Hello all. Today I replaced OpenSuSE with OpenBSD 5.0 on my HP ML 570 G2 server. The system includes to memory boards for RAM. One board has 8 gigs, and the other has 4. The power on self test sees 12 and initializes 12, but after the server boots, OpenBSD appears to only see 4. I believe this relates to 32 vs 64 bit, but I'm not positive.
The version I installed was i386, not amd64. The processors are Xeon MP 2.2Ghz which only have 32 bit instruction sets, which is why I chose i386. Here is a link to the processor specs that show this: http://ark.intel.com/products/27300/Intel-Xeon-Processor-2_20-GHz-2M-Cache-400-MHz-FSB The FAQ mentions a trick for utilizing more RAM when all of the RAM isn't seen using boot.conf at this link: http://www.openbsd.org/faq/faq4.html#InstProb However, this is for such a small amount of RAM in the given example, that I'm not sure this would work for me. Can anyone confirm that I'm pretty much stuck with only being able to utilize 1/3 of the full potential, or whether the above trick might actually work (using appropriate size values, of course)? Thanks for any help on this!
