Since my first posting elicited so many responses (thank you all - the net is really a wonderful thing!) I have another for the list. (Hopefully my manuals should be here in a few weeks, and will resolve most of these types of questions) Sometimes (approx. 75%) when I power up my RT, it will get stuck in a cycle of spinning the floppy disk drive, and never goes to the hard disk to finish booting AIX. Other times, it will poll the diskette drive once, then find the hard disk and come up fine. I end up power cycling (admittedly, a rough procedure on the machine) until it finds the hard drive so I can get the thing running. Is there a jumper I can change somewhere to tell the EESDI controller to try to boot from the hard drive first, then diskette? As always, thanks in advance! /Marty --- Marty Lyons, Ultra Network Technologies, 101 Daggett Dr, San Jose, CA 95134 USA (408) 922-0100 x196, marty@ultra.com, "Home of the 1 Gigabit/Second network" -- --- Marty Lyons, Ultra Network Technologies, 101 Daggett Dr, San Jose, CA 95134 USA (408) 922-0100 x196, marty@ultra.com, "Home of the 1 Gigabit/Second network"

Many of the used machines that we got had dead batteries. The battery costs about $11 at Fry's. The battery maintains information in CMOS that contains (among other things) the boot order. If you system can't maintain the date properly over power down's that is a good sign that the battery is dead or dying. In any case, AIX allows you to set the boot order (or at least the first entry in the boot order) from the keyboard. If I remember correctly, to set it to boot first from the disk 1 hit control-alt-num-1. (e.g. hit control + alt + numeric pad "1"). In any case the VRM techinical reference manual should have this information (when you get it). Otherwise it can also be done with the 4.3 "sautil" diskette using the "ipl" menu entry. Call me the above isn't sufficient. ---------------------------------------------------------------- The above views are my own, not those of my employer.
