installing windows 7pro32 ensure most X60 tablet functions?

[antigen]

Hi, I was thinking of getting a X60t with SXGA display (pen only input) - I wanted to know that if upgrading to windows 7 32 professional - will all the necessary driver/hot key buttons for the tablet be functional? Is the trackpoint ok as well? Or will I need to manually update some from IBM's site? I came across a few posts here that were dated a few years prior, but I am not sure if the new OS updates include some of these missing factors. I think most of the tablet pen inputs should be native to the OS -

Also, will I be able to boot from an external CD/DVD drive via USB to complete the installation process?

Some ebay listings mentioned that their system bios access is locked, and I will only find out when receiving this - what limitations would I have by not accessing this? I have not seen what things there are in this particular unit's bios menu. Will USB boot automatically (i.e. if I have an external dvd/cd drive or USB flash stick) in such a situation? I had read of some workarounds, but they seem to be out of the scope of my doing and capability. Lastly, if there was a BIOS update available via IBM/Lenovo - would I be able to install this from the windows OS somehow in that particular situation?

One other question out of curiosity - how is flash video playback on this particular unit (i.e. from a wireless a/b/g perspective on streaming 1080p youtube video - apart from factors i.e. network bandwidth capability)

Thanks for any input regarding these inquires.

Unless you know how to overcome a locked BIOS, there is nothing you can do there, no changes, no updates, nothing!
So stay away from those machines.

After W7 installation, install Lenovo's SystemUpdate 4.0 to get all the required/missing drivers that W7 does not have.
With an unlocked BIOS you can boot from USB first, by changing the boot-order in BIOS.
Not sure if F12/select boot device works with a locked BIOS.

I have an X60s (non-tablet), but have never tried streaming video, mine is a pure business machine.

Most of the stuff will be functional out of the box, but update will find and install whatever isn't. I just tested a720P clip on youtube on my underclocked x61t, and it played with ~50% CPU usage, so you should be fine with flash

Thanks for letting me know of theses things - confirmed via seller, bios is not locked/password protected. Looking forward to this arriving.
