RE: Driver for X11

["Suhaib Siddiqi" <ssiddiqi at inspirepharm dot com>]

Someone else?  As far as I know Jan Rouvilan was looking into
XF86SUP.SYS driver.  If the e-mail is from him then sure please
discuss with him, if it is froim someone else then I need to know
first who is working.
I prefer people communicate via mailing list instead of private
messages.  this way others can be kept informed and upto date.

All we need Windows Nt and 98 support.  DOS driver is not the way to
go "I think".
