Don't worry. This is a "Microsoft Free Zone". :-)
I don't even have a copy of "DOS" to run setup
on those sh*^^y pc interface cards.

Don't blame ME! I wasn't ask anything about "geometry." I suspect that
the problem has to do with the false assumptions used for these generic
allocations.

OK. I'll "buy" a reinstall. I can move the good data off of another disk
and change the SCSI address when I get finished.
Here's what I think I want. What do you suggest for details.
1) At least 3 HD will start with a small (30M-40M) bootable root partition.
2) Every disk will support some swap (say 60M == I'll go to mfs /tmp)
3) Each disk will have a moderate partition for /usr, part of /home, or similar
4) Each disk will have a large partition (To be combined into a huge ccd
partition later) for /pub
I would prefer to set it up in sysinstall, but will drop back to the
"strange incantations" if necessary.
Please "hold my hand" a bit. I need a system that can reboot itself
without pressing the keyboard at just the right instant while booting from
a floppy.
Thanks in advance,
Richard
BTW. The drives are Seagate ST12550N. I damn hot 2G drive. (Especially with
the cover off the box.. ouch)
An old label I manually generated "before" the new-fangled way of doing
geometry.
