We tried to get the Release Candidate of Windows 8 installed on a Toshiba Portege Z830 with not very positive results.
This go around with the RTM bits was about 96% successful. We ended up needing the Bluetooth driver and the Fingerprint Reader driver from Toshiba's site.
After verifying the versions of the software we downloaded the versions attached to the Z930-007 for Windows 7 since they were newer.
In addition to those two drivers the Toshiba Service Station should be installed to keep the machine's drivers and BIOS up to date. Also, to get the special function keys to work and the ability to toggle the Touch Pad on and off requires the Toshiba Value Added Package.
In the RC we were not able to get our 14" Toshiba USB external monitor to initialize at all. The DisplayLink drivers were non-existent in the OS and the Windows 7 drivers refused to install at all. We are happy to report that the DisplayLink driver is built into RTM Windows 8.
So, we are able to run the external display via USB 2. Besides the ability to Extend the primary display for two distinct desktops we are able to Duplicate the primary display on the external display for small one or two person presentations.
A pico projector would be another option but a power supply is required. The Toshiba USB monitor is powered by the USB connection as well so no additional cables or power requirements are to be had.
There is one very noticeable addition in computing behaviour now that we have Windows 8 on the Surface, multi-monitor systems in the shop, and now the Portege Z830 with single or dual display: The tendency to reach over and touch the monitor. This tendency emerged after acquiring the Surface. :)
