Hi

I was wondering about what parts of OS/2 is still 16 bit code. The interface part to
applications. So is VIO 16 bit?

2Viking: Yes, VIO, MOU and KBD calls in OS/2 (intel) are 16-bit. So, there is some problem to implement
these API's as is in osFree over L4 microkernel. OS/2 (PPC) introduced 32-bit VIO API, so, osFree probably
must do the same. The question remains how to make osFree compatible with old applications using 16-bit
API's. May be, it is possible to do so via emulation (?). It seems that 16-bit code doesn't work in 32-bit L4
environment, only pure 32-bit code.
