Intel® Server Board SE7520AF2 Installation Guidelines

6. Installation Guidelines

6.1 Windows

2000 Advanced Sever Recognizes Only 4 GB of

Memory.

Issue When using greater than 4 GB of memory, POST reports the total memory
present correctly, but Windows 2000 Advanced Server only sees ~4GB. The
total memory present reported by Windows was checked by bringing up the
System Properties window and verifying the total memory displayed on the
General Tab.
Implication Memory above 4GB not being recognized.
Workaround The /PAE option must be enabled in the ARC path in the boot.ini file in order
for Windows 2000 to recognize memory above 4.0GB (e.g.
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows 2000 Advanced Server"
/PAE /basevideo /sos)
Status No Fix.

6.2 Potential Data Corruption Manifested Under SuSE

Linux 9.1

Professional Operating System

Problem Intel found through OS stress testing that the IA32 and the IA32e versions of
the SuSE Linux 9.1 Professional operating system (kernel 2.6.4-52-smp) can
exhibit silent data corruption on server boards based on the Intel(R) E7520
chipset.
Implication Investigation determined the data corruption stemmed from a race condition in
reiser file system that ships with SuSE Linux 9.1 Professional OS (2.6.4-based
kernel). Although the reiser file system is the default file system used by SuSE
Linux; tests of alternative file systems supported by the OS have not
manifested this data corruption. All investigations and test results ascertain
that this anomaly affects the IA32 and IA32e versions of the SuSE* Linux 9.1
Professional OS. This anomaly is expected to be addressed by the OS vendor
on the SuSE Linux Enterprise Server 9 version when officially released.
Workaround None supported by Intel.
Status No Fix.

6.3 Tape drive shown as if 8 tapes are installed.

Problem When Quantum* Tape(DLT VS160) is installed in On-board SCSI. In some
cases, 8 tapes are attached in Windows* Device manager. Similar symptom
may appear in Netware* 6.5 sp 1, where 8 Tape devices may be seen in the
Device List.
