Intel® Server Board SE7520BD2 Technical Product Specification Other Useful Information
Revision 1.3 Intel Confidential 161
8. Microsoft Windows* 2003 and Microsoft Windows* 2000 32-bit
version cannot recognize 6GB system memory
Problem When a customer uses a total of 6GB or more memory on an Intel®
Server Board SE7520BD2 under Microsoft Windows* 2003 server
edition or Microsoft Windows* 2000 operating systems, all of the system
memory is not recognized.
Implication This is an issue caused by Windows operating systems and an Intel®
Server Board SE7520BD2 hardware or BIOS issue.
Workaround Edit the boot.ini file under the Windows system directory and add
the PAE command to fix this issue.
The content of the boot.ini file should be similar to the following:
[boot loader]
timeout=3
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows
Server 2003, Enterprise" /fastdetect /pae
C:\="Microsoft Windows"
Status
The workaround (specified above) is the only fix.
9. Onboard CTRL <C> RAID 0,1 creation appears to be slow and
limit the number of RAID configurations.
Problem When building a low-level RAID 0, 1(mirror) configuration it appears to
be very slow and never complete. Also, there appears to be a limitation
on how many RAID devices a channel can have. Specifically, a mirror
can be created on both cables but only one mirror for the whole
controller.
Implication A user might start building a RAID configuration, but not let it finish. If
the system is rebooted before the configuration is completed the
onboard LSI* 1030 controller is even slower than if the RAID
configuration was left to complete over several hours. Typically, it takes
1 hour for 10Gigabytes to complete building with the onboard CTRL
<C> application. For instance, this means that for two 70Gigabyte
drives configured in a RAID level 1 configuration it will take 6-8 hours to
complete. It is even slower if a 3
rd
drive is configured in a “hot spare”
mirror configuration.
