I'd like to put FreeBSD on them. What facilities (if any) does FreeBSD have for: 1) Reporting the status of ECC memory (errors corrected, errors uncorrected, etc.)? 2) Responding to uncorrectable errors? 3) Mapping out portions of memory that produce repeated errors? It seems to me that, for an operating system that prides itself on server stability and performance, such features are a must. --Brett
