CPU or RAM is in no > way different. Oh, okay, this sort of thing is supported by industrial boxes? Interesting... Live and learn I spose ;-) (You're right, I'm not familiar with industrial boxes at all. My experience is with mostly desktop computers, laptops, and some entry-level servers) Hotplug RAM I could see would be possible, but hotplug CPUs? I spose if you've got a multiprocessor box, you could swap them one at a time, but my thinking is that this would cause issues with the OS as it wouldn't be expecting the CPU to suddenly disappear. Problems would be even worse if the old and new CPUs were of different types too. Hotplug RAM would also be interesting, but then again, I spose the procedure would be to alert the kernel that the memory area from byte X to byte Y would disappear, so it could page that out to swapspace. Anyways, I don't profess to be any hardware/software/kernel guru, I had never heard of this level of hotplug, and it struck me as unusual. - -- +-------------------------------------------------------------+ | Stuart Longland stuartl at longlandclan.hopto.org | | Brisbane Mesh Node: 719 http://stuartl.cjb.net/ | | I haven't lost my mind - it's backed up on a tape somewhere | | Griffith Student No: Course: Bachelor/IT (Nathan) | +-------------------------------------------------------------+ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQE/hr0OIGJk7gLSDPcRAl9CAJ0c+iU//ELVoO8czbezWgvd7UBzjwCeNApa ftZkG88NrefELUoGaEop+NI= =tTfj -----END PGP SIGNATURE-----
