PCI Express I/O Expansion Board—Adds six optional slots
PCI-X/PCI Express I/O Expansion Board—Adds five optional slots
WARNING!
in the system. Devices which were not allocated requested resources may not operate
properly.This occurs during the I/O configuration phase of POST, after the System ROM has
allocated most of the available memory for some PCI devices, leaving insufficient memory for
PCI devices that have not yet been configured.The above message is an indication that the
HP ProLiant DL980 G7 server has encountered this MMIO limitation and does not indicate
an issue with the server. It can occur when the I/O configuration of the server demands
resources beyond those which the platform architecture allows.This message is an indication
that the HP ProLiant DL980 G7 server has encountered this MMIO limitation and does not
indicate an issue with the server. It can occur when the I/O configuration of the server demands
resources beyond those which the platform architecture allows.If some PCI devices are not
allocated memory and the warning message appears during POST, perform one or more of
the following potential workarounds to allow the remaining PCI devices to receive their
requested memory allocations:If the server operating system documentation states that it requires
2GB (or more) of memory below the 4GB address boundary, do not perform Step 1 below
because it may result in operating system boot failure.If the operating system documentation
does not specify its memory requirements below the 4GB boundary, the Step 1 procedure
below may be attempted. However, if performing Step 1 results in operating system boot
failure, perform Step 1 again and change Memory Mapped I/O Options to the default value
of 2GB of Memory Mapped I/O , and then perform Step 2 below:
1. Change the MMIO Settings in the ROM-Based Setup Utility (RBSU).

g.
2. If the warning message continues to appear, ensure that all slotted PCI devices are using
updated firmware and drivers and reboot the server.
3. If the warning message continues to appear, determine which adapter is least critical for
the operating environment and remove or disable that adapter. Repeat this step until the
server completes POST without displaying this error message.
64 Removal and replacement procedures
There is not enough available PCI memory to allocate to all devices installed
Boot the server.
Press the F9 key during POST (when the F9 prompt appears).
Select Advanced Options.
Select Advanced System ROM Options.
Select Memory Mapped I/O Options.
Change the default selection of 2GB of Memory Mapped I/O to either 3GB of
Memory Mapped I/O or Automatically configure Memory Mapped I/O.
Reboot the server and verify that no warning messages appear during POST. If the
operating system will not boot, perform Step 1 again and reset Memory Mapped
I/O Options to the default value of 2GB of Memory Mapped I/O .
