I am going to migrate the EDA software environment from Windows NT to Linux but I have still some software components requireing Windows. That's why I use Wine. I own and use some software packages licensed to a valid MAC address (flexlm MAC based license) and the corresponding NIC is present in the Linux system. Using wine-20010824 I get the following message: fixme:win32:DeviceIoControl Unimplemented control 256 for VxD device VNETBIOS I scanned the Web resources and studied the file 'win32/device.c' a little bit but I got no answers to my questions. Is there already a solution/implementation for this service? I am also ready to contribute (at least I hope I'm able to do so and it would be fun ;-) but I need some advice (docus, especially related to the VNETBIOS VxD and some general hints). I'm looking forward for any hints. Michael -- ---------------------------------------- mriedel(a)inova-semiconductors.de ----------------------------------------
