Subject: ZCPR3 STARTUP

Rick:

After much experimenting, I have gotten ZCPR3 up and running on
my H89, using a BIOS mod written by Jerry Furst.  One problem,
however:

1. ZCPR3 (correctly) expects to find STARTUP.COM and tries to run
it on cold boot.

2. I created STARTUP.COM using ALIAS, consisting only of the LDR
commands needed to load the system segments.

3. When ZCPR3 tries to run this ALIAS, it returns either an
"Ovfl" error, or it fills the Shell Stack.  (Didn't think ALIAS
used the Shell Stack!)

4. If I run the same ALIAS (STARTUP) from the ZCPR3 prompt, it
works fine.

I spoke with Jerry Furst, the BIOS mod author, and he reported
that he had the same problem.  He was able to work around only by
using the ZCPR2 STARTUP.COM program.

The STARTUP feature is important to making these systems turn-key
for users.  I can only figure that something is going wrong in
trying to load the system segments.

Help, please.  What's happening here?  Has this affected anyone
else?  How do I fix it?

Once I get this licked, I'll upload Jerry's auto-install ZCPR3
files for the H89 with this fix included.  He has done a nice
job, and you can install ZCPR3 from scratch on an H89 in about 75
minutes without a hitch.

Thanks in advance.
