FreeVMS Description

FreeVMS is an OpenVMS-like operating system which can run on several architectures like i386, PPC, Alpha, and many others. FreeVMS is an OpenVMS-like operating system which can run on several architectures like i386, PPC, Alpha, and many others.FreeVMS consists of a POSIX kernel and a DCL command line interpreter. The only architecture currently supported is i386. Here are some key features of "FreeVMS": Supported hardware configuration: · - PCs (i386s) · - Console: VGA · - Network interfaces: ne2k and 3c900 (3c905/3c590 might work, untested) · - Disk interface: IDE Core kernel features: · - Control mechanisms: software interrupts, ASTs · - Synchronization: event flags, locks · - Scheduling, time support, process control and communication · - Memory management: working set list, swapper, pools · - Input/output: QIO, mailboxes, terminal driver · - Image support: VMS images and ELF · - Miscellaneous: logical names Filesystems: · - RMS read/write SEQ (yes) IDX (too little to be usable) · - RMS can be run on both ODS-2 and ext2 (but less functionality on ext2) · - ODS-2 read/write/execute · - ODS-2 initialize · - ODS-2 can have bootable kernel · - ODS-5 readonly · - DFU doing analyze/disk · - XPQ (for ODS-2, and something like it for ext2) Bootloader: · - GRUB with ODS-2 support to boot kernel Clustering: · - SCA/SCS-ish protocols · - Configure process · - CWPS (forcex/stop only) · - MSCP (does not currently work due to lost network packets) Networking: · - CMUIP (with only incoming telnetd) Shell: · - DCL · - mcr, run · - simple @ scripts · - basis CLD and CLI$ support · - simple symbol support · - DCL builtin · - define, goto, logout, stop, exit · - set default/prompt/process · - show default/time · - DCL utilities · - copy, delete, directory, edt, init, mount, search, type · - create /name_table · - set working_set · - show device/system/logical/working_set Editor: · - EDT (from Ozone, and can not yet be used fully) Programming language: · - Bliss (not directly used, and is under development) Linker: · - LINKER (simple, static images. Can do some dynamic linking.) RTL: · - STR$ · - LIB$ What's New in This Release: · Some fixes and new bugs were added. · A GCC variable argument count on i386 was added.
