Not a big problem for small capacities. I'm thinking of e.g. someone
updating one cluster master with a small IDE device so that other
cluster members can pull their local storage from it. We have some nodes
with an IDE connector on the outside, originally to connect a CD.

An alternative is a USB solid state "disk" - these work nicely with
Linux, and I take it that there are no "spin-up" issues. :) USB has the
advantage of being (hot) pluggable from the back (and occasionally
front) of just about *any* box. Does LinuxBIOS play nicely with USB? It
also has the advantage, for servicing, that one can connect e.g. a
keyboard or a laptop via a USB-USB "net". Maybe e.g. a palmtop via its
USB cradle?

Thanks for the warning, but - "usual" differences? The archives of this
list seem to yield a miscellany of rants from Ron about ASUS brokenness.
Are the idiocies random or is there a warped logic? I also note Ron's
comments that once working, ASUS boards are quite good. :) I would send
you the result of /sbin/lspci, but unfortunately, said box has now died,
so we'll have to wait until it's fixed/replaced. It's an ASUS CUSC rev
1.05, for what that's worth.

http://www.digit-life.com/articles/asusterminator gives a description.
It would be a great development box if we can get it to work. The case
is nicely designed, and the board very compact. No BIOS socket (to be
expected, I guess), so no easy addition of a DoC. In this case, maybe a
skinny LinuxBIOS (with Etherboot?) in the flash which boots a kernel on
some other media would be a start.
