Sooner or later I will probably be porting out drivers to V4. But I was also interested in any driver in general. -- --------------------------------------------------------------------- David Hoopes Tallgras Technologies Inc. uunet!talgras!david 11100 W 82nd St. Voice: (913) 492-6002 x323 Lenexa, Ks 66214

I believe that SVR4.0 was designed to be binary compatable with SVR3.2 drivers but not source compatable (I find it scary to load a SVR3.2 tape driver binary into a SVR4.0 system and have it work). The source interface, though, was designed with change in mind. Although close to the SVR3.2 interface, SVR4.0 has the DDI/DKI standard device interface. In the "Device Driver Interface/Driver Kernel Inteface (DDI/DKI) Reference Manual", there is an "Appendix B: Migration from Release 3.2 to Release 4.0" section that lists the old and the functionally equivilent new interface. -- Robert Adams adams@littlei.intel.com ...!uunet!littlei!adams Disclaimer: Any opinions expressed here are my own and are not representative of Intel Corporation.
