I believe someone at MIT has the necessary changes to either 4.3 or Mt Xinu to make it run on a Vaxstation 2000. >It is my understanding that 4.3 direct from UCB does not run on a >MicroVAX II. The kernel runs, but there is no boot code, and it may support fewer devices than Mt Xinu. >It is my understanding that only Ultrix supports the display tube driver. >... does anyone know of tube driver available for 4.3+NFS? We (actually CSC) have (has) one for 4.3BSD, but I am not sure of its history; it may be derived from the Ultrix driver. The only tricky parts are the virtual console stuff (we dropped it) and getting the Qbus mapped (some hacky code in autoconf.c does it, but this is the wrong way). >...

There are some fancy boot floppies (using the VMS boot loader and a `compress'ed vmunix!) that let you boot via Ethernet from a server. Personally, I have never minded tape boots, but then I have never had to use TK50s either :-) . >Once you've done this, I'd assume that you could replace Ultrix >with 4.3+NFS. Or with 4.3BSD. (Disclaimer: I have not done any of this myself; most of this is secondhand information, except for the stuff about getting the QV driver to work, where I, ah, `provided suggestions' :-) .) -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris
