5.4 Error Reporting
This section documents the types of system bus error conditions monitored by the SDS2 Server
Board.

5.4.1 Error Sources and Types

One of the major requirements of server management is to correctly and consistently handles
system errors. System errors on the SDS2, which can be disabled and enabled individually, can
be categorized as follows:
• PCI bus
• Processor bus errors
• Memory single- and multi-bit errors
• General server management sensors, managed by the Sahalee BMC

5.4.2 PCI Bus Errors

The PCI bus defines two error pins, PERR# and SERR#, for reporting PCI parity errors and
system errors, respectively. In the case of PERR#, the PCI bus master has the option to retry
the offending transaction, or to report it using SERR#. All other PCI-related errors are reported by
SERR#. SERR# is routed to NMI if enabled by BIOS.

5.4.3 Intel® Pentium® III Processor Bus Errors

The HE-SL supports all the data integrity features supported by the Pentium Pro bus including
Address, Request and Response parity. The HE-SL always generates ECC data while it is driving
the processor data bus although data bus ECC can be disabled or enabled by BIOS (enabled by
default). The HE-SL generates MIRQ# on SBEs (Single-bit errors) and generates SALERT# on
