I have some more quirks to report with the Zen.
1) The device manager in windows XP reports that there are 3 monitors on the system. This seems odd considering I have only 1 monitor and 1 (onboard) video driver. One of the monitors is reported as a "plug and play" monitor. The other 2 are reported as "default" monitors. If I remove them from the system using the device manager windows will "redetect" and install them when I reboot.
Mine shows the same thing. All "3" monitors also show up in the Display Properties screen.
This quirk, along with the apparent inability to load 3rd party host controller drivers from a USB floppy should be weighed heavily by anyone considering using anything other than an IDE drive in the Zen. Windows XP gives no other option than to load those drivers from a floppy drive.
That's not MS's fault. Shuttle decided not to put a floppy header on the mobo. IMHO, that's a stupid decision. The floppy is far from dead, no matter how much the anti-floppiests might wish it were.
3) At boot there is an extended delay while the first Windows XP splash screen appears (the one with the little animated progress bar at the bottom). In my Iwill, the progress bar would go across one time, the splash screen would disappear, a short 2 or 3 second delay with a blank screen would transpire, then the welcome screen would appear. In the Zen, everything seems to be the same with the exception of the length of time the splash screen is present. It remains up for no less than six swipes of the progess bar, adding several seconds to the overall boot time. It should be noted that I'm using a faster bus (800 mhz compared to 533), faster ram (DDR400 compared to DDR266) and a slightly slower CPU clock speed (3.00 compared to 3.06) with the Zen than I had in the Iwill. Those numbers would leave me to expect that performance would be improved rather than degraded at boot. The rest of the system does seem to be improved, however. Things are snappier with the Zen.
I sure don't have that problem with my ST62K. It cold boots to a fully loaded desktop in 35 seconds. The progress bar shows up right after the POST screen and takes about 1.75 swipes before the desktop starts loading. My guess is that you have some driver issues, or more likely, something with your add-in SATA card.
