Has this project fissled out or > has other projects taken priority? That was me... I've been working on it on and off, but haven't really spent too much time on it. The current status is: - Interrupt handling for doscmd is better. - vm86 now has vme support. - access to the full I/O space from a user process. I did start a port of Linux's dosemu, but have been so revolted at their tangled makefile setup, that I haven't gotten very far. There are also some additional issues of what to pass back forth on the stack that I haven't bothered to address (yet). I have a version of vm86 for -current that I can polish up and submit in the next week if there is interest. This is be slightly different than the version on the 2.2.2 cdrom, due to the relocation of the user pages. I could also retrofit some of the patches back into 2.2.2, if there is any chnance that they would be accepted into the tree. The only thing that would not be possible under 2.2.2 is the iospace support, as that depends on the u-page change in -current. -- Jonathan
