They were the Intel D525MW boards, in a box made by ARK, a subsidiary of Intel. Running an RTAI patched kernel, wit hyperthreading disabled an a kernel argument of "isolcpus=1", the IRQ latency is about 2 u-s at the halfway mark on the bell curve. > > What machinery?

I am of that same opinion, as long as the battery doesn't explode I'm fine. That OEM battery is now north of a decade old so I fully expect the in-cord psu will upchuck trying to charge it one of these fine days. > > You then maintain your own local mirrors of the repos you need? > > I set up a 5 GB HTTP proxy and hosts entry in IPCop, and added a line > to /etc/apt/apt.conf.d/70debconf in each machine: > > Acquire::http::Proxy "http://proxy:8080"; > > > Using amanda here, which has the bare metal recovery covered. > > Small drive is relative, it will be a 1T Seagate thats about a year > > old.

If I need an offsite, that event will probably coincide with my demise. At 80, I am well aware that waking up in the morning is an excuse to celebrate. ;-) > 3.

At this late date, I think the one box does it all is ok. The wife will probably crawl under the desk and power down the room by pulling line cords when I am gone. And has no interest in learning the technical stuff. So if I am not here, its all moot. > David Cheers David, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
