You may be referring to something else here, but I believe the "nothing boots from
beyond the 1024K cyl. boundary" (without the aid of some dedicated boot loader
situated very early on the HD) still holds true. At a recent SCOUG meeting, Kim
promised me faithfully that the ECS Boot Manager *could* install ECS beyond
that point, where it would be fully functional. In the course of my system upgrades,
Tony and I tried to do this -- several times -- and it just does not work. Maybe
Kim has something else at Serenity that hasn't been released yet, but the last ECS
rev. of Boot Mgr. still leaves anything past this point greyed out. Verboten.
Can't get there from here.

Steven, I understand you made some reference to a testcase kernel that possibly
resolves this issue ? Well, doesn't Boot Mgr. have to get into the act before you even
get that far ? In any case, I wouldn't have felt like experimenting with what is
intended to become my next Production partition . . . .

Agreed, and I do. (Substitute W2K for Linux, in my case. At the moment,
I have W4, WSEB, ECS, and a pair of W2Ks, one being Maintenance for
the other.) So far, Boot Mgr. has been fulfilling the basic OS-mediation
task, so I haven't missed System Commander too much.

Yes, planning ahead -- or at least trying to -- is a good and important thing.
Once you have a complex scheme in place, with its attendant driver lettering
(which one probably wants to keep as constant between the OSes as possible),
there is a big investment in it, and making changes to this plan becomes very
unappealing.
