This was not from HS.

The only bootable partitions are the first partitions on the hard

True.  DOS boots from C.

He does.  The other primary partitions are not bootable except for the
1st one on Drive 1.  And that's a backup in case something happens with
Drive 0. I can switch drives & still access the drives.

I understand.  But remember when he was setting this up I was running
DOS & Win3X.

 ML> more.  My "top" drive letter is K: for the 100 MB Zip drive.

The present setup was to keep the from having a large number of drive
letters.  Before I started with upgrading stuff I was running Dos 3.3 &
had drive letters up to P without any thing like a zip drive attached.
Once the CDROM etc gets added these add up.

And we are discussing this on an ongoing basis.  We plan to have it
worked out by Nov 21. That is the schedule for THE day at the moment.

HS is not an OS/2 guru.  And he knows it.  He knows more about DOS &
Linux world. (Have dream machine for Linux.  Will take many years of
development.  After all took 10 years to get this unit) Many moons ago
he did OS/2 installs & I am forwarding everything from here to him to
update his info.  And we're trying to set the hard drives up initially
for long term planning.

But I am doing the install.  Keep fingers crossed X.

... The ATM just asked if I wanted to go double or nothing!
