround None.
31. The Intel® Xeon® Phi™ Coprocessor PCI Express* Card sensors numbering
may not be consistent with riser slot numbering
Problem The Intel
®
Xeon
®
Phi™ Coprocessor PCI Express* Card (MIC card) sensors
numbering may not be consistent with riser slot numbering on the server board.
When a Intel
®
Xeon
®
Phi™ Coprocessor PCI Express* Card is installed in the
server system, in Intel
®
Integrated BMC Web Console, the card sensor may
show “MIC 2 Status” and “MIC 2 Margin” if the card is installed on “RISER
SLOT_1” and “MIC 1 Status” and “MIC 1 Margin” if the card is installed on
“RISER SLOT_2”.
Implication Users need to read MIC 2 sensors for a card installed on “RISER SLOT_1” and
read MIC 1 sensors for a card installed on “RISER SLOT_2”. There is no
function impact to the server system.
Status This issue will be fixed in a future BMC release.
