on Virtual PC 2007, any S3 trio drivers crash the virtualizator when I type win.com when I install them on Windows 3.1 IBM Japanase (1993-06), the Generic patched SVGA driver does not work well after switching from the DOS prompt to Windows mode.

there is a patch to the Svga driver hear for VMware http://sites.google.com/site/chitchatvmback/misc

that one screws up the Window mode after switching from DOS mode to Window mode.

edit oemsetup.inf to disable the copy of non-Japanese-enabled system font files from S3's driver packages.

Sorry for my poor English m(_ _)m
