The settings dialog now keeps track of MFM/XTIDE/ESDI/IDE channels and SCSI ID's and LUN's;
The IBM PS/2 Model 50 now installs a Model 80-style memory expansion card (MCA ID FCFF) when more than 2 MB RAM is selected, and now supports a maximum of 10 MB RAM.
Re-worked the system pathnames (pc.c), renamed cfg_path to usr_path.
Other small things here and there.
Logitech bus mouse re-worked, should be OK now.
