[comp.sys.atari.8bit] MYDOS and the XEP80

slackey@bbn.com (Stan Lackey) (02/03/90)

First of all, I missed articles 3569-3596 due to my server being
offline for several days. and would be EXTREMELY grateful is someone
would send them to me.

Second - A few months ago I discovered that there was a compatibility
problem between MYDOS and the XEP80 driver furnished by Atari,
mentioned it on the net, and was informed that the XEP would work as
long as DUP was not loaded.  Well, I thought that would be OK for my
plans, but realized an issue: I had no way of loading my editor
package.  The autorun file needed to be the xep driver; the editor
would need to be loaded through the DUP menu.

I tried a few possibilities, and was starting to look at the XEP
driver to include in my image (which I would prefer not to do, so that
the driver can be changed without me needing to reassemble).  I
decided to look at MDUP, and I found the culprit - in mdup2.asm the E:
vector is reloaded (naturally without restarting the 40-col display)
with a comment about compatibility with BASIC autorun programs.  Well
I don't use these, so I removed the whole routine, and guess what!

I don't have a way to transfer files to the net right now, so if
you want a copy of the modified MYDOS on disk through the mail, just
reply.
