FOR USERS OF AUTOCAD RELEASE 12 The current drivers also operate with AutoCAD R12. Note that in order to work with R12, the proper EXP file must be renamed and copied to driver directory. For example: COPY C:\BOOST\BOOST16M.EXP C:\ACAD12\DRV\RCBST16M.EXP The new file name must start with characters RC. Although these drivers allow operation with R12, they do not take advantage of the new features of R12. For example the 32-bit display list is not yet supported in this version, V5.30, boost drivers. Since AutoDesk has not released final specifications for ADI 4.2, the driver interface needed to support R12, we are unable to release new drivers now. They will be available on the BBS when released.
