Hi, Bruce, Bruce Ray wrote: I have the Release Notes for 4.20. Let me try to be more specific about my problem(s)... :-( I was able to install some disks (3x4G, currently, all identical) and configure the array controller (Mylex DAC1100?) to treat them as a single RAID 5 logical drive. (I had no docs so this was a hit-or-miss proposition :< ). The unit does not have an SCM so I boot from a floppy (4.20MU04). When prompted, I tell it to boot the CD (sd(npsc(pci(0),8),5)). But, when the installer goes looking for disks onto which to copy the software, it complains. Nearest I can tell, all it sees is the *floppy* (which obviously isn't suitable!) So, what trick am I missing? I would assume (!) the logical drive created under the Mylex controller would "magically" appear *somewhere* that the installer could see it (since there are no other provisions for internal drives!) (sigh) I've only got a few more fistfuls of hair that I can pull out... :> Thanks! --don
