Olivetti M21 info wanted

I have recovered an Olivetti M21. Its an 8086 based system with floppy disk and 20 Mb hard disk in a case reminiscent of the original Compaq. Anyone have technical info on this beastie? I noticed an extra DA-9 (?) connector on the mother board which is not available when the covers are in place - what's that for?. Also the definition of the two DIP switch blocks on the mother-board which do not seem to follow the IBM spec. And thirdly how to get into setup, or a copy of the setup disk. I have tentativly decided to dedicate this system to an attempt to port the Z80 UN*X kernel that Allison mentioned a couple of weeks ago. Got it all fired up with DOS 3.1 and Turbo C 1.5 at the moment, I will be adding a vintage copy of BRIEF and away I go..... As an aside, in looking through my store of 5-1/4" disks, I see I have IBM versions of DOS 1.0, 1.10, 2.00, 3.10, and 3.30, gosh they go back a ways. Also found some MS disks with old versions of Windows and a GWBasic adaptation kit. Regards, -- Hans B.
