assign TT1: DDA
Mount DDA0: 'file name'.dsk
E11 comes back with can't open file.
The apostrophes (or quotations marks) should be around the entire filename,
not just the part before the .dsk extension. And you don't need them at all
if the filename doesn't contain blanks or forward slashes or other weird
characters.
It will let me just mount it with out a file. but if
I'm going to write to it, I would guess there needs to
be a container file.
It's true, a DD: controller with no working units isn't very useful!
E11 doesn't give an error message though, since it doesn't want to be
picky about the order of the ASSIGN TT and MOUNT DD commands. For all
it knows you were just about to attach files/etc. to DDA.

sorry for the confusion. "file name" was just there to show how it was laid
out.
test,dsk is what i used

I did not try to turn off the anti virus software, so many be its blocking the
file creation. I will try that tonight

^^^^^^^^
Maybe this is the problem -- are you expecting E11 to create the file?
The MOUNT command is for attaching an emulated drive to an image file that
already exists, so you need a 262,144-byte file. You can create it with
PUTR on DOS (format test.dsk /tu58), or using "dd" if Linux, or actually
(this is a cheesy trick but works for small drives) with E11 itself with
something like:
E11>set cpu 44 (get a CPU type with 22-bit addressing)
E11>dump test.dsk 0:777777 (dump out 256 KB of core -- initially all zeros)

On Windows XP etc. I use fsutil to create empty image files.
Example:
fsutil file createnew test.dsk 262144

I Have most of the E11 figured out. The one area that I still have
problems is the TU58 container and XXDP 2.5. I have made the
container file. Test.tap 256144 bytes
assigned TT1: DDA0
mount DDA0: TEST.TAP
mounted and booted xxdp.dsk
r updat
create DD0: or (DDA0)
Win Xp stops E11 with errors
I would believe the container needs to have Create run on it ???

Dang! You've definitely found a bug in E11 (which I will fix for the next
release), but FWIW it only happens when you're using an undersized .DSK file.
The correct size for a TU58 is 262144 bytes, not 256144 bytes.
Sorry about that!

Wrong again -- dammit!! Sorry about that. I did a lucky test and drew the
wrong conclusion. The actual bug is a trashed register that only happens with
non-blocking disk I/O (so, not on the DOS or stand-alone versions of E11).
The BOOT TT1: command has a stupid new bug too (wrong value in R0) that I
added while making the changes for the weird Terak boot procedure.
Both fixes will be in the next release.
