Impatient soul that I am, I didn't want to wait for Sun to mail me a PROM upgrade when I upgraded my 3/160 to 4.0 a couple of weeks ago. As you all know, the main problem here is that the older PROMs can't read the QIC-24 format 1/4" cartridges that 4.0 is distributed on. But don't despair. All you have to do is copy a few files from the QIC-24 tapes and write them on to a QIC-11 tape, and then you're home free. (All this assumes that you have a Sun already running, but why are your PROMs so old if you don't?) The files that need to be copied are the boot program, the MUNIX image (only if you need to format anything), and the miniroot. For some reason you can read the standalone copy program off the QIC-24 tape. Once you're up and running, pop the QIC-11 tape out and put the QIC-24 distrib tape back in. Sun is now taking two weeks or more to ship the PROM upgrade kits, so this might save you some time if you don't mind taking a few risks with your upgrade. Note that I'm not recommending this, especially if you aren't pretty savvy about Unix installation, but it *is* possible. Mike Caplinger, mc@moc.jpl.nasa.gov
