Windows 7 - Satellite M100-222 - Solved!
I solved problems with "Windows 7" on "Toshiba" "Satellite" M100-222. For everyone who want use Windows 7 on this model!
Install Window 7! Download specially drivers for "Toshiba" "Satellite" M100-222 (PSMA1E).
Download BIOS v5.60! Update BIOS! Then install drivers.
Display drivers (ATI Mobility Radeon x1400) you can download from here - http://catalog.update.microsoft.com/v7/site/Home.aspx
Also you can download sound drivers ("Realtek" high definition audio codecs) from www.realtek.com.tw (if you care about new version of these drivers).
Install "Toshiba" VAP v1.2.40 (Value added package).
Follow system restarts during these operations.
Everything will work correctly! I'm testing drivers with system compatibility now.
Also Card Bus device drivers.
