Does Windows 7 Release Candidate work on the Samsung Q1EX? In short, not quite, not yet.
With reports that W7RC is installing well on other tablets and convertible PCs, I gave it a try on my new Samsung Q1EX. Having installed it on several other computers including a Fujistu P1610 (worked great), the look of Windows XP is starting to look pretty dated.
Backed up my SSD on the Samsung Q1EX as an image on a USB HDD using Acronis. Then did a clean install of W7RC from the DVD I had created (using a USB DVD player and keyboard. Installed without errors, but does not install a WLAN driver or touchscreen drivers. After some experimenting (and reloading W7RC after snafus), I found that the Win XP driver for WLAN (the one for Marvel) gives you the WLAN. Only partial success with the touchscreen. The only touchscreen driver that seems to give you any functionality is the XP “TSP” driver that loads the eGalaxTouch utility. The other drivers marked as touchscreen or tablet (either XP or Vista versions) do not seem to work alone or in combination with the TSP driver. The issue may be that the touchscreen is a PS-2 hardware item. W7RC does not recognize the tablet function, and does not provide the tablet/pen settings in control panel. To even log on you need a USB keyboard to enter the password. No access to a tablet-style keyboard.
I contacted Samsung asking about the status of Windows 7 drivers. They are no help based on this response:
Samsung does not provide any support or drivers for altering the Operating System on the Q1 line of Ultra Mobile PCs. We do not provide any drivers for Windows 7 at this time for any of our mobile computing products.
So much for customer service from Samsung. Looks like I’ll be sticking with XP for awhile on the Q1EX until Microsoft or Samsung provides driver support.
