These are the BIOS points that are important for me; most were left at the default values.
Hit F12 during POST to get the
boot menu, and pick Diagnostics.
While doing memory diagnostics, which probably maxes it out,
the case is hardly warm to the touch, but the fan is in its "noticeable"
mode and the machine (excluding monitor) is drawing 43W.
The fan is putting out a respectable amount of warm air.
The power brick is warm but far from hot, maybe 15C rise from ambient.
When the diagnostic tests the "High" fan speed, it is really noisy.
Random seeks: if you put your hand on it you can feel the disc motion, but
it is not audible at all.
While the long disc test is running, put media in the optical drive
and the card slot, because these are tested next.
All diagnostics passed. (It didn't include the graphics card.)
To exit from diagnostics, use the mouse and click the X (close) button
in the upper right corner of the
Before starting Windows or Linux, add the MAC, IPv4, IPv6 addresses and hostname to:
Before Windows starts, shrink its partition. As received (sizes in 109 bytes):
Will the SuSE rescue system and installer boot? Yes, boots.
The size of the disc is nominally 250Gb (250 × 109 bytes). The installer uses units of 230 bytes, commonly called GiB, and in that unit the total disc size is 233GiB. Mind the units when laying out the disc.
This partitioning was set up using the Linux installer's GUI:
When I've done as much testing in Windows as I want, I'll move the Linux root into partition 2, home into partition 3, merge 6 and 7, and use them as a large media storage area.
I measured the Zino's power consumption. These figures exclude power for the monitor: an old Dell 1902FP, which draws 33 watts when active and 6 watts in standby mode. In production for the audio client role the machine will not have a monitor. The numbers also exclude the powered speakers: 14 watts.
|Power off (S5)||0W|
|Suspend to Disc (Hibernate, S4)||0W|
|Suspend to RAM (S3)||3W|
|Doing nothing (graphics on)||29W|
|Running integer benchmark||40W|
|Memory test (max CPU load)||43W|
So the Zino is not as low power as a Koolu, and it requires a fan for proper cooling, but compared to a normal desktop machine it's quite low. I estimate that a second core would require zero power when idle and 12 to 15 watts when in use (not tested; this is a single core CPU).
